How to use the Attendance / Bunk
Set your required attendance (75% by default — change it if your college needs 80% or 85%).
Enter total classes held and classes attended. The result updates live.
If you're safe, it shows how many classes you can still bunk; if you're short, how many you must attend in a row to recover.
Switch to Subject-wise mode to track each subject separately — everything is saved in your browser for next time.
