For the Australian GAMSAT® · March 2027 sitting
Start with 40 free exam-style MCQs — 20 from Section 1 and 20 from Section 3 — plus two timed Section 2 essays with AI feedback. No sign-up needed to start the questions.
Which change would shift the oxygen–haemoglobin dissociation curve in the same direction as lowering blood pH from 7.4 to 7.2?
Why B
Lower pH reduces haemoglobin’s affinity for oxygen (the Bohr effect), shifting the curve right. 2,3-BPG binds deoxyhaemoglobin and does the same.
The free set covers every section, so you can see where you stand before you spend anything.
The Graduate Medical School Admissions Test (GAMSAT®) is the entry test for graduate-entry medicine in Australia, and for some graduate-entry dentistry, optometry, pharmacy and other health programs. Medical schools in the UK and Ireland use it too.
It is developed and run by the Australian Council for Educational Research (ACER) on behalf of GEMPASS Australia, the consortium of graduate-entry schools. It runs twice a year, in March and September, and there is no limit on how many times you can sit it.
GAMSAT is a reasoning test, not a memory test. It assesses how well you read and interpret unfamiliar material, think critically and write clearly. You don’t need a science degree to sit it, but Section 3 assumes roughly first-year university biology and chemistry and senior-school physics.
The test is computer-based. Section 2 (writing) is sat at home under remote supervision in its own test window. Sections 1 and 3 are sat together on one day at a test centre, usually a few weeks later. If you live more than three hours’ drive from a test centre, or in a country without one, you can apply to sit all three sections remotely.
Every multiple-choice question has four options, and no marks are deducted for a wrong answer — so never leave one blank. Sections 1 and 3 are sat together, with a 30-minute break between them.
Section 1
Passages of prose, poetry, cartoons, tables and extracts from plays or reports, each followed by several questions. You are tested on interpretation — tone, attitude, implication, the shape of an argument — not on prior knowledge.
How to practise: read widely and quickly, then check exactly which words in the passage support your answer.
Section 2
Two writing tasks, each giving you four statements on a common theme. Task A deals with socio-cultural issues; Task B with more personal and social ones. Markers judge the quality of your thinking and your control of language — not whether your opinions are “correct”. Spelling and punctuation slips don’t cost marks.
How to practise: write to time, then rewrite. Don’t memorise essays — ACER says they generally score poorly, and every response is checked for plagiarism.
Section 3
Units built on data, diagrams and short passages: 40% chemistry, 40% biology and 20% physics, mixed through the section. Most of what you need is in the stimulus; the test is whether you can use it — rearrange an equation, read a graph, follow a mechanism.
How to practise: do timed units, and redo the maths by hand without a calculator — none is allowed.
You get a score for each section and an overall score, each on a scale of 0 to 100. These are scaled scores, not percentages: ACER adjusts for differences between test versions so scores are comparable from sitting to sitting.
The overall score is a weighted average in which Section 3 counts twice, so a point gained in Section 3 is worth twice as much as a point in Section 1 or 2. Your results also show your approximate percentile against others in the same sitting.
There is no pass mark. Universities set their own cut-off scores each year, and some use the scores in other ways, so check each school’s admissions guide. Results are valid for four years in Australia, and two years in the UK and Ireland.

GAMSAT® runs twice a year, in March and September. Registration closes weeks before each test, and late fees apply — always confirm dates on the official site.
Every set looks like the real thing: one stimulus, then two to five questions. Do a unit on the tram, or a timed block at your desk.
Each question has a full explanation plus a note on every wrong option, so you learn the trap as well as the answer.
Questions are tagged by concept. You see your accuracy per concept — always with how many questions it is based on — and a short note to revise from.
Timed Section 2 essays with structured feedback on thought and content, and on organisation and expression. Clearly labelled as AI feedback.

Yes. The 40 MCQs work without an account. You only need a free account to save your progress and get AI feedback on the two practice essays.
No. Every question is original, written for GradMedMentor. ACER produces the only official GAMSAT® practice materials, and we suggest you use them too.
No. Section 3 assumes roughly first-year university biology and chemistry and senior-school physics. If your background is in the humanities, start with the free Section 3 set to see where you stand.
There’s no magic number. Read every explanation, go back over the questions you got wrong, and switch to timed sets as the test gets closer.
An AI model reviews your essay against criteria based on what ACER says Section 2 markers look for. You get a score for thought and content and for organisation and expression, plus specific strengths and things to work on. It is a practice tool, not an official GAMSAT® mark. ACER’s own practice essay tool returns a score but no written feedback; ours tells you what to change.
Yes — it is designed for phones first. Units are short, and you can pick up where you left off on any device.
