How it works
Frequently asked questions
What is the minimum attendance required?
Most colleges and universities in India require at least 75% attendance to be eligible for examinations, so this calculator uses 75% as the threshold for the Safe zone.
How do the Safe, At risk and Critical statuses work?
Safe means your attendance is 75% or higher. At risk covers 60–74% — you need to attend several classes in a row to recover. Critical is below 60% — you should attend every class from now on to climb back above 75%.
Is my data uploaded anywhere?
