How this is calculated
Divide the points earned by the points possible and multiply by 100: 15 ÷ 30 × 100 = 50%. On the common 10-point-band scale that lands in the F range — you'd have needed 27/30 to reach the A band.
Common questions
How do I calculate what I need on my final?
Take your target grade, subtract your current grade multiplied by the portion of the course that's already graded, then divide by the final's weight. Example: you have an 85, the final is worth 20%, and you want a 90 overall — you'd need (90 − 85×0.8) ÷ 0.2 = 110%, which means a 90 isn't reachable and your realistic ceiling is an 88.
Do withdrawals (W) hurt my GPA?
A W doesn't enter GPA math at all — that's usually the point of withdrawing. It does appear on the transcript, and a pattern of many Ws can raise questions in competitive admissions. One or two strategic withdrawals to protect a GPA is common and rarely damaging.
