GAMSAT results explained

ACER releases March results in late May and September results in mid-November — roughly two months after the multiple-choice sitting. ACER-official ACER does not publish an exact calendar date in advance, and we do not estimate one.

You are notified by email and read the result online through your ACER account. No hard copy of the Statement of Results is sent, and only one Statement is issued per test taker per cycle. Statements stay accessible in your account for four years, which is a retention period rather than a validity period — conflating the two is the likely origin of the widespread confusion about how long a score lasts.

Four scores, each on a scale of 0 to 100: one for each section and one overall. ACER states in terms that “these are not percentage marks”. ACER-official

A scaled score of 60 does not mean you answered 60% of the questions correctly. Raw marks are transformed onto a common scale so that papers of different difficulty are comparable, and the raw percentage corresponding to a given scaled score changes between sittings. ACER does not publish that relationship, and no third party can reconstruct it.

Your percentile compares you only with the people who sat the same GAMSAT as you, and no university uses it. ACER-officialACER states: “The universities will consider your Section and Overall Score, not your percentile ranking. The universities will set their own cut-off scores from year to year.”

Two practical consequences. First, an identical score maps to different percentiles in different sittings — transcribed charts put an overall 63 at about the 69th percentile in March 2022 and about the 74th in March 2024. Second, the chart covers the overall score only; ACER does not supply section percentiles, so every section percentile you see anywhere is modelled, including ours.

Four years in Australia, two years in the UK and Ireland. ACER-officialThis is the fact most often reported wrongly, because it is not a single number. Scores from different sittings are directly comparable, so an older result is not a weaker one — it simply expires sooner in some markets than others.

Do not confuse validity with retention. Your Statement of Results stays in your ACER account for four years regardless of country. That is document access, not eligibility.

ACER offers no remark of any component, including Written Communication. ACER-officialIts stated reason is that “results are released only after careful calculation and extensive checking”. It adds that it “cannot provide any additional information on scores or the scoring process”, and that no right of inspection is vested in a test taker.

In practice that means there is no route to challenge a Section 2 mark you disagree with, no breakdown of which questions you got wrong, and no discussion of the scaling applied to your paper. If your result is not what you expected, the only available response is a decision about the next sitting — which is worth thinking about carefully.

Separately, ACER can withhold or cancel a score for a policy breach. The four triggers it lists are exposure to GAMSAT content whether intended or not, contradictory performance across parts of the test, abnormal answer patterns, and atypical performance across sittings. ACER explicitly warns that attending a coaching course where real test content is shown puts your score at risk — one of the reasons every question on this site is original.

There is no pass mark, because GAMSAT is a ranking instrument, not a test you pass. Universities set their own cutoffs annually, and those move with the strength of the applicant pool. The closest thing to a benchmark in the literature is the typical entry score: an overall of at least 60 with at least 50 in every section, achieved by 36.9% of candidates in the last measured cohort Peer-reviewed.

The scale runs to 100. In practice, overall scores above 80 are reached by roughly the top 0.1% of candidates, and the peer-reviewed analysis of 2005–2014 sittings found that section scores “rarely exceed 85” Peer-reviewed. Candidates have reported individual section scores of 100, but ACER publishes no maximum and we cannot resolve that tension from public sources.

One further piece of ACER guidance is useful when comparing results: a five-mark difference “anywhere on the scale, always represents the same change in ability”, but moving from 80 to 85 is typically harder than moving from 50 to 55.

Section 3, in most cases. It carries double weight in ACER’s overall and has the widest spread of the three sections, so it moves the overall number further than either of the others. It is also worth knowing that the correlation between Section 2 and Section 3 performance is very low — essay ability and science reasoning are close to independent, so a weak Section 2 alongside a strong Section 3 is an ordinary result rather than a contradiction.

GAMSAT runs across two sittings approximately three weeks apart. Written Communication is remote-proctored; Sections 1 and 3 are sat at a test centre.

That matters for interpreting your result: the two multiple-choice sections and the essays were sat weeks apart, under different conditions, one of them remote-proctored. Sections 1 and 3 also include unscored trial questions, which is one reason no practice test — ours included— can convert a raw mark into a predicted GAMSAT score.
