How do I know how many classes I can bunk?

The "Bunk Calculator" logic depends on your target attendance percentage. If your current percentage is higher than your target (e.g., target is 75%), you have a surplus of attended classes. Our calculator determines how many "absent" markings can be added without letting the final ratio drop below 0.75.

For students using ClassTrack, this calculation happens in real-time. We show you the "Safe Bunks" value for every subject on your dashboard.

Why Students Use a Bunk Calculator?

  • Exam Preparation: Needing extra time to study for a difficult subject.
  • Personal Emergencies: Tracking leeway for health or family reasons.
  • Extracurriculars: Managing time for sports, festivals, or club activities.

Is Bunking Legal in College?

Most educational institutions don't use the term "bunking," but they do define a minimum attendance requirement. As long as you stay above the 75% or 80% mark defined by your university, you remain eligible. Using an attendance tracker for students is the most responsible way to manage this delicate balance.
