Find out about an attendance shortage while you can still fix it.

Enter the hours from your attendance sheet. ClassCalc shows where each subject stands against 75%, how many classes you need to attend to get back if you are short, and how many hours you can still miss for the days you cannot make it.

Safe. You can still miss 5 hours and stay above 75%.

How it works

  1. Open your attendance sheet

    Your department sheet or the KTU portal lists hours attended and hours conducted for every subject.

  2. Enter the two numbers

    Attended, then total. The percentage updates as you type.

  3. Check it every couple of weeks

    A shortage caught in the first month of the sem is a few classes. The same shortage in the last month is a condonation fee or a repeated sem.

FAQ

What is this?

A calculator for KTU attendance. Enter the attended and total hours for a subject and it tells you if you are safe, how many hours you can still miss, or how many classes you need to attend to get back to 75%.

How does it help?

It shows a shortage while there is still time to fix it. Most students find out in the last month of the sem, when the only options left are a condonation fee or repeating the sem.

Where do I get the hours from?

Your department attendance sheet, the KTU portal, or your college ERP. Use hours, not the number of periods. A three hour lab counts as three.

What are 65% and 60% for?

75% is what you need to write the exam. Below that, condonation may be given down to 65%, and in some cases 60%, with a fee and usually a reason. Pick a target above to see the numbers for that band.

Is this official?

No. It is only a calculator. Your college attendance sheet is the one that counts, so check it before you act on anything here.
