EXAM COMPARISON
Choosing between the UCAT and GAMSAT is one of the first big decisions on the path to medical school in Australia. The two exams test fundamentally different skills and open doors to different programs. Here is a clear, side-by-side breakdown to help you decide.
The UCAT (University Clinical Aptitude Test) is a two-hour, computer-based exam consisting entirely of multiple-choice and drag-and-drop questions across four subtests: Verbal Reasoning, Decision Making, Quantitative Reasoning, and Situational Judgement. Abstract Reasoning was removed from the exam in 2025. It is designed to assess cognitive aptitudes rather than academic knowledge and is taken once per year, typically between July and August for the ANZ cycle.
The GAMSAT (Graduate Australian Medical School Admissions Test) is a significantly longer exam, running approximately five and a half hours across three sections. Section I covers reasoning in the humanities and social sciences, Section II is a written communication task (two essays), and Section III tests reasoning in biological and physical sciences. Unlike the UCAT, the GAMSAT draws heavily on science knowledge, particularly chemistry, biology, and physics at a first-year university level.
In practical terms, the UCAT rewards speed and pattern recognition under time pressure, while the GAMSAT rewards deep scientific reasoning and the ability to construct written arguments. Your natural strengths and academic background often determine which exam plays to your advantage.
The UCAT is primarily used for undergraduate-entry medical programs. Universities that require or accept the UCAT include the University of New South Wales, Western Sydney University, the University of Adelaide, the University of Newcastle, Curtin University, Charles Darwin University, and several others. These programs typically admit students directly from Year 12 or as school leavers.
The GAMSAT is the standard entry exam for graduate-entry medical programs. Universities such as the University of Melbourne, the University of Sydney, Flinders University, the Australian National University, and Deakin University use the GAMSAT as part of their admissions process. Some universities, like the University of Queensland, accept either the GAMSAT or the MCAT.
A small number of students sit both exams to maximise their options. This is a viable strategy if you are applying to both undergraduate and graduate programs, but it requires separate preparation timelines because the exams test quite different skills.
UCAT preparation focuses on building speed, accuracy, and familiarity with specific question types. Because the exam does not test learned content, preparation revolves around practising with large question banks, learning time-management strategies, and reviewing worked solutions. Most students prepare for four to eight weeks. The emphasis is on doing hundreds of timed questions rather than reading textbooks.
GAMSAT preparation is typically a longer process, often spanning three to six months. Section III requires a solid foundation in first-year university science, so students without a science background may need to study biology, chemistry, and physics content before they even begin practising exam-style questions. Section II requires essay-writing skills, which benefit from regular practice and feedback.
If you are finishing Year 12 and want to enter medicine as an undergraduate, the UCAT is your path. It does not require university-level science knowledge, so students from any subject background can perform well with the right preparation strategy. Students who are quick thinkers and enjoy logic puzzles tend to find the UCAT plays to their strengths.
If you already hold a bachelor's degree or are completing one, the GAMSAT is likely the exam you need. It is particularly well suited to students with a science background, although non-science graduates do succeed — they just need to invest more time in Section III preparation. If you enjoy writing and have strong analytical reading skills, Section I and II can become real strengths.
There is no objectively easier exam. The UCAT is shorter but intensely time-pressured; the GAMSAT is longer but gives more time per question. The best choice depends on your educational stage, your target universities, and your natural aptitudes.
FREQUENTLY ASKED QUESTIONS
Yes. The UCAT ANZ testing window runs from July to August, while the GAMSAT is typically held in March and September. There is no rule preventing you from sitting both, and doing so widens the range of programs you can apply to. Just be aware that preparing for both simultaneously requires careful time management because the exams test different skills.
Neither exam is objectively harder — they are difficult in different ways. The UCAT challenges you with extreme time pressure and unfamiliar reasoning formats. The GAMSAT challenges you with deep science content, essay writing, and a five-and-a-half-hour test day. Students with strong science backgrounds often find the GAMSAT more predictable, while students who excel under time pressure may prefer the UCAT.
No. Each university specifies which exam it accepts, and there is no general preference for one over the other. Your choice of exam is dictated by the entry pathway (undergraduate vs graduate) and the specific universities you are targeting. Some programs are UCAT-only, others are GAMSAT-only, and a few accept either.
