ISC Percentage Calculator
Enter Class 12 marks to compare your overall average with an English-inclusive best-four percentage.
How the ISC best-four comparison works
The calculator keeps English and selects the three strongest remaining subject percentages. The overall result averages every subject entered.
Use subject requirements when provided
Some universities calculate eligibility from a required subject combination instead of a simple best four. Follow the course instructions when they name specific subjects.

Common questions
How do I calculate ISC percentage?
A common best-four method keeps English and averages the next three strongest subject percentages. The correct method is the one required by the receiving institution.
Is English included in ISC best four?
English is commonly kept in the best-four calculation. This calculator includes it by default and selects the strongest three remaining subjects.
Should practical marks be entered separately?
Usually no. Enter the final subject mark shown on your result unless the institution asks for separate theory and practical components.
Can a university recalculate my ISC percentage?
Yes. Universities may require particular subjects or use their own eligibility calculation.
