Overall percentage79.2%

The overall percentage divides all marks obtained by all available marks. Subjects with higher maximum marks contribute more to the total.

Method

Overall percentage = Σ(obtained marks)/Σ(maximum marks) × 100. The maximum total must be positive, and each obtained mark must lie between zero and its matching maximum.

How this calculation works

Combine obtained marks and maximum possible marks across subjects to find an overall percentage. Subjects with larger maximum marks contribute more to the combined total. This is different from averaging subject percentages equally, which would give every subject the same weight regardless of its mark allocation.

Overall percentage = Σ(obtained marks)/Σ(maximum marks) × 100. The maximum total must be positive, and each obtained mark must lie between zero and its matching maximum.

Worked example

This example uses illustrative inputs. Your current result is shown above.

Obtained marks 80, 72, 91, 65 and 88 total 396. With each subject out of 100, the maximum total is 500. Overall percentage = 396/500 × 100 = 79.2%.

Assumptions and limits

  • Pair each obtained mark with the correct subject maximum in the same list position.
  • Marks must be nonnegative and cannot exceed the matching maximum.
  • This uses mark totals only; board-specific best-of rules, subject exclusions and separate credit weights are not selected automatically.

Questions people ask

Can subjects have different maximum marks?

Yes. Enter each actual maximum. A subject out of 200 then contributes twice the possible marks of one out of 100, matching a total-marks calculation.

Does this determine pass or fail?

No. It gives an overall percentage. Passing may require subject-specific minimums, practical marks or other rules not supplied here.
