Required Attendance Calculator

Find out exactly how many upcoming classes you must attend—or can safely miss—to reach or preserve your target attendance percentage.

Attendance target & academic recovery planner.

Classes Attended So Far

Total Classes Held So Far

Classes Remaining

Target Attendance (%)

Classes to attend

Set your target to 75% — the most common minimum requirement for exam eligibility.

Worked Example — 60/80 attended, 20 classes remaining, 75% target

Attend 15 of the next 20You can still miss 5 and land exactly at 75%

This plans ahead — it doesn't just report where you stand. If you only want your current percentage with no target in mind, the plain Attendance Calculator is the simpler tool for that.
"Not achievable" means even perfect attendance isn't enough. If the result says your target can't be reached, that's the honest ceiling — attending every single remaining class still won't get you there.
