What is the difference in percentage calculation between best five and all six subjects in CBSE for class twelve marks?

The key difference is which subjects are included in the calculation:

- Best Five Subjects: Only your top five scoring subjects are counted. Add those marks, divide by the total maximum marks for five subjects, and multiply by 100. This usually results in a higher percentage if one subject score is low.
- All Six Subjects: All six subjects are included. Add all marks, divide by the total maximum marks for six subjects, and multiply by 100. This gives an average across every subject, which can lower your percentage if any score is weak.

Some universities or programs may ask for one method over the other, so it’s useful to know both.
