GPA and GAMSAT calculator

GEMSAS publishes one methodology document and then lets each medical school override parts of it. The shared skeleton runs like this.

1. Identify the key degree.The most recently completed eligible qualification inside the school’s currency window. Recognised bachelor degrees of three years or more, and completed standalone Honours years, are accepted everywhere; postgraduate qualifications vary by school.
2. Convert every result to the 7-point scale. Where an official percentage mark exists, Column A of the conversion table is used. Otherwise the letter column matching the awarding institution applies.
3. Bucket subjects backwards into GPA years. A GPA year is 1.0 FTE — one year of full-time study. It is not a calendar year and not a level of study. GEMSAS’s own example: if a full-time load is eight subjects of six credit points, a GPA year is 48 credit points, even where those credits were earned across two or more calendar years.
4. Average each GPA year.This is the one step GEMSAS does not fully specify — see the assumptions panel above.
5. Handle ungraded subjects. A passed ungraded subject fills FTE but contributes no grade point. A failed one is treated as a fail. Each school sets a minimum of graded study per GPA year, below which the year is disregarded entirely.
6. Apply the school’s year weighting. All five variants are listed below.
7. Apply bonuses afterwards. GEMSAS is explicit that bonus points for additional study are not included in the base GPA. They are added later, and only at schools whose selection process uses them.

Two rules cut against the grain and are worth knowing. Where you have more than 3 FTEof eligible study, only the most recent 3 FTE is used — at every school except UQ. Where you have less than 3 FTE, the shortfall is made up from the next most recent eligible qualification, which is how a one-year Honours degree becomes a final year sitting on top of two years of the preceding bachelor.

When a block of concurrent subjects straddles a GPA-year boundary, GEMSAS has to decide which of them lands in the more recent — and at most schools more heavily weighted — year. Verbatim:

“Should there be a choice between two or more subjects of equivalent credit points which were studied concurrently, the subjects will be distributed with higher subject results going to the more recent GPA year.”

Higher results go to the more recent year. At a 3:2:1 school that is worth real points, and it is omitted from every third-party explanation we have seen. The calculator above implements it: within each study period, subjects are ordered by result before they are allocated.

Two features of this table matter more than the rest. The top band is flat.A mark of 80 and a mark of 100 both convert to 7. Anything above 80 is invisible to your GPA, which changes where extra effort is worth spending. Automated readings of the published grid routinely mis-align this row and report an 84–80 band at 6.75 — that value belongs to a letter column, not to percentages.

And there is a cliff at 50. A mark of 50 scores 4.0. A mark of 49 scores zero, not 3.9 — unless your institution designated it a conceded pass, which scores 3.5. One mark is worth four grade points at that boundary.

Where no percentage mark exists, GEMSAS maps your institution to one of seven letter columns instead. The calculator supports those columns, but they are transcribed from a visually complex grid and we treat them as an approximation. GEMSAS converts non-Australian transcripts case by case, "taking the minimum and maximum marks into consideration", and publishes no deterministic mapping for any foreign scale. No calculator can faithfully produce a GEMSAS GPA from an overseas transcript — this one included.

Read that table as five formulas, not ten. Here they are in full, including the Deakin variant that only applies in one specific circumstance.

Melbourneis the one most often mis-stated. Its own entry reads: “GPA years will be weighted: the final-minus-2 x 1, the final-minus-1 x 2 and the final x 2.” Final year ×2, divisor 5.

UQis the genuine outlier. It has no GPA years at all: “UQ’s GPA assessments are weighted by credit value of the subjects rather than the year in which the subjects were completed.” Every subject studied while enrolled in the key degree counts — whether or not it counted toward the award — and a combined degree contributes both halves. If your later years are stronger than your earlier ones, UQ will give you your lowest Australian GPA. If they are weaker, UQ will give you your highest. There is also a band between 5.0 and 5.75 where UQ re-reviews the GPA by hand against its own procedure, and nothing can predict that outcome.

Griffith and UWA weight nothing, so a strong first year counts exactly as much as a strong final year. UWA divides by two where only two GPA years exist, and it is the only school that ignores specified and unspecified credit and exchange results entirely.

Because these three sit outside GEMSAS, preferencing them costs none of your six GEMSAS preferences — they are separate applications with separate deadlines. The calculator does not produce a figure for them, because none of the three publishes the GEMSAS year weightings and we will not model a formula that has not been stated.

Which makes the six preferences worth as much thought as the GPA itself, because they are the part of an Australian application you fully control. GEMSAS interviews you at one school only, and the standardised score from that interview may then be considered by the schools further down your list — how GEMSAS works sets out the preference and interview rules that decide which school gets to interview you in the first place.

Two of these are worth restating. At Wollongong, neither GPA nor GAMSAT is ranked at all. Both are hurdles. Interview ranking is 50% Casper and 50% admissions bonuses, and at offer stage GPA, GAMSAT and Casper are all excluded. A 6.9 GPA and a 5.6 GPA are worth precisely the same at Wollongong once both clear 5.5.

At Macquarie, GAMSAT drops out after the interview. Shortlisting is 50:50 GPA and GAMSAT; the offer is 50% GPA and 50% MMI. Your GPA is weighted twice; your GAMSAT once.

We deliberately do not print a combined score. Most schools standardiseboth figures against the applicant pool before combining them — ANU and UWA say so explicitly — and the pool is unknown until applications close. Any site showing you a single “combined GEMSAS score” is inventing the standardisation step. For the GAMSAT side of the equation, see the GAMSAT score calculator, which shows the weighted and unweighted overalls separately for the same reason.

The published minimums run from 5.0 to 5.5 across the GEMSAS schools, and they are minimums — floors to be eligible, not competitive bars. Clearing 5.0 at a school that interviews on a 50:50 GPA/GAMSAT rank tells you almost nothing about whether you would be shortlisted.

Three things move the real bar far more than the published minimum. Rural sub-quotas mean rural applicants compete within a reserved pool, so the effective shortlisting threshold for that cohort is lower — UQ says so in as many words. Bonuses and adjustments are applied to different things at different schools, so an identical 4% is worth more at one than another. And the schools that publish figures publish different kinds of figure: see cutoffs by university, where every number is labelled with what it actually is.
