๐ How to Improve Your Attendance Percentage (and Meet the 75% Rule)
22 June 2026 ยท 6 min read
Most colleges require a minimum attendance โ often 75% โ to sit for exams. The good news: attendance is just arithmetic, so you can always work out exactly where you stand and what you need to do.
How attendance percentage is calculated
Attendance % = (classes attended รท classes held) ร 100. If you have attended 60 out of 80 classes, that is 60 รท 80 ร 100 = 75%.
How many classes must you attend to recover?
If you are below the target, every future class you attend pulls your percentage up. To find how many classes in a row you need to attend to reach a target T%, use: classes needed = (T ร held โ 100 ร attended) รท (100 โ T), rounded up.
Say you have attended 40 of 60 classes (66.7%) and need 75%. You would need to attend roughly the next 24 classes without missing any to get back on track.
How many classes can you safely skip?

- โธIf you are comfortably above the target, calculate your buffer before booking that trip.
- โธRemember: future classes count too, so missing one now costs more when few classes remain.
