Marks Needed In Remaining Exam

60

Out of 100 marks in the remaining exam.

This tool solves a very specific, very common problem: you already know your marks from some exams, you have one more exam left, and you want to know exactly how many marks you need on it to reach a target overall percentage across everything combined.

Enter your marks obtained so far and the total marks those were out of, the maximum marks of the remaining exam, and your target overall percentage โ€” the calculator solves for the exact score needed.

Marks Needed = [Target% ร— (Marks So Far Total + Remaining Exam Total) รท 100] โˆ’ Marks Obtained So Far

If this exceeds the remaining exam's maximum marks, the target is not reachable through that exam alone.

Worked example

Question: Scored 340 out of 400 marks so far. One more exam remains, out of 100 marks. Target overall is 80%.
Step 1 โ€” Combined total marks once the remaining exam is included: 400 + 100 = 500
Step 2 โ€” Target total marks needed: 80% of 500 = 400
Step 3 โ€” Subtract marks already secured: 400 โˆ’ 340 = 60
Answer: This student needs 60 out of 100 in the remaining exam to reach an overall 80%.

If the calculated marks needed is higher than the remaining exam's total marks, the target overall percentage cannot be reached through that exam alone โ€” at that point, the target itself needs to be adjusted, or extra credit/other components need to be considered if available.

If you have more than one exam left, first combine their maximum marks into a single "remaining total" figure โ€” this tool then tells you the combined marks needed across all of them, which you can split up based on which subjects you feel more confident in.

How do I calculate marks needed in my last exam?

Enter your marks and total so far, the maximum marks of the remaining exam, and your target overall percentage โ€” the calculator solves for exactly how many marks you need on the remaining exam.

What if the marks needed is more than the exam's total?

That means your target percentage is not achievable through that exam alone โ€” you would need to either accept a lower overall result or make up the gap elsewhere, like extra credit if your course offers it.

Can I use this for more than one remaining exam?

Yes โ€” combine all remaining exams' maximum marks into one number first, and the calculator gives you the combined total needed across them.
