Key facts

  • Most Indian universities require about 75% attendance to sit end-semester exams — check your own regulations.
  • Many count attendance per subject, not overall. Run this once per subject if so.
  • Some allow a lower limit with medical or approved leave (condonation), usually with documents.
  • Classes you can miss = ⌊attended ÷ required − held⌋.
  • Classes needed in a row = ⌈(required × held − attended) ÷ (1 − required)⌉.

Worked example

Held 60, attended 42 → 70%. Target 75%:

(0.75 × 60 − 42) ÷ 0.25 = 12 classes in a row

After 12 more: 54 of 72 = 75.0%.

FAQs

Do labs count separately?

Often yes. Many universities track theory and lab attendance separately — enter each one on its own.

What if "best possible" is below the target?

You can't reach it this term by attending alone. Speak to your department early about condonation rules.

Is 75% a national rule?

It's the common university norm, but the exact figure and exceptions come from your university's regulations.
