Final Exam Calculator
Enter your grade before the exam, the final's weight and the grade you're aiming for. You'll see the exam score you need, with a table for every letter grade, so you know exactly what to aim for before test day.
Plan your final exam score
Most classes count the final as 10–30% of the course grade. With a high weight, a strong final can lift your grade a lot, and a weak one can pull it down.
Look at the table: it shows the score you need for an A, B, C and D. If an A needs over 100%, aim for a solid B and focus your revision there.
The formula
Score needed = (target − current × (1 − weight)) ÷ weight. With a 78% and a final worth 25%, a B (80%) needs (80 − 78 × 0.75) ÷ 0.25 = 86%.
Make the most of the time left
Start with the topics that carry the most marks and the ones you got wrong on earlier tests. Practise with timed questions, not just rereading, and spread your revision over several days.
Final Exam Calculator FAQs
What score do I need on my final exam?
It depends on your current grade, the final's weight and the grade you want. Enter all three above, and the table shows the score you need for each letter grade.
What happens if I fail my final?
Switch to the 'What will my grade be?' tab and enter a low exam score to see your course grade. With a final worth 20%, a 50% on the exam lowers an 85% course grade to 78%.
How much is a final exam worth?
Usually between 10% and 30% of the course grade, and sometimes more in college. Check your syllabus or ask your teacher.
Can a final exam replace a test grade?
Some teachers replace your lowest test with the final if it's higher. This calculator uses the standard weighted formula, so ask your teacher about any replacement policy.
