How do I calculate what I need on my final?

Use: needed = (target grade - current grade x (1 - final weight)) / final weight. With an 80% target, 70% current grade and a 40% final, you need (80 - 70x0.6)/0.4 = 95%.

Can I still pass if I fail the final?

It depends on the weight. If your final is worth 30% and you have an 80% average, scoring 0% leaves you with 56% - check your syllabus and run the exact numbers.

What grade do I need on a final worth 20%?

With a final worth 20%, every point you need above your current average requires 5 points on the final - so raising an 78% to 80% needs an 88% exam score.

What Do I Need on the Final?

Enter your current grade, your target and the exam weight – and know exactly what score you need.

Formula: needed = (target - current × (1 - weight)) ÷ weight. If the result is above 100%, the target is mathematically out of reach - aim for the best achievable grade shown.

Strategy: Where to Spend Your Study Hours

If you need under 60%: you are safe – review past papers once and protect your sleep.
If you need 60-85%: normal final-exam preparation: 1-2 weeks of spaced review, focused on the topics with the most marks.
If you need 85-100%: be realistic about the risk; ask the professor what topics carry the most weight and whether any extra credit exists.
If you need over 100%: the target is gone – switch goals. Calculate the best grade you can still get and protect your GPA in your other courses. A planned B beats a failed A.
