My final is worth 35% — what score do I need?
Thirty-five per cent is the crossover weight, heavy enough to rescue a term and heavy enough to spoil one. At 77% aiming for a B at 83, the exam needs a 94.1 — and the same paper could leave you at 50 if it goes badly. Six starting grades are worked out below.
Common plus/minus convention; many schools use straight letters or different cut points.
You need 94.1% on the final.
That is within reach — the final is worth 35% of your grade.
🔢 Show the math
- Work graded so far covers 65% of the course; 35% is still to come.
- Points already banked: 77% × 65% = 50.05 points of the 100 available.
- To finish at 83% you still need 32.95 points from the remaining 35%.
- 32.95 ÷ 35 × 100 = 94.14% on what is left.
What you need, at every current grade
With a final worth 35% of your course grade and a B (83% on a plus-minus scale) as the goal, this is the score you need on the final from each starting point:
| Current grade | You need on the final | Reachable? |
|---|---|---|
| 89% | 71.9% | Yes |
| 84% | 81.1% | Yes |
| 80% | 88.6% | Yes |
| 77% | 94.1% | Yes |
| 71% | 105.3% | Not with this final alone |
| 65% | 116.4% | Not with this final alone |

Frequently asked questions
What makes 35% a crossover?
Below roughly a third, a final mostly confirms the grade you already have; above it, the exam starts genuinely rewriting the course. At this weight each point of course grade costs 2.86 exam points, which is close enough to one-to-one that ordinary improvement produces visible movement.
How wide is the range of outcomes from here?
From 50.05 to 85.05 — thirty-five points, which spans four letter grades. Your coursework has banked just over half the available points, and the exam decides the rest. That is worth sitting with before deciding how much preparation this course deserves relative to your others.
My syllabus lists weights that do not total 100. What do I do?
Add them up before trusting any calculation, including this one. Missing weight usually belongs to a component listed elsewhere, and occasionally a percentage is simply mistyped. Entering a 35% final when the real figure is 30 changes the score you need here by nearly three points, and larger errors move it by a whole letter.
How should I revise for a final this heavy?
Spread it, and start with the earliest material. Cumulative exams at this weight tend to test topics your recent coursework stopped touching, which is precisely where the forgotten marks sit. Working old problems under time pressure surfaces those gaps faster than rereading notes that already feel familiar.
