The formulas

With A classes attended out of T held, and a target p (0.75 for 75%):

  • Attendance = A ÷ T × 100
  • Classes you can still miss = round down (A ÷ p − T)
  • Classes you must attend in a row = round up ((p × T − A) ÷ (1 − p))

The 75% minimum is common in Indian colleges and universities, but the exact rule, and any condonation for medical reasons, is set by your institution. Check your university's regulations.
