What is attendance condonation?
Universities like AKTU, Mumbai University, and Anna University allow absences due to medical reasons or approved activities such as sports, NCC, or NSS to be counted as attendance. Students must submit valid documents and get principal approval. Usually, only 5 to 15 days can be considered, depending on university rules. Submit your application before the deadline the college announces before exams. Missing the window means condonation is not possible for that semester.
Minimum Classes to Attend
How many of the remaining classes must you attend to hit the required %? Enter your current situation below. This is useful when you are mid-semester and want to know the minimum classes you need to go to so you can plan your remaining days.

How many classes can you miss?
There is no single answer. It depends on how many classes have already happened and how many you have attended so far. Someone who joined late and missed the first two weeks is in a completely different spot compared to someone who has been regular until now and wants a break.
That is why this calculator exists. Enter your numbers and you get your exact bunk count. No formula to remember, no guessing.
To use it: enter the classes you have attended, the total classes held so far, and pick your college's required percentage. The calculator tells you how many you can still skip or how many you must attend. It works for 75%, 80%, and 85% requirements.
How to calculate attendance percentage
The formula is simple. Divide classes attended by total classes held, then multiply by 100. If you attended 45 out of 60 classes, your attendance is 75%. To find your bunk limit, the math is: take the required percentage, multiply it by total classes, divide by 100, then subtract what you have already attended. That gives you the number of classes you still need. Any classes beyond that are safe to skip.
Most students get confused because the number keeps changing as new classes are added. That is why a calculator is more useful than doing it in your head.
What is the 75% attendance rule?
Most colleges in India follow UGC guidelines which say a student must attend at least 75% of all classes held in a semester to be allowed to sit for exams. This is not just a warning or a fine. If you fall short, your name goes on the detained list and you do not get a hall ticket. Your marks do not matter at that point.
The rule is per subject in most colleges, not just overall. You could have 80% attendance when you add everything up, but if one subject is at 68%, you can be detained for that subject specifically. This catches a lot of students off guard. Use the Subject-wise tracker to check each subject separately.
VTU and most engineering colleges affiliated with it require 85%, not 75%. Anna University follows 75% but has a condonation window between 65% and 74%. AKTU requires 75% and allows up to 15 days of condonation with valid documents.
Subject-wise vs overall attendance
Your college tracks both. The overall number is what shows on your portal or notice board. The subject-wise number is what the exam section actually checks before issuing hall tickets.
Labs and practicals are often counted separately and the way sessions are recorded varies by department. A 3-hour lab might count as one class or as three separate entries. Check with your department before deciding which sessions are safe to skip.
Attendance rules by university
Different universities have different rules. Here is what most students need to know:
AKTU requires 75% per subject. Condonation of up to 15 days is allowed if you submit valid medical certificates or duty leave documents approved by your HOD.
VTU requires 85% per subject. There is no condonation option at the university level. If you fall short, you repeat the course.
Anna University requires 75%. Students between 65% and 74% can apply for condonation with a medical certificate. Below 65% you are not eligible to sit for exams.
Mumbai University requires 75%. Condonation of up to 10 days is available for medical reasons with proper documentation.
Delhi University requires 66% for most programmes. Some departments set it higher, so check with your college specifically.
JNTU requires 75% with a condonation provision for NCC, NSS, and sports duty with prior approval from the principal.
Pune University (SPPU) requires 75%. Medical condonation is handled at the college level and the limit varies.
If your university is not listed here, select the matching percentage in the calculator and the math works the same way.
How attendance condonation works
Condonation means the college officially marks certain absent days as present. It only happens under specific conditions and requires paperwork. Medical absences need a certificate from a government hospital or a registered doctor with a proper stamp and signature. Duty leave covers things like representing your college in sports, NCC camp, or NSS activities.
The process is usually: collect your medical certificate or duty leave letter, get it signed by your HOD, submit to the exam section before the deadline the college announces. Most colleges have a fixed condonation window before hall tickets are issued. Missing that window means condonation is no longer possible for that semester.
Use the Condonation tab in this calculator to check if the days you can get condoned are enough to bring you above the required percentage.
Frequently Asked Questions
How many classes can I bunk with 75% attendance? ▾
It depends on where you stand right now. For every 3 classes you attend, you can skip 1. But that ratio only holds if you start from 100% and count forward. If you have already missed some classes, your remaining bunk count is lower. Enter your current numbers in the Quick Check tab and you will get the exact count for your situation.
How many classes can I bunk in a semester of 90 classes? ▾
With a 75% requirement and 90 total classes, you need to attend at least 68 classes. That means you can miss up to 22 classes. But this only applies if you start from zero absences. If you have already missed some, subtract those from 22 to get your remaining bunk limit.
What happens if attendance falls below 75%? ▾
You get added to the detained list and will not receive a hall ticket for that subject's exam. Most colleges send a shortage notice first so you have time to recover or apply for condonation. If condonation is not enough to bring you up, you either miss the exam entirely or apply to appear in the next available exam cycle, which delays your degree.
My attendance is 74.9%. Will I be detained? ▾
Most likely yes. Attendance is calculated to one decimal place and 74.9% does not round up to 75% in most college systems. If you are this close, attend one more class. It is not worth the risk.
Can I appear in exams with 65% attendance? ▾
In most colleges, no. 65% is below the 75% minimum required. Your only option is condonation. Anna University allows condonation for students between 65% and 74%. AKTU allows it too if you have valid documents and the shortfall is within the 15-day limit. For other universities, check with your exam section directly.
What documents do I need for attendance condonation? ▾
For medical condonation you need a certificate from a government hospital or a registered doctor. It must have the doctor's stamp, registration number, and your name with dates of illness. For duty leave you need a letter from the organising body, like a sports federation or NCC unit, and prior approval from your principal or HOD. Photocopies are usually not accepted. Submit originals to the exam section within the deadline.
Does NCC or NSS attendance count toward my college attendance? ▾
It depends on your college's policy. Most colleges allow duty leave for NCC camps, NSS special camps, and college sports events at the inter-university or national level. This absence can be condoned if you get prior approval from the principal before leaving, not after you return. Informal NCC parades or local NSS activities on campus generally do not count as duty leave.
Does online class attendance count the same as physical attendance? ▾
In most colleges today, yes. Online classes conducted on platforms like Google Meet or Zoom are marked in the same attendance register as physical classes. If you join but your name is not marked, follow up with the faculty on the same day. Retroactive corrections are harder to get.
What is the attendance rule in VTU? ▾
VTU requires 85% attendance per subject. There is no condonation option at the university level. Students who fall short have to repeat the course. Use the 85% option in this calculator if you are a VTU student.
Does this calculator work for AKTU, VTU, Mumbai University, and Anna University? ▾
Yes. Just select the correct required percentage using the buttons. AKTU is 75%, VTU is 85%, Mumbai University is 75%, Anna University is 75% for most programs. The Condonation tab also lets you enter your university's maximum condonation days so you get an accurate result.
How is lab attendance counted? ▾
Labs are tracked separately from theory in most colleges. A 3-hour lab session may count as one entry or as three separate hours depending on your department's recording method. The lab attendance percentage is calculated independently and you need to meet the required percentage for labs too, not just theory. Check your department's attendance sheet to confirm how they count it.
My overall attendance is fine but one subject is low. Will I be detained? ▾
Yes, you can be detained for just that one subject. The exam section checks attendance subject by subject before issuing hall tickets. If even one subject is below the required percentage, you will not get the hall ticket for that exam. Use the Subject-wise tracker tab to check each subject individually.
