Attendance % = classes attended ÷ classes held × 100
Classes needed in a row = (0.75 × held − attended) ÷ 0.25, rounded up
| Attended / held | Now | Attend in a row |
|---|---|---|
| 30 / 50 | 60% | 30 |
| 35 / 50 | 70% | 10 |
| 40 / 60 | 66.7% | 20 |
| 42 / 60 | 70% | 12 |
| 55 / 80 | 68.8% | 20 |
Every missed class needs 3 attended classes to make up for it at 75%. That is why falling behind early hurts.
Classes you can miss = attended ÷ 0.75 − held, rounded down
| Attended / held | Now | Can miss |
|---|---|---|
| 48 / 60 | 80% | 4 |
| 54 / 60 | 90% | 12 |
| 70 / 80 | 87.5% | 13 |
| 45 / 60 | 75% | 0 |
| Where | Usual minimum |
|---|---|
| CBSE Class 10 and 12 | 75% |
| Most colleges and universities | 75% |
| Some engineering and autonomous colleges | 80-85% |
| Some courses with labs or clinicals | Separate % for labs |
Rules differ by board, university and course. Your college handbook or exam rules decide. Some colleges count attendance per subject, so use the "Every subject" tab.
Divide classes attended by classes held and multiply by 100. 42 of 60 classes is 70%.
Attend (0.75 × held − attended) ÷ 0.25 classes in a row, rounded up. With 42 of 60, you need 12 more classes in a row.
Attended ÷ 0.75 − held, rounded down. With 48 of 60, you can miss 4 classes and stay at 75%.
In most Indian colleges and for CBSE board exams, yes. Some colleges ask for 80-85%. Check your college rules.
Usually it does not count as attended, but many colleges condone a small shortage for medical reasons with a certificate. Ask your college.
It depends on the college. Many count each subject separately, so check each subject in the "Every subject" tab.
