Every semester, a list goes up on a college notice board in Hyderabad, Pune or Kolkata: students with attendance shortage, not eligible for end-semester exams. Most names on it belong to students who thought they had “a few more bunks left”. The 75 percent attendance rule is simple on paper, but its arithmetic works against anyone who falls behind. This guide explains the rule, the usual exceptions and the maths.
What the 75 percent attendance rule says
Most Indian universities and boards require a student to attend at least 75% of the classes held in each course (or overall, depending on the regulation) to be allowed to sit the end-semester examination. Professional programmes and some private universities set 80% or 85%. The exact rule, whether it is counted subject-wise or overall, is in each university's academic regulations.
Is attendance counted subject-wise or overall?
It depends on the university. Many count each subject separately, so 90% overall can still hide a shortage in one subject. Check the regulations or ask the class coordinator.
Condonation: the safety net
Most regulations allow a shortfall to be condoned for genuine reasons such as illness, family emergencies or representing the college, usually down to around 65%, with a medical certificate or supporting documents and often a condonation fee. It is a discretionary relief, not an automatic right, and it usually has to be applied for before the shortage list is final.
- Keep medical certificates and prescriptions from the time of illness.
- Submit them to the department promptly, not at the end of the semester.
- Ask whether the college counts NCC, NSS or sports events as on-duty attendance.

The maths: why recovery is slow
Attendance % = attended ÷ held × 100 Classes needed to reach 75% = ⌈ (0.75 × held − attended) ÷ 0.25 ⌉ Classes you can still miss = ⌊ (attended − 0.75 × held) ÷ 0.75 ⌋
At exactly 75%, every missed class needs three attended classes to make up for it, because each attended class also adds to the total held. At 80% the ratio is four to one.
| Attended / held | Current % | Classes needed in a row |
|---|---|---|
| 60 / 90 | 66.7% | 30 |
| 70 / 100 | 70.0% | 20 |
| 84 / 120 | 70.0% | 24 |
| 100 / 140 | 71.4% | 20 |
A student at 70% after 100 classes must attend the next 20 classes without a miss just to reach 75%. If the semester has only 15 classes left, 75% is no longer possible and condonation is the only route.
Practical habits that keep you safe
- Check the official count every two weeks. Personal counts often miss labs and extra classes.
- Keep a buffer of 5%. Plan to sit at 80%, so one illness doesn't push you below 75%.
- Know the classes left. Ask the timetable in-charge how many sessions remain; the best possible percentage depends on it.
- Talk early. Mentors can often arrange extra sessions or advise on condonation if told in time.

Frequently asked questions
What is the 75 percent attendance rule?
A rule in most Indian universities that students must attend at least 75% of classes held to be eligible for end-semester exams.
Can attendance shortage be condoned?
Often yes, for genuine reasons with documents, usually down to around 65% and at the institution's discretion.
How many classes do I need to attend to reach 75%?
⌈(0.75 × held − attended) ÷ 0.25⌉. With 84 of 120, that is 24 classes in a row.
How many classes can I miss at 75%?
⌊(attended − 0.75 × held) ÷ 0.75⌋. With 100 of 120, that is 13.
Is attendance counted per subject?
In many universities yes; check your academic regulations.
