Frequently asked questions
How is attendance percentage calculated?
Classes attended ÷ classes held × 100. For example, 45 out of 60 classes is 75%.
How many classes can I miss at 75%?
Divide the classes you attended by 0.75 and subtract the classes held so far, then round down. With 45 of 56 attended, 45 ÷ 0.75 = 60, so you can miss 4 more classes and still have exactly 75%.
How many classes must I attend to reach 75%?
Each class you attend raises your percentage only a little, so the answer can be large. The calculator gives the exact number of classes you'd have to attend in a row, assuming no more absences.
Does it work for lab or practical attendance?
Yes. Enter the lab sessions held and attended separately and use your college's requirement for labs.
Is 75% attendance compulsory?
Many Indian universities and boards require 75% to sit the exams, with some allowing condonation on medical or other grounds. Check your own university's rules.
