Common questions
Can I still pass if I fail the final?
Often, yes — it depends on your current grade and the final's weight. With an 80 going in and a final worth 20%, even a 40 on the final leaves you at 72. Run your exact numbers in the calculator; 'failing the final means failing the class' is only true when the final is very heavily weighted or your cushion is thin.
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.
