How the calculator works
Your attendance is classes attended ÷ classes held × 100. If you are below 75%, the tool finds how many classes in a row you must attend: for example, 40 out of 60 is 66.67%, and you need 20 more classes in a row to reach 75%. If you are above 75%, it tells you how many classes you can miss and still stay at 75%.
Add the classes left this semester to see whether the target is still reachable. Run it subject by subject, because most colleges count attendance per subject.
Staying above 75% at Anna University
Check your attendance portal every week, not just before exams. Medical leave usually needs a certificate submitted on time, and condonation, where it exists, has its own limit. Classes missed early in the semester are the hardest to recover, because each new class moves the percentage less.
