Who sets the minimum
UGC does not fix a minimum attendance for UG and PG degrees: its 2025 regulations leave it to each university, with the approval of its statutory bodies. Your university's ordinance or academic calendar gives its figure and any rules on condoning a shortfall.
The formula
Attendance = classes attended / classes held x 100. To reach target T from below, attend n classes in a row, where n = (T x held - 100 x attended) / (100 - T), rounded up. To stay at or above T, you can miss n = (100 x attended - T x held) / T classes, rounded down.
