GAMSAT Preparation: How to Study for the GAMSAT
To prepare for the GAMSAT: sit one timed section first, give most of your week to the section it exposes, and write essays that get marked.
Most candidates take three to six months. No fabricated cut-offs below — ACER publishes none.
One timed section tells you more about what to study than the rest of this page does.

What the GAMSAT actually is
ACER’s reasoning exam. It measures how you think under time pressure, not what you memorised.
Published ACER format. Confirm your own sitting on the official ACER GAMSAT website.
The longer answer — who runs it, who uses it, and what it is not
ACER runs it; universities in Australia, the UK and Ireland use it to select into graduate-entry medicine and allied health programs. It is not a content exam with a syllabus you can finish: nearly every question hands you what it wants you to use, and the difficulty is applying it quickly to unfamiliar material.
Do you need to study for it?
Yes — but the first move is not study, it is measure. Sit one timed section, then decide.
Two branches, not five. The reader asking this has not started yet.
Why “can you cram the GAMSAT?” is the wrong question
A test with no syllabus sounds like one you either can or cannot do. But pacing, essay structure and reading dense prose accurately are trainable, and that is where most candidates lose marks. What cannot be crammed is science you never learned.
- You have never sat a timed GAMSAT-style paper
- Sit one first, then decide. Almost nobody predicts their own pacing. One timed section teaches you more than a week of reading about the exam, and costs an afternoon.
- You have sat one, and you know which section hurt
- Study that section, on a schedule. The question is no longer whether to study but what. Give the section that cost you most the majority of your weekly hours, until a second attempt says otherwise.
How long to prepare
Three to six months is the usual range, depending on how much Section III you build from scratch.
Our recommended runways, not measured data. Let your first timed section move you between them.
What each runway assumes — and how to tell which one is yours
Total hours is the wrong unit: ten reviewed hours a week beat twenty unreviewed ones. Resitting assumes a real score to aim from, and one section to fix rather than three. A science background assumes Section III is revision, not new learning. Non-science assumes first-year biology and chemistry must be built before they can be reasoned with.
| Starting point | Runway | Weekly hours | What it assumes |
|---|---|---|---|
| Resitting, and you know your weak section | 6–10 weeks | 8–12 h | A real score to aim from, and one section to fix rather than three. |
| First sitting, science background | 3–4 months | 10–15 h | Section III is revision, not new learning; Sections I and II are the unknowns. |
| First sitting, non-science or working full time | 5–6 months | 6–10 h | First-year biology and chemistry must be built before they can be reasoned with. |
Our recommended runways, not measured data — no published study maps hours to GAMSAT scores.
The three sections & their timing
Two multiple-choice papers and one writing paper, sat on two days about three weeks apart.
What each section actually asks of you, and the format table
- Section I — Reasoning in Humanities & Social Sciences
- Passages, poems, cartoons and tables. No syllabus — it rewards careful reading and inference.
- Section II — Written Communication
- Two essay tasks on sets of short quotes — one socio-cultural, one reflective. The exam rewards argument and expression, not a 'correct' opinion.
- Section III — Reasoning in Biological & Physical Sciences
- Biology, chemistry and physics, weighted to the first two. It assumes first-year science but hands you most of what you need.
| Section | What it tests | Questions | Time | Format |
|---|---|---|---|---|
| Section I | Reasoning in Humanities & Social Sciences | 62 MCQ | 100 min | Multiple choice |
| Section II | Written Communication | 2 essays | 65 min | Two written tasks |
| Section III | Reasoning in Biological & Physical Sciences | 75 MCQ | 150 min | Multiple choice |

A week-by-week preparation shape
A 12-week block in four phases. The proportions matter more than any single week.
Front-loaded on learning, back-loaded on timing. Stretch or compress it — the order of the phases is what matters.
All 12 weeks, phase by phase
Our shape, not ACER's: front-loaded on learning, back-loaded on timing. The commonest way a plan fails is that timed work never starts — the first full-length attempt lands a fortnight out, with no room left to act on it.
| Weeks | Phase | A week's output |
|---|---|---|
| 1–3 | Foundations | 2 lesson blocks · 1 untimed question set · 1 essay |
| 4–7 | Build | 3 question sets · 1 timed section · 2 essays |
| 8–10 | Timed | 1 full mock · 2 timed sections · 2 essays |
| 11–12 | Taper | 1 timed section · 1 essay · review only |
Our 12-week shape. Stretch or compress it — the order of the phases is what matters.
How to practise so it counts
Practice moves your score only when it closes: attempt, review, then re-test a week later.
Close the loop weekly. An open loop is reading, not practice.
The three ways the loop breaks
The essay half needs a second reader: what you cannot see in your own writing is what it was like to read.
- Attempt — the failure
- Practising untimed, so you never rehearse the only condition the exam has.
- Review — the failure
- Reading the explanation, nodding, and moving on — recognition is not recall.
- Re-test — the failure
- Never returning, so the fix decays before the exam and you re-learn it in June.
How the score works
Three section scores plus an overall, usually weighted so Section III counts twice.
Melbourne, UQ and Notre Dame recompute an unweighted mean.
Scaled scores, the exceptions, and why Section III gets the attention
Scaled scores are not raw marks: ACER equates them so a score means the same difficulty-adjusted performance from sitting to sitting. It publishes no score-to-percentile table. Where the double weighting applies, a point in Section III moves your overall twice as far as a point anywhere else.
What counts as a good score?
Often the low-to-mid 60s. Many programs also set a per-section minimum near 50.
Cut-offs are set by each university, move every year and are rarely published.

Why there is no percentile table here
Until September 2026 this section mapped scaled scores to percentile bands. ACER publishes no such mapping; ours were estimates, and an estimate set in the grammar of a published statistic gets lifted into an answer box with its caption left behind. The ladder keeps the only two columns we can stand behind: the score, and what it means for an application.
| Scaled score | What it means for an application |
|---|---|
| 50 | The per-section minimum many programs set; below it a strong overall may not be read. |
| 55 | Around the middle of the candidate pool in most sittings. |
| 60 | Approaching competitive for a number of programs. |
| 65 | Competitive for most graduate-entry medicine programs. |
| 70+ | Strong across all three sections; rarely the limiting factor. |
Cut-offs are set by each university, move every year and are rarely published as fixed figures.
How hard is the GAMSAT?
Hard in one specific way: about two minutes a question, on material you have never seen.
The four demands, cheapest to dearest. A qualitative ordering, not a measurement.
The pace, in seconds — and what the curve deliberately does not say
Every figure here is division over ACER's published format. There is no published pass rate and no dataset of question demands, so the curve above carries a shape and no scale.
| Section | Items | Time | Per item |
|---|---|---|---|
| Section I | 62 questions | 100 min | 1 min 37 s per question |
| Section II | 2 essays | 65 min | 32 min 30 s per essay |
| Section III | 75 questions | 150 min | 2 min 0 s per question |
Arithmetic over the published format. Confirm your own sitting on the official ACER GAMSAT website.
- Recall
- Almost nothing. The stimulus usually gives you the facts.
- Comprehension
- Read a dense, unfamiliar passage accurately, once.
- Application
- Use a principle on material you have never seen.
- Reasoning under the clock
- All of the above, at the pace in the table.
The four demands above, in order — a qualitative ordering, not a measurement.
How to prepare effectively
Four principles separate preparation from busywork — and the essay has a reliable shape.
No single “correct” opinion — the exam rewards argument, examples and expression. Not affiliated with ACER.
The four principles, and where each one is worked
Train the clock, target the weak section, get essays marked, and review every mistake until you can re-answer it. All four are possible without paying anyone, and the lesson library is open with no login. Essays are marked by two independent AI Judges on a rubric we built from ACER's two published criteria.
- Introduction
- Frame the theme, stake a thesis.
- Body 1
- Claim, evidence, analysis.
- Body 2
- Develop or complicate it.
- Body 3
- Counterpoint, then resolve.
- Conclusion
- Synthesise, answer “so what?”

Three weeks that hold, and the hours in each
The pattern that fails is the one with no rest day: it survives three weeks, collapses in week six, and the restart costs more than the day off would have.

The last month, and the last week
The last month narrows: a final full mock, then repair, then essays, then taper.
Our recommended taper: volume falls as the sitting approaches, review rises. No full mock in the last three days.
Week by week: what to do, and what not to
| When | Focus | Do this | Not this |
|---|---|---|---|
| 4 weeks out | Last full mock | One complete timed mock, at the hour your real sitting starts. Two days reviewing it. | Starting a new topic. Four weeks consolidates a subject; it does not teach one. |
| 3 weeks out | Fix what the mock found | Three targeted sets on the two weakest areas the mock exposed, reviewed the same day. | Re-reading notes. If you cannot answer with them shut, you have not learned it. |
| 2 weeks out | Essays, and the clock | Two essays under the real per-essay budget, both marked, both re-planned before rewriting. | Writing more essays than you can review. An unmarked essay rehearses your habits. |
| 1 week out | Taper and confirm | One short timed set a day. Confirm venue, ID and start time. Sleep on schedule. | A full mock in the last three days — it costs rest and tells you nothing you can act on. |
Our recommended taper: volume falls as the sitting approaches, review rises.
Dates & the application calendar
Twice a year, around March and September, with results six to eight weeks later.
The GAMSAT costs AUD $568 to sit for the 2026 cycle; ACER has not published its 2027 fee.
Fees, and the dates that are published versus estimated
Late registration adds a fee, and some candidates qualify for a reduced one. Treat the 2026 figure as the last confirmed one, not next cycle's. Some 2027 dates are ACER-confirmed and some are pattern estimates — we label which is which rather than promote an estimate to a fact. Confirm your own sitting on the official ACER GAMSAT website.

Frequently asked questions
17 questions, answered. Every answer is on the page for search, and closed for the reader.
What is the GAMSAT?
The GAMSAT (Graduate Medical School Admissions Test) is a standardised exam administered by ACER. Universities in Australia, the UK and Ireland use it to help select applicants for graduate-entry medicine and other health-professional programs. It assesses reasoning and problem-solving rather than memorised facts.
What are the three sections of the GAMSAT?
Section I (Reasoning in Humanities and Social Sciences) tests comprehension of written and visual material. Section II (Written Communication) is two essay tasks. Section III (Reasoning in Biological and Physical Sciences) covers biology, chemistry and physics. Sections I and III are multiple choice.
How is the GAMSAT scored?
You receive a score for each section plus an overall score, commonly a weighted average that counts Section III twice as heavily as Sections I and II. Some universities apply their own weighting, so check how each program uses your scores.
What is a good GAMSAT score?
Competitive applicants often score in the low-to-mid 60s, and many programs set a per-section minimum near 50. Cut-offs move each year and differ by university, so treat any single number as a guide, not a guarantee.
How long should I study for the GAMSAT?
Most candidates prepare over roughly three to six months. What matters more than total hours is consistent timed practice, targeted work on your weak areas, and writing essays regularly with feedback.
How often is the GAMSAT held, and how long are results valid?
ACER typically offers the GAMSAT twice a year. Results can be used for up to four consecutive years in Australia, and two in the UK and Ireland. Confirm dates, fees and validity rules on the official ACER GAMSAT website.
Can you really prepare for the Section II essays?
Yes. Section II rewards clear structure, relevant examples and a coherent argument — all of which improve with practice and feedback. Aptavia marks your essays on a rubric we built from ACER's two published criteria so you can see exactly what to work on.
How much does the GAMSAT cost?
The GAMSAT costs AUD $568 to sit for the 2026 cycle. Late registration can add a further fee, and ACER offers reduced fees or bursaries for some eligible candidates. Fees change year to year, so confirm the current amount on the official ACER GAMSAT website.
How many questions are on the GAMSAT?
The current computer-based GAMSAT has 62 multiple-choice questions in Section I (100 minutes), two written tasks in Section II, and 75 multiple-choice questions in Section III (150 minutes). The older paper-based exam had more questions per section.
Is the GAMSAT computer-based?
Yes. Since 2024 the GAMSAT is computer-based, not paper. Section II (Written Communication) is sat from home via remote proctoring, while Sections I and III are taken at a test centre on a computer.
When is the GAMSAT held?
ACER runs the GAMSAT twice a year, in March and September. Registration opens several months ahead and closes weeks before each sitting, so check the official ACER GAMSAT site for the exact dates and deadlines for your sitting.
Is the GAMSAT hard?
The GAMSAT is hard mainly because it tests reasoning under tight time pressure rather than memorised content, so you cannot cram for it like a university exam. Most candidates find Section III's pace the toughest, and consistent timed practice is what makes it manageable.
What is a GAMSAT percentile?
Your GAMSAT percentile is the proportion of candidates you scored above, and it matters because many programs rank applicants against each other. ACER doesn't publish an official score-to-percentile table, and this guide no longer prints an in-house estimate of one — read the score ladder instead.
Can you resit the GAMSAT?
Yes — you can sit the GAMSAT as many times as you like. Results can be used for up to four consecutive years in Australia (two in the UK and Ireland), and most universities use your best or most recent score (check each program's policy), so many candidates sit more than once to improve.
GAMSAT vs MCAT — what's the difference?
They are different graduate-medicine entrance exams. The GAMSAT (ACER) is used in Australia, the UK and Ireland and rewards reasoning plus essay writing; the MCAT (AAMC) is used mainly in North America and is far more content-heavy. Sit whichever your target schools require.
Do I need a science background for the GAMSAT?
No — you don't need a science degree, but Section III assumes roughly first-year-university-level biology and chemistry (and some physics). Non-science applicants regularly succeed by building that foundational knowledge and focusing on the reasoning skills the exam actually rewards.
What should I study for GAMSAT Section III?
Section III draws on first-year-level biology, general and organic chemistry, and physics — but it tests how you apply them to unfamiliar data and experiments, not recall. Prioritise the high-yield core concepts (equilibrium, genetics, energetics, kinematics, organic mechanisms) and practise interpreting graphs, tables and novel scenarios under time.
