How GAMSAT Scoring Works
The Graduate Medical School Admissions Test (GAMSAT) is a three-section exam by ACER that assesses your capacity for graduate-entry medical study. Understanding exactly how the scoring works is critical - a few points can mean the difference between an interview offer and rejection.
Each section is scored individually on a scale that typically ranges from around 40 to 90+, with most competitive applicants scoring between 55 and 80. But the raw section scores aren't what matter most - it's the weighted overall score that universities use.
The Weighted GAMSAT Formula
The section names are Section 1 (Reasoning in Humanities and Social Sciences), Section 2 (Written Communication) and Section 3 (Reasoning in Biology and Physical Sciences). Most Australian medical schools use a weighted formula where Section 3 counts double:
This means Section 3 (Biological and Physical Sciences) has an outsized impact on your overall score. A student scoring 50/70/80 across Sections 1/2/3 would have a weighted score of (50 + 70 + 160) / 4 = 70.0, while someone scoring 80/70/50 would get only (80 + 70 + 100) / 4 = 62.5 - despite having the same raw total.
For a student with a 7.0 GPA, a GAMSAT of 72 is highly competitive - but 67 could make them ineligible at almost every medical school. Just 5 points separates success from rejection.
The Combo Score - GAMSAT + GPA
Your GAMSAT score is combined with your GEMSAS GPA to produce a "Combo" score. This is the primary screening metric used by most Australian medical schools to decide who gets an interview:
Student A - Competitive Profile
GEMSAS GPA: 6.95 | GAMSAT: 75
(6.95 / 7) + (75 / 100) = 0.993 + 0.750
Combo: 1.743 - Highly competitive for most schools
Student B - Below Threshold
GEMSAS GPA: 6.75 | GAMSAT: 66
(6.75 / 7) + (66 / 100) = 0.964 + 0.660
Combo: 1.624 - Unlikely to receive an interview at most schools
The average minimum combo for Australian postgraduate medical schools is around 1.68. Student A is competitive. Student B is not - at most universities. There are important exceptions (see our article on university-specific exceptions).

How Improvable Is Each Section?
- Section 1 (Humanities): The most resistant to practice. Rarely improves more than 5 points over 6 months. If you haven't been an active reader, start now - there are no shortcuts.
- Section 2 (Writing): By far the most coachable. Students have moved from ~50 to 75+ in 6 months of targeted preparation. This is the highest-yield investment you can make. Try my free GAMSAT S2 practice tool.
- Section 3 (Sciences): Rewards consistent grinding. A typical improvement trajectory is 50 -> 55 -> 60 -> 65 across sittings as fundamental skills develop.
University-Specific Exceptions
Not every university uses the standard combo threshold. The University of Sydney, for example, dropped MMIs entirely and uses a GAMSAT-only formula that heavily weights Sections 1 and 2. The University of Wollongong uses CASPer instead of the combo for ranking. Observed applicant outcomes from 2024-2025 include Notre Dame interview invitations with combos as low as 1.56. Notre Dame does not publish this figure; it is not university policy, is not guaranteed, should not be relied upon, and can change at any time.

The combo score is one half of the equation. The other half is what comes next - interviews, CASPer, university-specific quirks. For the end-to-end picture, read the complete guide to getting into medicine in Australia.
