How GEMSAS Ranks You: GPA, GAMSAT and Preferences

What GEMSAS is

GEMSAS (the Graduate Entry Medical School Admissions System) is the centralised body that processes applications for most graduate-entry medical programs in Australia. You submit one application and rank your preferred universities; GEMSAS coordinates how you're assessed against each school's rules.

The three levers

Broadly, three things determine whether you're offered an interview and, later, a place:

• Your GPA — your grade point average, sometimes weighted so more recent study counts for more.
• Your GAMSAT score — the graduate admissions test, which some schools weight differently across its three sections.
• Your preferences and eligibility — the order you rank schools, plus category (such as domestic vs full-fee) and any quotas.

GPA: not always a simple average

Many schools use a weighted GPA rather than a flat average of every subject you've taken — for example, giving your most recent years more weight. The exact weighting varies by university and changes over time, so treat your raw GPA as a starting point and always confirm the current rule on the school's admissions page.

GAMSAT: weighted vs unweighted

The overall GAMSAT score ACER reports is weighted — Section III counts double: (Section I + Section II + 2 × Section III) ÷ 4. Some schools instead use an unweighted average that treats all three sections equally: (I + II + III) ÷ 3. The University of Melbourne is a well-known example of a school that uses the unweighted approach. Which one applies can meaningfully change where you sit, so check each school on your list.

Preferences and what you control

Preference order, category, and quotas all feed into outcomes, and much of this isn't something you can change close to application time. What you can control is your GAMSAT preparation, your interview performance, and choosing a realistic, well-researched preference list. Once you have an interview offer, your performance in the room is often the most improvable lever left — which is exactly what deliberate practice is for.

An important caveat

GEMSAS's exact formulas aren't fully published and differ between schools and years. Any calculator or guide — including ours — is an estimate, not a verdict. Use official university admissions pages and the current GEMSAS admissions guide as your source of truth.
