How it works
Attendance % = classes attended ÷ total classes × 100.
- Below the requirement: to reach the target, you need to attend x more classes in a row, where x = (required% × total − attended) ÷ (1 − required%), rounded up.
- Above the requirement: you can miss y classes and still stay at the target, where y = attended ÷ required% − total, rounded down.
Why 75%?
Many Indian universities and boards require at least 75% attendance to sit for exams, though some allow condonation for medical or other valid reasons. Check your institution's exact rule — some count attendance per subject.
