What is a WAM?
WAM stands for Weighted Average Mark. It is the main average used by many Australian universities, including the University of Melbourne, Monash, the University of Sydney and the University of New South Wales. Instead of simply adding up your subject marks and dividing by the number of subjects, a WAM gives bigger subjects more influence. Each mark is multiplied by the credit points of that subject, so a 12-credit-point subject counts twice as heavily as a 6-credit-point subject.
The result is a single number between 0 and 100 that summarises your whole academic performance. Universities use it to decide honours eligibility, prizes, scholarships and entry into competitive postgraduate courses. Because it uses your actual marks rather than broad grade bands, a WAM is a very precise measure: the difference between a mark of 81 and 84 still shows up in your WAM, even though both are Distinctions.
Not every university calls it a WAM. Some use “average mark”, some use a course weighted average, and Queensland universities such as UQ traditionally report a GPA instead. The underlying idea, however — a credit-weighted average of everything you have studied — is the same across Australia.
How WAM differs from GPA
A GPA, or Grade Point Average, works differently. Instead of averaging your exact marks, it first converts every mark into grade points using a scale. In Australia that is normally the 7-point scale: a High Distinction is worth 7 points, a Distinction 6, a Credit 5, a Pass 4, and a Fail 0. Those grade points are then weighted by credit points and averaged, giving a GPA between 0 and 7.
This banding step is the key difference. A mark of 85 and a mark of 99 both become 7 points, so a GPA cannot tell them apart — but a WAM of 99 is clearly higher than a WAM of 85. That makes WAM the finer-grained measure, while GPA is the more portable one: because it uses a standard scale, a GPA lets universities, employers and admissions centres compare students whose marks were awarded under different marking cultures.
In short: WAM answers “what marks did you actually average?”, while GPA answers “which grade bands did you mostly sit in?”. If you need a GPA calculated directly from subject grades rather than marks, try our Australia GPA Calculator, which works on the same 7-point scale.
The standard WAM to GPA conversion table
The table below is the standard conversion used by most Australian universities and by GEMSAS. To use it, find the band your mark falls into and read across to the grade points. The subject calculator above applies this table to every subject you enter, then weights the grade points by credit points.
| Mark / WAM range | Grade | Grade points (GPA) | What it means |
|---|---|---|---|
| 85–100 | High Distinction (HD) | 7 | Outstanding achievement |
| 75–84 | Distinction (D) | 6 | Excellent achievement |
| 65–74 | Credit (C) | 5 | Good achievement |
| 50–64 | Pass (P) | 4 | Satisfactory achievement |
| 0–49 | Fail (F / N) | 0 | Requirements not met |
One caution: a quick conversion that simply looks up your overall WAM in this table is only an estimate. Two students can share the same WAM but end up with different GPAs, because the GPA depends on how their marks are spread across the bands. A student whose marks cluster just inside a band scores a higher GPA than a student with the same average whose marks sit just below band boundaries. That is why the subject-by-subject method is the accurate one.
How to calculate your WAM and GPA
The WAM formula is:
The GPA formula follows the same pattern, except each mark is replaced by its grade points from the table above:
Worked example
Suppose a student completes four subjects in a semester:
| Subject | Mark | Credits | Mark × credits | Grade points | Points × credits |
|---|---|---|---|---|---|
| Biology | 82 | 6 | 492 | 6 (D) | 36 |
| Chemistry | 76 | 6 | 456 | 6 (D) | 36 |
| Psychology | 68 | 3 | 204 | 5 (C) | 15 |
| Statistics | 91 | 3 | 273 | 7 (HD) | 21 |
| Totals | 18 | 1,425 | 108 |
WAM = 1,425 ÷ 18 = 79.17. GPA = 108 ÷ 18 = 6.00. The WAM of 79.17 sits in the Distinction band, which matches the GPA of 6.0 — a strong semester. You can check this example by typing the same four subjects into the calculator above.
GEMSAS GPA: applying for graduate medicine
Why GEMSAS uses GPA, not WAM
GEMSAS — the Graduate Entry Medical School Admissions System — handles applications for most Australian graduate-entry medical schools. Because applicants come from dozens of universities with different marking practices, GEMSAS ignores your university's own WAM and recalculates a standardised GPA on the 7-point scale from your individual subject results. That recalculated figure is the one medical schools actually rank.
GEMSAS converts each subject mark to grade points using the standard table above — HD 7, D 6, C 5, P 4, Fail 0 — then weights each subject by its credit value. Three details of the GEMSAS method catch applicants out. First, results are usually combined across the final three years of your bachelor's degree, with the most recent year often weighted most heavily (commonly the final year counts double or more, depending on the school). Second, failed and repeated subjects generally still count. Third, subjects without a percentage mark, such as ungraded passes, are handled under specific GEMSAS rules and may be excluded or assigned values depending on the school.
Most GEMSAS schools require a minimum GPA of 5.0 or 5.5 simply to be eligible, but eligibility is not the same as being competitive. In recent admission cycles, applicants who received interviews commonly held GPAs around 6.5 to 7.0, combined with a strong GAMSAT score; the exact weighting of GPA versus GAMSAT differs by university, and some schools add an interview or portfolio. Because GEMSAS recalculates your GPA its own way, the subject calculator on this page — which converts marks to grade points first, then weights them — gives you a much closer estimate of your GEMSAS GPA than simply converting your WAM. Even so, only GEMSAS's own calculation, using your official transcript, is definitive, so use this tool for planning and check the current GEMSAS admissions guide for the rules that apply to your application year.
Frequently asked questions
What is a good WAM?
A WAM of 75 or above is generally considered strong in Australia because it sits in the Distinction band. A WAM of 85 or above is excellent and places you in the High Distinction band. For competitive courses such as graduate medicine, many successful applicants have a WAM in the high 70s or 80s, although entry also depends on other tests and interviews.
How do I convert WAM to GPA?
Find which band your WAM falls into: 85 and above equals a GPA of 7, 75 to 84 equals 6, 65 to 74 equals 5, 50 to 64 equals 4, and below 50 equals 0. For a more precise result, convert each subject mark to grade points first, weight each one by its credit points, and then average them, which is the method GEMSAS uses.
What GPA do I need for medicine through GEMSAS?
There is no single fixed GPA that guarantees a place in graduate medicine. Most GEMSAS schools set a minimum GPA of 5.0 or 5.5 on the 7-point scale just to be considered, but competitive applicants usually have a GPA of 6.5 or higher. Your GPA is normally combined with your GAMSAT score, and some schools also use an interview or portfolio.
Is WAM calculated the same at every university?
No. The basic idea is the same everywhere — a credit-point weighted average of your marks — but the details differ. Some universities count all subject attempts, some exclude certain first-year subjects, and some use different names such as GPA, average mark or course weighted average. Grade bands can also differ slightly, so always confirm the rules with your own university.
How are failed subjects counted in WAM and GPA?
A failed subject still counts. Its actual mark, for example 38, is included in your WAM weighted by its credit points, and it earns 0 grade points in your GPA. If you repeat the subject, many universities count both attempts, although some replace the first result. One fail can pull an average down noticeably, which is why the weighted GPA method matters.
Does WAM or GPA matter more for jobs?
For Australian employers, your WAM or overall average mark is usually what appears on your academic transcript, so it is the figure local recruiters recognise most. GPA matters more for further study, scholarships and international applications, where a standard scale is needed to compare students from different universities. In practice, most employers care about the band — Credit, Distinction or High Distinction — more than the exact number.
