Quick answer
Attendance % = attended ÷ held × 100. To stay ≥75% after all remaining classes: you must attend enough that (attended + future attended) ÷ (held + remaining) ≥ 0.75. The bunk mode shows the maximum you can miss.

Frequently asked questions
How is attendance percentage calculated?
Attendance % = (classes attended ÷ classes held) × 100.
How many classes can I bunk and stay above 75%?
If you need min% of held classes: you may miss floor(held − min%×held/100) classes so far — or project forward with “classes remaining.” This tool solves both.
