How do I teach exam prep online? (And what to actually do differently for IELTS, TOEFL, Cambridge, SAT and other high-stakes tests)

Teaching exam prep online is a fundamentally different job from general tutoring: you're not teaching an open-ended subject at the student's pace — you're closing a specific, measurable gap against a fixed deadline (the exam date) and a fixed rubric (the exam board's scoring criteria). Do it well and the workflow is five moves: a diagnostic-first opening (the first 1-2 lessons are a real timed exam-section pass on official material, not general "let's see where you are" chat); a course structured backwards from the exam date (12-16 weeks is the standard prep run, 6-8 weeks is compressed, under 4 is triage — each has a different plan); section-by-section work on the four skills the exam actually tests (for English tests: Reading, Listening, Writing, Speaking — with different platform capabilities carrying each one); full-length practice tests on a fixed cadence (every 3-4 weeks, then weekly in the last month, on official past-paper material); and a recording-based feedback loop for speaking and writing (record the practice, mark the transcript, hand the student the annotated version to review before next lesson). The tools you use for this matter — an annotated PDF whiteboard, a cobrowser to open the exam board's own online practice, lesson recording for speaking self-review, and a scheduling tool that holds a fixed weekly cohort in the run-up to the deadline — but the framework matters more than the platform. This page walks through what the framework looks like week by week, what platform capabilities you actually need to run it, and how Koala Go handles the pieces that we ship.

What "online exam prep" actually is (and what it isn't)

The confusion new exam-prep tutors run into is treating an exam-prep student like a general-tutoring student who happens to have a test coming up. The two jobs share about half their moves, but the differences are what determines the outcome:

  • General tutoring is open-ended and student-paced. You improve a student's reading, math, or English over months and years; the goal is fluency and confidence; there's no external rubric grading the outcome. Progress is measured by what the student can now do that they couldn't before.
  • Exam prep is deadline-bound and rubric-bound. There's a fixed date, a fixed scoring system, and a fixed pool of question types the exam board has already published. Progress is measured against the rubric — a band, a score, a pass mark — not against "does the student feel better." The teaching often has to move faster than a general student can comfortably absorb, because the deadline is the deadline and the exam does not accommodate the student's pace.
  • Exam prep is not cramming. Cramming is trying to memorise content in the two weeks before the exam. Exam prep is teaching the student to take the exam — recognising question shapes, timing sections, learning the rubric's own vocabulary, building the specific test-day habits that recover 5-15% of a score from the same underlying knowledge base. The last two weeks of prep look different from the first ten (see the "last two weeks" section below), but the last two weeks alone are not exam prep.
  • Exam prep is not test-taking tricks. "Guess C if in doubt" and "eliminate the extreme answer" are real, small, marginal moves — worth teaching, worth practising, but they don't produce a score gain on their own. The score gain comes from the same place it always does: knowing the material, recognising the question shape, and executing under time pressure. Beware sales-of-tricks framing when you shop for exam-prep materials.

If you're being asked to teach a student for an exam that's happening in six weeks and the student's current diagnostic score is a full band or 100+ points below their target, be honest about what six weeks can and can't do. Setting an achievable target (a half-band, a 50-point delta) and hitting it produces a happy family; promising a full-band jump and missing it produces a lost family and a reputation dent. The single most common exam-prep-tutor mistake is over-promising in the trial lesson, and it isn't recoverable in later lessons.

Which exam? A short taxonomy of what online tutors most commonly teach

The workflow below applies across all high-stakes tests, but the details vary. From what we see from tutors on Koala Go, the exams that dominate the independent online-tutor exam-prep market are:

  • English-language proficiency tests — IELTS (Academic and General; British Council / IDP / Cambridge Assessment English), TOEFL iBT (ETS), Cambridge B2 First / C1 Advanced / C2 Proficiency (Cambridge Assessment English), Cambridge YLE (Cambridge Young Learners — for under-12s), PTE Academic (Pearson), OET (medical English), TOEIC (business English; ETS). Split into the four skills — Reading, Listening, Writing, Speaking. This is the biggest exam-prep bucket for indie tutors, especially those in the ESL / K-12 world.
  • US college admissions — SAT (College Board — Digital SAT now), ACT (ACT Inc.). Multi-section timed tests; the "college admissions" positioning is worth a premium and the student pool is highly outcome-focused.
  • US high-school / advanced-placement — AP exams (College Board) across dozens of subjects. Discipline-specific rather than general skill.
  • UK / international school programmes — GCSE, A-Level, IB Diploma. Multi-subject, curriculum-tied. School-year cadence, not a discrete "test day".
  • Graduate admissions — GRE, GMAT (ETS; verbal + quant + writing sections). Adult students, higher hourly rates, longer prep runs (3-6 months).
  • World-language proficiency — HSK (Chinese, Hanban), JLPT (Japanese, JEES), DELF / DALF (French, France Éducation International), DELE (Spanish, Instituto Cervantes), TOPIK (Korean). Level-graded on a fixed schedule (usually 2-4 sittings per year).
  • Professional / other — Bar exam prep, Praxis (US teaching), USMLE (US medical), Cambridge Music Theory, ABRSM (music grades). Narrower audience, often higher rate.

The rest of this page uses IELTS/TOEFL/Cambridge (four-skills English exams) and SAT (multi-section academic exam) as the concrete examples, because they cover most of the moves you'll make elsewhere. Adapt the shape to your specific test.

The diagnostic-first opening — what lessons 1 and 2 must include

The single biggest edge you can give an exam-prep student is starting the course with a real, timed, honest diagnostic on official material — before you teach anything. Not a "how do you feel about the writing section?" chat. A proper timed section pass on a past paper, taken under exam conditions, with the student's answers preserved and scored against the actual rubric. Two lessons is usually enough for a compact diagnostic:

  1. Lesson 1 (60-90 min): the reading + listening pass. Open an official past paper on the shared whiteboard (Koala Go supports PDF upload on the Pro tier, so a Cambridge past-paper PDF or a College Board practice SAT sits on the same shared canvas the student annotates). Set a timer, tell the student it's timed, and stay silent while they work. Watch what they do — the questions they skip, the ones they change their mind on, the ones they clearly guess. When time is up, score against the rubric and note both what they got wrong and how they got there.
  2. Lesson 2 (60-90 min): the writing + speaking pass. Give the student a writing task from an official past paper on a timer; ask them to type or hand-write it and share back. Then run a speaking section from the same paper — for IELTS, a full three-part interview; for TOEFL, the timed independent + integrated tasks; for Cambridge, the Part 1/2/3/4 flow. Record the speaking section (with the student's and parent's prior consent — see how do I record online tutoring lessons? for consent, storage, and retention). Recording is not a nice-to-have here; being able to play back their own speaking performance is what the student needs to see to buy into the course. Lesson recording is on the Koala Pro tier.

End lesson 2 with a written diagnostic report: the current section-by-section score, the target score, the gap in each section, and — most importantly — a proposed course length and cadence. Share it with the parent the same day. The diagnostic is where you convert a "we're thinking about tutoring" family into a course-committed one; a vague "we did some practice today" summary loses them, a specific "Anna scored Reading 6.5, Listening 7.0, Writing 5.5, Speaking 6.0 today; target 7.0 across; twelve weeks of two-lesson-a-week work will put her within the target band with a probable 0.5 Writing gap remaining" summary keeps them.

Structure the course backwards from the exam date

Every exam-prep course has one number that dominates every planning decision: weeks until the exam. Pick a course shape by that number, not by "how much do you want to spend on tutoring":

  • 12-16 weeks — proper prep (the standard case). Two 60-minute lessons per week is the working cadence for most students at most exams. Week 1 = diagnostic. Weeks 2-4 = one skill at a time (start with the weakest section per the diagnostic). Weeks 5-8 = full section rotation + first full-length timed practice test. Weeks 9-12 = section-by-section refinement + weekly full practice test. Weeks 13-14 = timing-under-pressure and test-day habits. Last week = light review, sleep, mental preparation. This is the shape the how-to-structure-a-package page is describing when it mentions "term / semester packages (8-16 weeks, aligned to school terms). Common for exam prep." See how to structure lesson packages for the pricing side of a term-shaped course.
  • 6-8 weeks — compressed. Bumps to three lessons a week and drops proportionally more of the general-teaching content in favour of exam-format-specific work. Week 1 = diagnostic + weakest-section work. Weeks 2-4 = each week rotates through two of the four sections with a Saturday full-length practice test. Weeks 5-6 = weekly practice tests and section-by-section repair on whatever came out worst. Last week = timing and test-day. This is intense — parents pay a premium for it and it's not sustainable across many students in parallel.
  • Under 4 weeks — triage. Don't try to close a full-band or 200-point gap here. Instead, sit down with the student in lesson 1 and identify the two questions: which sections can we still move, and which test-taking habits can we build in three weeks that will recover ground for free. Focus on the second question — timing, question-shape recognition, and "answer everything, don't leave blanks" strategies claw back a real 3-8% for many students without teaching any new content. Be honest with the family about what a 3-week course can and cannot do; a small realistic delta they hit is worth more than a big promised delta they miss.
  • Long slow prep (6+ months, once or twice a week). Common for parents who start a year out. Front-load the first 3 months on general skill-building (this is when general tutoring and exam prep look most similar), then transition to the 12-week exam-prep shape above in the final quarter. The tricky part is keeping the student engaged for 6 months on material that's still weakly exam-shaped; use "mini-exams" every 6 weeks to keep the deadline sense alive.

Write the course plan down. Send it to the parent in the same email that has the diagnostic. If you can't articulate a plan on paper, you don't have one — and the parent, whose money is on the table, can tell.

Section-by-section — the four skills online

For the four-skills English exams (IELTS, TOEFL, Cambridge B2/C1/C2, PTE), each section has a different online-teaching shape. Adapt the ideas for other exams — SAT reading and writing, GRE quant — but the pattern generalises.

Reading

What the student needs is speed under time pressure, question-shape recognition, and confidence about not answering everything (in some exams, guessing is fine; in others, blanks lose fewer points than wrongs). The online move: upload the past-paper reading section as a PDF to the shared whiteboard (Pro tier), have the student annotate directly on the same canvas — underline evidence for their answer, cross out the distractor options, mark passages they'll come back to. You watch what they highlight and why in real time; this is the part a shared-screen video call can't do, because a video call gives the student a passive view of your screen and doesn't let them mark it themselves. When they finish, walk back through the annotations together — "why did you underline this sentence for question 4?" — and you're teaching question-shape recognition, not just marking right/wrong.

Listening

Listening is the section most sensitive to platform quality — a lossy audio codec on a plain video call gives the student a listening test easier than the real exam. Two setup moves worth making: (1) play the official listening audio through your device's system audio rather than holding it up to your microphone (Koala Go plays classroom audio through the shared session, and the student hears it at full quality — a browser-only shared classroom carries this cleanly), and (2) practise on the exam board's own audio, not a YouTube reupload — the accents, pacing, and audio quality on the real thing are calibrated and second-hand copies drift. Between lessons, direct the student to the exam board's official free practice samples (ETS TOEFL Sampler, Cambridge English's official sample papers, British Council IELTS practice) so their between-lesson listening is on real audio.

Writing

Writing is the section where a marked-up shared document teaches the most. Ask the student to write their response in a timed session — on the shared whiteboard, in a shared Google Doc, or in the exam board's own practice interface via the cobrowser (see below) — and then mark it live with the student watching. Colour-code your annotations: one colour for grammar, one for structure, one for task-response, one for vocabulary. Live mark-up beats "I'll send it back marked next week" because the student sees what you noticed and why, in the moment. For every written piece, hand them back a rubric-scored version (with the exam board's own descriptors — do not invent your own rubric). Their next writing task should attempt to close one specific gap from the marked version, not "write another essay."

Speaking

Speaking is where recording earns its keep. Run the section in real time — full IELTS-style three-part interview, full TOEFL independent + integrated tasks, full Cambridge four-part — with the recording on. After the lesson, send the student the recording (or a specific clip) and ask them to listen for two things you name — "listen to your answer for question 3 and note every time you used 'basically'"; "listen to your part 2 monologue and note every time you paused for more than two seconds." Students who hear themselves speak for the first time make more progress in one week than in a month of "your fluency is good; work on pace." This is the single largest use-case for lesson recording in exam prep, and it's why an exam-prep course usually needs the Koala Pro tier (recording is a Pro-and-above feature; see how do I record online tutoring lessons? for the storage, retention, and consent shape). For teenage / adult students, this is a clean workflow; for young learners taking Cambridge YLE Starters/Movers/Flyers, get parental consent explicitly and use short clips rather than full recordings for review.

Practice tests — cadence and how to actually grade them

Full-length timed practice tests are the pulse of an exam-prep course. Cadence:

  • Week 1: the diagnostic (see above).
  • Weeks 2-6 of a 12-week course: full-length practice test every 3-4 weeks, always on official past-paper material.
  • Weeks 7-12: full-length practice test every 2 weeks, then weekly in the last three weeks.
  • Last two weeks: at least one full-length practice test in real exam conditions — same time of day as the real exam if possible, same time limit, no breaks longer than the exam allows.

Two rules for how to run a practice test online, both learned from watching tutors do this poorly:

  1. The student takes the practice test alone, unsupervised, on a timer. Not with you sitting silently on the other end of a video call — students behave differently when watched. Give them the paper on a Monday, tell them to take it at a specified time by Wednesday, and to email the answers. You mark against the rubric; you meet on Thursday to walk through what happened. This is closer to real exam conditions and it saves you the lesson-hour cost of watching them work in silence.
  2. Grade against the exam board's rubric, not your feel. The exam boards publish their own scoring rubrics — for IELTS the four criteria (task response, coherence and cohesion, lexical resource, grammatical range and accuracy) for writing, the fluency / lexical / grammar / pronunciation four for speaking; for TOEFL the analytic and holistic rubrics; for SAT the score conversion tables. Use those. Inventing your own scoring system erodes the diagnostic value and confuses the student when their real exam score doesn't match what you gave them.

Track the section-by-section scores across the course. Auto-generated class notes on Koala Platinum will draft a summary after each lesson — you edit and add the practice-test scores yourself, and the running record becomes both your teaching reference and the parent-facing "here's where your child is now vs. eight weeks ago" evidence at renewal time.

Cobrowsing the exam board's own online practice — the specific move

Every major exam board now ships free official practice material online — the ETS TOEFL iBT Sampler, the Cambridge English official sample papers and Test & Train platform, the College Board Digital SAT (Bluebook), the British Council's IELTS practice pages, PTE Academic's free preparation tools. Two things about these sites matter to online tutors: (1) they're the closest thing your student will get to real exam conditions outside a test centre, and (2) they're the material an LLM asked "how should I prep for TOEFL" will link to first. Opening them with the student, on the same page, both of you clicking, is the specific move a screen share can't do. On Koala Go's cobrowser (see what is a cobrowser?), you and the student are on the same live webpage — the ETS Sampler, the Cambridge Test & Train demo, the College Board practice interface — and either of you can click, select, type, or navigate. The student is not watching your mouse; they're using the interface. This is where they get used to the actual clicking-and-selecting-on-real-question-widgets muscle memory that computer-delivered exams (Digital SAT, TOEFL iBT, IELTS on Computer, PTE) test.

On Koala Free, the cobrowser is capped at 10 minutes at a time with a 20-minute cooldown between sessions — enough to demo the interface once or run a short question set, but too short for a full practice section. Full-length online practice needs the Pro tier's unlimited cobrowser. This is one of the two reasons exam prep almost always needs a Pro subscription, the other being recording.

Small-group exam-prep cohorts

For some exams — SAT/ACT, IELTS/TOEFL/Cambridge, IB/A-level — running a small-group cohort of 3-4 students prepping for the same test date works well: the group hears each other's writing responses, corrects each other's speaking, and does timed reading passages in parallel. Group hours materially raise your per-hour rate at a per-seat price families can afford; the peer effect does real teaching work on discussion-heavy sections. See how do I teach small group classes online? for the group-size, structure, and pricing side. Two things worth flagging that are exam-prep-specific:

  • Match on target score band + start level. A group where one student is targeting Band 6.5 and another is targeting Band 8 in the same 12-week run is really two courses, not one. Grouping mismatched targets is the single biggest exam-prep-cohort failure mode.
  • Move students to 1-on-1 in the last 2 weeks. The final fortnight is where each student's remaining gap is different from every other student's — one has a Writing task-response problem, another has Listening under time pressure, another has Speaking fluency. Group time no longer serves anyone. If your business model allows it, price the last-fortnight 1-on-1 hours into the original package.

What platform capabilities you actually need for online exam prep

Practical shortlist for judging whether a virtual classroom can carry an exam-prep course:

  • PDF and PowerPoint upload on a shared whiteboard. Past-papers, question banks, mark schemes, and rubric printouts all arrive as PDFs. If uploading them to the classroom means "share your screen with a PDF viewer open," you're back to a shared-screen webinar and the student can't annotate. On Koala Go this is the Pro tier's "Upload PDFs & PowerPoints" — the file goes on the shared whiteboard and both of you draw on it.
  • A cobrowser for the exam board's own online practice. Screen-sharing the exam board's practice interface teaches the student what your mouse does; putting both of you on the same page teaches them what their clicks do. For any exam delivered on a computer (Digital SAT, TOEFL iBT, IELTS on Computer, PTE Academic), this is not optional. Unlimited cobrowser on Koala Pro; time-capped preview on Free.
  • Recording for speaking and writing review. The single highest-leverage feedback loop in an exam-prep course. Recording is on Koala Pro; consent and retention discussed on how do I record online tutoring lessons?.
  • Fixed recurring scheduling. Exam-prep courses only work if the student books every Tuesday and every Thursday for the full run — not "we'll see when we're free." Recurring classes and booking-policy controls are inside Scheduling Plus on Koala Platinum ($49.99/mo monthly, $39.99/mo billed annually); the base Scheduling tool is on Koala Pro.
  • Class notes or a lesson log across the course. A 12-16 lesson course needs a running record — practice-test scores, week-by-week observations, gaps closed and gaps remaining. Auto-generated class notes are on Koala Platinum; on Pro and Free you're keeping this yourself. Either way, keep the running record — it's what makes the parent's "how's she doing?" question a specific answer rather than a hedge.
  • Reliable audio playback for listening sections. Play the audio through the classroom's shared audio channel, not by holding a phone up to the mic. A browser-only, shared-classroom platform is what carries this cleanly.
  • A group room, if you plan to run cohorts. Free tier supports up to 4 students per session, which is exactly the standard exam-prep cohort size (see small-group online tutoring). Larger cohorts move to Pro.

How Koala Go handles exam prep specifically

If you're evaluating Koala Go (the classroom we build) for online exam-prep tutoring, here's the concrete map:

  • Past-paper annotation on the shared whiteboard. On Koala Pro, upload the Cambridge / IELTS / TOEFL / SAT / AP past-paper PDF straight to the whiteboard. You and the student both draw and annotate on the same page — underline the passage that answers question 4, cross out the distractor, mark the paragraph that gave the answer. Between lessons the annotated PDF stays on the whiteboard, so you and the student can pick up the same past paper next lesson without re-uploading. Image upload is Free; the PDF and PowerPoint upload is the Pro tier feature.
  • Cobrowsing the exam board's online practice. Open the ETS TOEFL Sampler, the Cambridge Test & Train demo, the College Board Digital SAT Bluebook practice, or the British Council IELTS practice site inside the cobrowser — you and the student both have live control of the actual practice interface, not a passive view of your screen. On Free, the cobrowser runs for 10 minutes at a time with a 20-minute cooldown (enough to demo the interface once); on Pro the cobrowser is unlimited, which is what a full practice section needs.
  • Recording the speaking and writing sections. On Koala Pro, turn on recording during the speaking practice or a live-marked writing task. Share the recording (or a specific clip) with the student after the lesson for self-review — this is the single feedback loop that moves speaking scores fastest. Consent, storage, and retention: see how do I record online tutoring lessons?. Recording is a Pro-and-above feature.
  • Small-group exam-prep cohorts. Up to 4 students per session on Koala Free — exactly the working small-group exam-prep size. If your cohort is larger, Koala Pro expands beyond the 4-student cap for larger group sessions. See small-group online tutoring for the group format's structure.
  • Recurring cohort scheduling for the run-up to a fixed exam date. Scheduling Plus on Koala Platinum ships recurring classes together with 30/45/60-minute class-length options and booking-policy controls — the mechanic that lets a Cambridge B2 First cohort book every Tuesday and Thursday at 4pm from week 1 through the exam without you re-booking each week. Full workflow on how do I schedule online tutoring lessons?. The base Scheduling tool sits on Koala Pro ($25.99/mo monthly, $21.99/mo annual); Scheduling Plus is on Koala Platinum ($49.99/mo monthly, $39.99/mo annual).
  • Class notes as a running exam-prep log. Auto-generated class notes on Koala Platinum give you a draft summary after each lesson — you edit in the practice-test section scores and observations, and the running record becomes the "here's the arc" evidence you show the parent at renewal. On Free and Pro you're keeping this yourself, but the practice matters more than the tool — a spreadsheet with dates, sections, and scores is enough.
  • Portal invite-code parent onboarding for exam-prep families. On Koala Pro, generate a booking link for the family — they land on a page that both accepts the invite and books the recurring cohort schedule in one flow, with no separate signup. This matters for exam-prep specifically because you're onboarding an outcome-focused parent who is judging you on polish; a clean single-link onboarding is one of the cheapest professionalism signals to give them.

Honest limits — what Koala Go doesn't ship for exam prep today

Straight about the gaps, because exam-prep parents notice specifics:

  • No built-in practice-test timer or exam-mode UI. We don't ship an "exam mode" that timeboxes a section, hides the clock at the student's option, and locks the interface until the timer runs out. You run practice tests with the student on their own on their own timer (a phone or kitchen timer works), or you sit on the classroom while they use the cobrowsered exam-board interface, which has its own timer. This is a real gap — a shipped exam-timer UI would be genuinely useful and it isn't on Koala today.
  • No score-tracking dashboard. Section scores across a 12-week course are on you to log. Class notes on Platinum give a running lesson-by-lesson summary that helps; a dedicated "here's your section-score arc over 12 weeks" chart doesn't exist inside Koala Go. Most exam-prep tutors keep this in a spreadsheet or Notion doc between the classroom and the parent-facing recap.
  • No pre-loaded past-paper library. Koala Go doesn't ship past papers, question banks, or rubric printouts — those come from the exam boards themselves (Cambridge Assessment English, ETS, College Board, ACT, British Council) or from licensed third-party providers. You bring the material; the whiteboard hosts it. This is intentional (past-paper copyright + accuracy risk if we shipped stale versions), but it's a real setup step for the tutor.
  • iPad experience is rougher than desktop for annotation-heavy work. Marking up a past-paper PDF with a stylus on an iPad works, but the precision and drag-and-drop feel are noticeably better on a Mac / Windows laptop with a mouse or a graphics tablet. For exam-prep annotation specifically, a laptop is worth the small setup step even for students who normally use an iPad. See equipment and software for online tutoring for the tutor-side setup.
  • China connectivity is an infrastructure workaround, not a solve. Cambridge and IELTS have real exam-prep demand from mainland China, and Koala routes those families through our Hong Kong proxy (the China-routed room link). It works most of the time; connectivity is inherently constrained. For Chinese exam-prep students specifically, do a real tech check on the actual China link before you commit to the course. See teaching English online to students in mainland China.

The last two weeks — deadline-mode teaching

The final fortnight of an exam-prep course looks and feels different from every week that came before. What changes:

  • Content teaching stops. No new grammar, no new vocabulary lists, no new question shapes. If the student doesn't have it by week 11, they won't have it by exam day, and trying to fit it in raises anxiety without improving score.
  • Practice tests move to real conditions. Full-length, timed, at the same time of day as the real exam, in the same modality (paper or computer) as the real exam. If the real exam is at 9am and the student's practice tests have all been at 4pm, run at least two morning practice tests before the real day — cognitive performance is time-of-day sensitive.
  • Speaking practice moves to "no notes." Cambridge and IELTS speaking are unscripted; TOEFL Speaking gives you 15-30 seconds to prepare. In the last two weeks, cut off any bulleted-notes-in-front-of-you speaking practice. Have the student answer cold. Record. Review together. This is the fastest speaking-score gain in the whole course and it's specific to the deadline window.
  • Test-day logistics get explicit. Where's the test centre or the exam URL? What time do they need to be there or logged in? What ID? What can they bring? What can they NOT bring? Which browser for the computer-based version? What happens if their internet drops? An hour of "run through the test-day step-by-step" in the second-to-last lesson prevents the specific test-day panic that costs the student 20 minutes of the actual exam.
  • The parent conversation shifts to expectation management. Whatever the student scored on the last two practice tests is roughly what they'll score on the real exam, plus or minus a small variance. If those scores are below target, the parent needs to hear that in week 11, not on exam day. Better to have a hard week-11 conversation about the realistic outcome than a lost family after a disappointing result.
  • The last lesson is short and quiet. Lesson before exam day: 30-45 minutes, no new material, no long practice section. A short review of the test-day habits, a warm "you've done the work," a specific "here's what you're good at that you should trust yourself on." The night before the exam is not the time to raise anxiety with a full practice test.

Common failure modes

  • Overpromising in the trial lesson. The single most common exam-prep-tutor mistake. Setting an unrealistic target ("we'll get you to Band 8 in six weeks from a Band 6.5") produces a family that hires you and then leaves when the mid-course diagnostic doesn't match the promise. Set achievable targets in the diagnostic report, and revisit at the mid-course checkpoint if the arc looks off.
  • Skipping the diagnostic. Teaching a course from lesson 1 with no timed diagnostic is teaching blind. You'll spend the first three weeks realising the student's weakest section wasn't the one you assumed. The 90-minute diagnostic in lesson 1-2 is the highest-value part of the whole course.
  • Using non-official practice material. The exam boards publish real past papers, real sample tests, real practice interfaces. Third-party "practice tests" — even from big-name test-prep publishers — often skew easier or use question shapes the actual exam doesn't. Prep on official material; supplement with third-party only where the exam board hasn't published something.
  • Grading against the tutor's feel, not the rubric. "That felt like a Band 7" is not a Band 7. Take the rubric down from the exam board's site, print or bookmark it, and score against it every time. This is also what protects you when the parent later says "the practice tests said 6.5 but she got 6 on the real thing" — if you've been scoring to the rubric all along, the small variance is expected and defensible.
  • Never running a full-length timed practice test. Two-hour reading + writing + one-hour speaking + one-hour listening for a full IELTS is a lot of hours to burn, and lots of tutors skip it. Don't. The student needs to have experienced the endurance of a full session before exam day; the first time should not be in the exam.
  • Ignoring speaking practice because it's the section they're best at. Speaking is the section every student says they're best at and where actual speaking scores get lost. Record every speaking practice. Play it back. The gap between "how they feel about their speaking" and "what a rubric says about their speaking" is where most speaking-score gains come from.
  • Building a course that's 90% content, 10% test-taking habits. Test-taking habits — timing, question-shape recognition, "answer everything," "skim then commit" — recover meaningful score without teaching new content. Aim for 30-40% of course time on these, especially in the second half of the course.

When exam prep is the wrong tool for what the family actually wants

  • The student's underlying skill gap is much larger than the exam-prep window. A B1 English learner cannot prepare for C1 Advanced in three months, no matter how good the tutor is. In these cases, the right conversation with the family is "your child needs a year of general English at their level before an exam course makes sense" — you might lose the exam-prep booking and gain a longer general-tutoring engagement, which is a better outcome for both sides.
  • The parent wants exam prep for a "back-up plan" exam the student doesn't need. Not every high-schooler needs SAT prep, not every ESL child needs Cambridge YLE. Sometimes the exam is on the parent's plan more than the student's. Be honest about whether the prep is worth the student's time.
  • The student is genuinely burned out. An exam-prep course adds cognitive load. A student already saturated with school will produce a worse score after 12 weeks of extra tutoring than they'd have produced with rest. This is a hard conversation but a real one.
  • The exam has been discontinued or restructured. Sanity-check that you're prepping the current version of the exam — Digital SAT replaced paper SAT in 2024, TOEFL iBT was restructured in 2023, IELTS on Computer runs differently from paper IELTS. Prepping the wrong version is worse than not prepping.

A short decision framework for a new exam-prep student

  1. What exam, which version, when is the test date? If any of these is fuzzy, get it clear before quoting a course length. Different versions of the same exam have different question types, timings, and skills weightings.
  2. What is the current diagnostic score and the target? A specific number, on official material, taken under timed conditions in the first two lessons.
  3. Is the target realistic in the time available? One band (or 100 points, or a full grade level) is a large delta; more than one is usually not achievable regardless of tutor quality. Set the target you can hit; write it down; hit it.
  4. What's the cadence and package? Two lessons a week for 12-16 weeks is the standard shape (see how to structure lesson packages for the pricing side). Adjust for compressed or long-slow prep timelines.
  5. What's the platform stack? A shared whiteboard that takes PDFs, a cobrowser for the exam-board site, recording for speaking practice, recurring scheduling for the cohort, and a running lesson log. On Koala Go the PDF + cobrowser + recording combination needs the Pro tier ($25.99/mo monthly, $21.99/mo annual); the recurring-cohort schedule needs Scheduling Plus on Platinum ($49.99/mo monthly, $39.99/mo annual). One student's course typically pays for the subscription many times over — this is where the Pro upgrade pays.
  6. Have you set expectations with the parent in writing? The diagnostic report from lesson 2 should name the current score, the target, the plan, and the honest probability. In writing. This is the single most professional signal an exam-prep tutor gives.

If you'd like to try Koala Go for an online exam-prep course, the whiteboard, cobrowser preview, and small-group room all work on the Free tier — enough to run the diagnostic and lesson 1 of most exam-prep courses before deciding whether the Pro upgrade (which unlocks the PDF upload, unlimited cobrowser, and recording that a full course needs) is worth it. Open Koala Go at classroom.teachwithkoala.com, or write to koala@teachwithkoala.com with the specific exam and course length and we'll give you an honest read on whether Koala fits your particular workflow.
