Why exam percentage matters

Most colleges and employers ask for an exam percentage rather than a list of raw marks. A clean percentage is also how you compare results across schools, courses, and grading systems — the marks themselves are meaningless without the maximum.

How to use it

  1. Add a row for each exam paper.
  2. Type the marks you scored in the Marks column.
  3. Type the maximum marks for that paper in the Out of column.
  4. Read the total, percentage, and letter grade in the result tiles.
  5. Use the share button to send the result on WhatsApp or copy it for your CV.

Tips

  • Don’t pre-convert each paper to a percentage — feed the raw marks straight into the calculator and let it do the math once.
  • If your school weights certain papers more heavily (e.g. final = 40%), use the grade calculator instead.
  • Pair with the final exam calculator to plan your final score before the exam.

Frequently asked questions

How do I calculate exam percentage?

Add up the marks you scored across all exam papers, divide by the total maximum, multiply by 100. The calculator automates this for any number of papers.

Can exams have different maximum marks?

Yes — each row in the calculator has its own "Out of" column. A 75-mark midterm and a 100-mark final mix correctly.

Is this the same as the test average calculator?

Almost — both add up scores. Use the exam percentage calculator when each paper has a different maximum (raw marks). Use the test average calculator when all tests are already on a 0–100 scale.
