GAMSAT Preparation Guide
Preparing for the Graduate Medical School Admissions Test — sections, strategies, and how to balance prep with your degree.
What Is the GAMSAT?
The Graduate Medical School Admissions Test (GAMSAT) is the primary admissions test for graduate-entry Medicine and Dentistry programs at most Australian universities. Unlike the UCAT, which targets Year 12 students, the GAMSAT is designed for people who have already completed or are completing a Bachelor degree in any discipline.
The GAMSAT is held twice each year, in March and September. It is a demanding full-day exam lasting approximately five and a half hours across three sections. Your overall score is reported out of 100 as a weighted average. Results are valid for two years, giving you flexibility in when you apply.
Anyone applying to graduate-entry medical schools through the GEMSAS centralised application system will need a GAMSAT score. You do not need a science degree to sit the exam or to gain admission, but Section III does favour applicants with a science background. Non-science graduates can and do perform well, though they typically need to invest significant time in self-studying the relevant science content.
The Three Sections
Section I: Reasoning in Humanities and Social Sciences
Tests your ability to interpret poems, prose extracts, cartoons, and other stimulus material. Questions assess argument identification, inference drawing, and evaluation of reasoning. Despite the name, you do not need a humanities background — the section rewards careful reading and logical thinking rather than specific subject knowledge.
Section II: Written Communication
Requires you to produce two extended written responses to sets of quotations or thematic prompts. You must construct coherent, well-argued essays that demonstrate clear thinking and effective communication. One task typically invites a reflective or personal response, while the other requires argumentative or analytical writing. Essays are scored by human markers.
Section III: Reasoning in Biological and Physical Sciences
The science-heavy section covering chemistry (including organic chemistry), biology (cell biology, genetics, physiology), and physics (mechanics, optics, electricity). Most questions require knowledge at approximately first-year university level. Questions are stimulus-based, presenting experimental data or scientific scenarios that require both knowledge and reasoning to answer.
Overall Score Calculation
Your overall GAMSAT score is a weighted average of the three sections. Section III carries double the weight of Sections I and II, reflecting the importance of scientific reasoning for medical study.
Overall GAMSAT Score Formula
(S1 x 1 + S2 x 1 + S3 x 2) / 4
This means a strong Section III score has the greatest impact on your overall result. However, do not neglect Sections I and II — competitive applicants tend to perform consistently across all three sections.
Preparation Timeline
How early you should start depends primarily on your science background. Science graduates can often prepare effectively in three to six months, while non-science graduates may need six to twelve months to cover the Section III content from scratch.
Foundation building (non-science students)
If you do not have a science background, begin self-studying first-year chemistry, biology, and physics. Use university textbooks and online lectures to build foundational knowledge. This long lead time is essential for covering the breadth of content in Section III.
Start structured preparation
Begin a regular study schedule covering all three sections. Science students can start here. Complete a diagnostic practice test to identify strengths and weaknesses. Allocate study time proportionally, with the heaviest emphasis on Section III.
Intensive practice
Increase practice intensity. Complete full-length practice exams under timed conditions. Refine essay structures for Section II. Continue reading broadly for Section I. Focus on weak areas identified in your diagnostic and practice tests.
Final preparation
Taper new content learning and focus on consolidation, timed practice, and exam technique. Complete at least two full-length mock exams under realistic conditions. Review commonly tested concepts and ensure you are comfortable with the exam format and timing.
March or September sitting
The GAMSAT is held twice each year. The March sitting uses results for the current year's application cycle, while the September sitting can also be used. Choose the sitting that best aligns with your preparation timeline and GPA strategy.
Section-by-Section Strategy
S1 Section I: Reasoning in Humanities and Social Sciences
This section rewards broad reading habits developed over time. Read novels, poetry, opinion columns, philosophical essays, and social commentary regularly. Practise identifying the core argument in a piece of writing and evaluating whether the reasoning holds up. Focus on understanding tone, subtext, and the author's purpose. This section is very difficult to cram for — students who read widely throughout their degree tend to perform well naturally.
S2 Section II: Written Communication
Develop two or three flexible essay structures that you can adapt to different prompts. Read editorials and opinion pieces to observe how professional writers build arguments. Practise writing full essays under timed conditions at least once a week. Seek feedback from peers, tutors, or mentors, focusing on logical structure, clarity, and quality of argument rather than word count. Avoid overly formulaic writing — markers value genuine insight and thoughtful engagement with the prompt.
S3 Section III: Reasoning in Biological and Physical Sciences
This is where most preparation time should be directed, particularly if science is not your background. Focus on general chemistry, organic chemistry, human biology, and physics. First-year university textbooks are pitched at the right level. Work through practice problems to build both understanding and speed. Learn to interpret graphs, experimental results, and scientific data. Even science graduates benefit from systematic revision, as the content range is broad.
GAMSAT vs UCAT: Key Differences
The GAMSAT and UCAT serve different pathways into medicine and test fundamentally different things. If you are deciding between undergraduate and graduate entry, or considering both options, understanding these differences is important.
| Feature | UCAT | GAMSAT |
|---|---|---|
| Target applicants | Year 12 school leavers | University graduates or final-year students |
| Duration | ~2 hours | ~5.5 hours (full day) |
| Content tested | Cognitive aptitude and reasoning | Knowledge + reasoning (especially science) |
| Score validity | 1 year (single cycle) | 2 years |
| Sittings per year | Once (July) | Twice (March and September) |
| Science knowledge | Not required | First-year university level required |
| Writing component | None | Two essays (Section II) |
| Pathway | Undergraduate entry medicine | Graduate entry medicine |
Balancing GAMSAT with Your Degree
One of the biggest challenges of GAMSAT preparation is fitting it alongside your university coursework. Unlike the UCAT, which Year 12 students prepare for alongside school, the GAMSAT demands study time from candidates who already have a full university workload. Here are strategies that successful candidates use:
Protect your GPA
Medical schools evaluate both your GPA and GAMSAT score. A strong GPA with a moderate GAMSAT score can still be competitive. Never sacrifice your grades to focus exclusively on GAMSAT preparation — this is counterproductive.
Consider your course load
Some students take a lighter course load in the semester before their GAMSAT sitting to free up study time. Others study alongside a normal load but start preparation earlier. Choose the approach that does not compromise either goal.
Use your degree strategically
If possible, choose electives that complement GAMSAT preparation. Science electives help with Section III, while humanities and writing-intensive subjects develop skills for Sections I and II. Your degree work can double as GAMSAT preparation.
Plan around assessment periods
Map out your university assessment schedule and GAMSAT study plan side by side. Avoid scheduling your heaviest GAMSAT preparation during weeks with major assignments or exams. Build in buffer weeks for unexpected workload spikes.
After the GAMSAT
Applications to graduate-entry medical schools go through GEMSAS (Graduate Entry Medical School Admissions System), a centralised system where you rank your university preferences. Selection typically combines your GPA, GAMSAT score, and interview performance, with the weighting varying by institution.
Your GPA is calculated by GEMSAS using a standardised methodology that weights later years of your degree more heavily than earlier years. This means strong performance in your final year can significantly improve your competitiveness, even if your earlier grades were not outstanding.

Strong GAMSAT score
If your score is competitive (generally 60+), focus on maintaining your GPA and preparing for interviews. Research which universities weight the GAMSAT most heavily and align your preferences accordingly.
Below the competitive range
You can re-sit the GAMSAT at the next available sitting. Check each university's policy on score usage — some accept your most recent score, others your highest, and some use an average. Your score remains valid for two years, so you have time to re-sit strategically.
