ICSE Best-of-Five and ISC Best-of-Four Percentage: How College Admission Aggregates Work

Many colleges and universities that use ICSE or ISC marks for admission calculate the percentage as a best-of-five (for ICSE) or best-of-four (for certain ISC-related university admissions) average, rather than taking the average across all subjects.

For ICSE: the best-of-five calculation typically includes English and the best four other subjects. The exact method and which subjects are included can vary by institution — some colleges specify mandatory inclusions.

For ISC: some university programmes calculate admission percentage from the best four subjects (excluding subjects like Physical Education). The exact method depends on the university.

This matters most during May–July when college admission processes are active. Before any calculation, check the exact method specified by the institution or board you are applying to — do not rely on general guides, including this one, for the final computation.
