The GAMSAT does not reward how much you have memorised. It rewards controlled reasoning on material you have never seen, sustained across 5 hours 15 minutes. This guide sets out a study plan that reflects that: diagnose your reasoning first, build only the assumed knowledge you are missing, then practise under real timing and review by error type.
The exam has three sections. Section I is reasoning in humanities and social sciences: 62 questions in 100 minutes on written, visual and data stimulus. Section II is written communication: two essays in 65 minutes total. Section III is reasoning in biological and physical sciences: 75 questions in 150 minutes, roughly 40% biology, 40% chemistry and 20% physics. Almost every item supplies the information you need — the difficulty lies in extracting it correctly under time pressure.
A full section-by-section breakdown, including question types and the assumed knowledge list, is on our GAMSAT syllabus page.
Weeks 1–2
Sit a timed diagnostic under exam conditions before you touch a textbook. Most candidates lose marks to a small number of repeated reasoning faults — reversing a stated cause, widening a claim beyond the stimulus, or answering a question the passage never asked. Until you can name your own faults, extra practice just rehearses them. Record your section-by-section accuracy, your average time per item, and the two or three error types that appear most often.
Weeks 3–8
Section III assumes first-year biology and chemistry and Year 12 physics. It does not reward memorising beyond that. Work from the assumed-knowledge list rather than a university syllabus: cell biology, genetics, metabolism, acid–base, equilibrium, organic functional groups and reaction logic, stoichiometry, kinematics, energy, waves and electricity. Study each topic to the point where you can read an unfamiliar graph or reaction scheme and reason from it — not to the point where you can recite it.
Weeks 3–8 (parallel)
Section I is comprehension under pressure across essays, poetry, cartoons and data. Read argumentative non-fiction daily and, for each piece, write one sentence stating the author's claim and one naming the evidence they rely on. This is the exact operation the exam tests. Poetry and cartoons reward the same discipline: identify the tension the piece sets up before you look at the options.
Weeks 6–12
Section II is written communication: two essays, 65 minutes total including reading time. Quality comes from a controlled thesis developed with specific evidence, not from volume. Write to time, then mark against the criteria that actually count — thought and content, organisation and expression, and the quality of the language. An essay you never review teaches you nothing; a marked essay with one concrete change to carry into the next one moves your score.
Final 6 weeks
The GAMSAT is 5 hours 15 minutes of working time: 100 minutes for Section I (62 questions), 65 minutes for Section II (two essays), and 150 minutes for Section III (75 questions). Stamina and pacing are separate skills from content. Sit complete papers under strict timing, resist checking answers mid-paper, and only then review. Aim for one full paper a fortnight, rising to one a week in the last month.
Every week
The highest-yield hour of the week is the review hour. For every wrong answer, write down which reasoning step failed rather than what the right answer was. Group them. When you see the same fault three times, drill that fault specifically. This is the single habit that separates candidates whose scores climb from candidates who plateau at the same band for two sittings.
Most candidates need three to six months of consistent work. Non-science backgrounds typically need closer to six months because Section III assumes first-year biology and chemistry. Ten to fifteen focused hours a week over that period is far more effective than a compressed six-week sprint, because reasoning habits change slowly.
Yes. Section III tests reasoning applied to supplied information more than recall, so the assumed knowledge is bounded: first-year biology and chemistry and Year 12 physics. Give yourself extra lead time, learn topics through problems rather than lecture notes, and prioritise chemistry and biology, which carry roughly 40% of the section each.
There is no threshold that guarantees a score. A candidate who does 300 questions and reviews every mistake by error type will usually outperform one who does 2,000 and reviews none. Practise enough to meet each question type repeatedly, and spend at least as long reviewing as answering.
Diagnose first, build only the assumed knowledge you are missing, practise under timing, and review by reasoning fault. Any approach that skips the last step tends to produce a plateau, because it treats every wrong answer as an isolated event rather than an instance of a repeated pattern.
Gamsat Prep runs the plan above for you: an adaptive diagnostic that names your reasoning faults, rationalised practice questions mapped to those faults, GAMSAT-style timed mocks, and AI essay marking against the Section II criteria.
