UCAT vs GAMSAT: Which Test Do You Need?

If you’re aiming for a career in medicine, one of the earliest questions you’ll face is: which admissions test do I need to sit? For many aspiring doctors in Australia, the answer comes down to two options — the UCAT or the GAMSAT. These tests serve different entry pathways, attract different applicants, and require very different preparation strategies. Understanding which one applies to you is an essential first step.

What Is the UCAT?

The University Clinical Aptitude Test (UCAT) is used for entry into undergraduate and early-entry medical programs. It is primarily designed for Year 12 students and recent school leavers who are applying directly to a medical degree from secondary school.

The UCAT is a computer-based test sat annually, typically between July and September in the year of application. It does not test curriculum knowledge — instead, it assesses a range of cognitive and behavioural aptitudes considered important for healthcare professionals.

UCAT Test Format

The UCAT consists of five subtests:

• Verbal Reasoning — assessing the ability to critically evaluate written information
• Decision Making — testing logical reasoning and judgement under uncertainty
• Quantitative Reasoning — evaluating numerical problem-solving skills
• Abstract Reasoning — measuring the ability to identify patterns and relationships
• Situational Judgement — assessing how candidates respond to realistic professional scenarios

The total test time is approximately two hours, and results are used alongside academic scores (ATAR or equivalent) and, in some cases, interviews.

What Is the GAMSAT?

The Graduate Medical School Admissions Test (GAMSAT) is used for entry into graduate-entry (postgraduate) medical programs. It is designed for graduates or final-year undergraduate students who are applying to a medical degree after completing a prior university qualification.

The GAMSAT is offered twice a year — typically in March and September — and is administered by ACER (Australian Council for Educational Research). It is a significantly longer and more demanding test than the UCAT, reflecting the higher academic baseline expected of graduate applicants.

GAMSAT Test Format

The GAMSAT is divided into three sections:

• Section I: Reasoning in Humanities and Social Sciences — interpreting and analysing written and visual material across a range of disciplines
• Section II: Written Communication — producing two extended written responses to stimulus material
• Section III: Reasoning in Biological and Physical Sciences — applying scientific reasoning across biology, chemistry, and physics

The full test runs for approximately five and a half hours. A strong performance in Section III is particularly important, as it carries the most weight in most universities’ scoring formulas.

Key Differences Between the UCAT and GAMSAT

While both tests are used for medical school admissions, they differ in several important ways.

Entry Pathway

The UCAT is for undergraduate medicine — you apply straight from school into a five- or six-year medical degree. The GAMSAT is for graduate-entry medicine — you apply after completing (or nearly completing) a bachelor’s degree, entering a four-year medical program.

Timing in Life

Most UCAT candidates are 17–18 years old and in their final year of secondary school. GAMSAT candidates are typically in their early-to-mid twenties, having already completed an undergraduate degree.

Test Format and Difficulty

The UCAT is shorter and does not require prior scientific knowledge. The GAMSAT is considerably longer, requires a solid grounding in biology, chemistry, and physics, and demands strong written communication skills. The cognitive demands of both tests are high, but in different ways.

Preparation Demands

UCAT preparation typically involves practising aptitude-style questions, developing speed and accuracy, and familiarising yourself with the test interface. GAMSAT preparation often requires months of content review — particularly in the sciences — alongside practice with extended writing.

Score Validity

UCAT scores are valid for the application cycle in which they are obtained. GAMSAT scores are valid for two years, giving candidates more flexibility to apply across multiple cycles.

Can You Sit Both Tests?

Yes — and for some applicants, sitting both tests makes sense. If you are applying to both undergraduate and graduate-entry programs simultaneously, or if you are a final-year undergraduate student who also sat the UCAT during Year 12, you may find yourself holding scores for both.

Some applicants who are unsuccessful through the undergraduate pathway choose to pursue a different bachelor’s degree and later sit the GAMSAT to apply through the graduate-entry route. In this case, a prior UCAT score is no longer relevant, but the experience of sitting a high-stakes admissions test can be valuable preparation.

How to Decide Which Path Suits You

Choosing between the UCAT and GAMSAT ultimately comes down to your current stage of study and your preferred entry route. Here is a practical framework to help you decide.

Are you in Year 12 or a recent school leaver?

If you are currently completing secondary school or have recently finished, the UCAT is almost certainly the relevant test. Undergraduate medicine programs in Australia use the UCAT as part of their selection process, and this is the most direct route into medicine from school.

Have you already completed (or nearly completed) a bachelor’s degree?

If you hold a degree or are in your final year of undergraduate study, the GAMSAT is the appropriate test. Graduate-entry programs do not use the UCAT, and your undergraduate academic record will also form part of your application.

What is your academic background?

The GAMSAT’s Section III requires a working knowledge of biology, chemistry, and physics. If your undergraduate degree is in a non-science field, you will need to invest significant time in science preparation. If you have a science background, this section may be more accessible — though it still requires dedicated practice.

What are your lifestyle and timing considerations?

Undergraduate medicine is a longer degree (typically five to six years), but you enter the profession earlier. Graduate-entry medicine is shorter (typically four years), but you spend additional years completing an undergraduate degree first. Consider your financial situation, personal circumstances, and long-term goals when weighing these timelines.
