Within a single module, your mark is usually built from several assessments — essays, problem sets, presentations, a final exam — each carrying its own weight. The split between them is not just admin: it tells you where your marks come from, and therefore where your effort is best spent.
How a module mark is assembled
Suppose a module is assessed as 30% coursework and 70% exam, and you score 68 on the coursework and 55 on the exam. Your module mark is the weighted average of the two:
- (68 × 30 + 55 × 70) ÷ 100 = (2,040 + 3,850) ÷ 100 = 58.9
Despite a strong coursework mark, the heavily weighted exam dragged the module down to a 2:2. The lesson is not “exams matter more” in general — it is that this module’s exam mattered more, because it carried 70% of the weight.
The marginal-mark principle
The value of an extra mark depends on the weight behind it. One percentage point on a 70%-weighted exam moves your module mark by 0.7; one point on a 30%-weighted coursework moves it by 0.3. When you are deciding where to spend a limited hour, the highest-weighted assessment with the most room to improve almost always wins. Polishing an essay from 68 to 72 is often worth less than nudging an exam from 55 to 60.
Coursework and exams reward different things
- Coursework rewards depth, planning and redrafting. The marks are “bankable” — once submitted and graded, they are locked in, which lowers your risk.
- Exams reward breadth, recall under time pressure and exam technique. They concentrate a lot of weight into a few hours, raising both risk and opportunity.
A coursework-heavy module lets you secure marks steadily through the term; an exam-heavy one means the term’s outcome is decided late. Knowing the split early tells you how front-loaded or back-loaded your risk is.
Reading your assessment pattern
- Check the weighting for every assessment at the start of term — it is in the module guide. Do not assume an even split.
- Bank the bankable. Strong, early coursework marks reduce how much you need from the exam and lower stress later.
- Map your deadlines against weights. Two pieces due the same week are not equally urgent if one is worth 10% and the other 40%.
- Recalculate after each result. Once a coursework mark lands, you can work out the exam mark you need — the same back-calculation as your degree target, at module scale.

UniGrade stores the weight of every assessment, shows what you have banked versus what is still outstanding in each module, and lets you model future scores with a what-if slider so you can see which assessment actually moves your grade. It is the same weighted-average maths from our calculation guide, applied automatically inside every module.
