📘 About the Marks Percentage

Add the marks of every subject, divide by the maximum total and multiply by 100 — that is your percentage. Enter the marks of each subject (blank rows are ignored) and the maximum marks per subject, usually 100.

For CBSE Class 10 and 12, most admissions use the best five subjects: enter only those five to get the "best of five" percentage.

🧮 Formula

Percentage
Percentage = ΣMᵢ ÷ (n × Max) × 100

Where

  • Mᵢ = marks of subject i
  • n = subjects counted
  • Max = maximum marks per subject
A subject left blank or entered as 0 is not counted.
