Work out your subject mark from weighted assessments, and exactly what you need on what is left — including whether a target is still reachable or already secured.
Leave blank to use the dropdown. Useful for a hurdle mark, or a threshold your institution sets differently.
| Component | Weight | Mark | Weighted score |

Subject marks are weighted averages, and treating them as plain averages is the mistake that produces most wrong answers.
Those two assignments average 78.5%, but they have only earned 31.4 marks toward the subject — because they account for 40% of it. Both numbers are true and they answer different questions. The calculator shows both, labelled.
| Figure | Means | Useful for |
|---|---|---|
| Average of marked work | How you have performed on what's been assessed | Judging how you're tracking |
| Earned so far | Marks banked out of the full 100 | Working out what's still needed |
| Best possible | Earned plus everything remaining at 100% | Checking whether a target is still open |
| Worst possible | Earned plus zero on everything remaining | Checking whether a grade is already safe |
With 31.4 earned and 60% of the subject left, reaching a Credit at 60% needs (60 − 31.4) ÷ 60 × 100 = 47.7% across everything remaining.
| Situation | What it means |
|---|---|
| Needed is 0 or less | Already secured — you could score zero on everything left |
| Needed is under 50 | Comfortable, assuming you pass |
| Needed is 50–80 | Achievable with solid work |
| Needed is 80–100 | Possible but demanding |
| Needed is over 100 | Not reachable — the calculator shows the best target still open |
| Grade | Mark |
|---|---|
| HD — High Distinction | 80–100 |
| D — Distinction | 70–79 |
| C — Credit | 60–69 |
| P — Pass | 50–59 |
| F — Fail | 0–49 |
A weighted total is only part of the picture. Several common rules can override it entirely.
| Rule | Effect |
|---|---|
| Hurdle requirement | You must reach a minimum on a specific piece — often 40 or 50% on the final exam — regardless of your total |
| Attendance or participation | Some subjects require a minimum attendance to pass at all |
| Late penalties | Commonly 5–10% of the assessment's value per day, which the raw weighting does not capture |
| Best-of rules | Some subjects count your best few quizzes rather than all of them |
| Scaling or moderation | Faculties sometimes adjust marks across a cohort after marking |
| Supplementary assessment | A near miss may qualify for a supplementary exam, often capped at a bare pass |
Some assessments move your mark far more than others, and it is worth knowing which before allocating time.
| Assessment | Weight | Range it can move your total |
|---|---|---|
| Weekly quiz | 2% | 2 marks |
| Short assignment | 10% | 10 marks |
| Major assignment | 25% | 25 marks |
| Final exam | 40% | 40 marks |
The other pattern worth noticing is that early assessments set your floor. Marks banked early cannot be lost, which is why the "worst possible" figure in the results is often more reassuring than students expect.
How do I calculate my final grade?
Multiply each assessment mark by its weight, add the results and divide by 100. An 80% on a 30%-weighted assignment contributes 24 marks. Add every piece and you have your subject mark out of 100 — provided the weights total 100%.
What mark do I need on my final exam?
Subtract what you have already earned from your target, then divide by the exam's weight and multiply by 100. If you have 31.4 marks banked and want 60% overall with a 40% exam remaining, you need (60 − 31.4) ÷ 40 × 100 = 71.5%. The calculator above does this and tells you if the answer exceeds 100.
What does "not reachable" mean?
That even a perfect score on everything remaining would fall short of your target. The calculator shows the highest grade still available instead, which is more useful than an impossible percentage. It usually means shifting your target rather than your effort.
Why is my average different from my subject mark?
Because they measure different things. Your average is how you have performed on work that has been marked; your subject mark is how many of the full 100 marks you have earned. Two assignments averaging 78.5% at 20% weight each have earned 31.4 marks toward the subject.
What if my weights don't add up to 100%?
Something is missing or wrong. Check your subject outline — assessments are sometimes listed in separate sections, and participation or attendance components are easy to overlook. The calculator warns you rather than silently rescaling, because a rescaled answer would look plausible and be wrong.
What is a hurdle requirement?
A minimum mark you must reach on a specific assessment to pass the subject, regardless of your total. A common example is 40 or 50% on the final exam. You can fail a subject with a passing weighted total if you miss a hurdle, and no weighted calculation will warn you — check your subject outline.
What are the Australian grade bands?
Most commonly High Distinction from 80, Distinction 70 to 79, Credit 60 to 69, Pass 50 to 59 and Fail below 50. Some universities set High Distinction at 85, and a few use different letters or add a Pass Conceded band. Your subject outline is authoritative.
Do universities round marks up?
Usually not at grade boundaries. A 79.6 is typically recorded as a Distinction rather than being rounded to a High Distinction. Some institutions publish a formal rounding rule, so it is worth checking if you are close to a boundary.
How much can my final exam change my grade?
By its full weight. A 40% exam can move your subject mark anywhere within a 40-point range, from your current earned total to that total plus 40. Nothing else in a typical subject has that leverage, which is why the calculator shows best and worst possible outcomes.
How do late penalties affect my mark?
They apply to the assessment's value, then flow through by its weight. A 10% daily penalty on a 30%-weighted assignment costs 3 marks of your subject total per day. Over a few days that is often more than the difference between grades.
Can I pass if I fail one assessment?
Usually yes, as long as your weighted total reaches the pass mark and the failed piece is not a hurdle. A zero on a 10% assignment leaves 90 marks available, which is plenty. A missed hurdle is different — that can fail you regardless of your total.
Is this the same as a GPA calculator?
No. This works out your mark within a single subject from its assessment components. A GPA calculator combines your final results across several subjects, weighted by credit points. Use this one during a semester and that one once results are in.
Grade calculation is straightforward arithmetic that goes wrong in two predictable ways: averaging instead of weighting, and weights that do not total 100. The calculator handles both, and flags the second rather than producing a plausible wrong answer.
The larger caution is that a weighted total is not the whole assessment rule. Hurdles, attendance minimums, late penalties and moderation all sit outside the arithmetic and can override it. Your subject outline is the document that actually decides your grade.
Once results are released, the GPA and WAM calculator combines them across subjects.
