Frequently Asked Questions
What is the formula to calculate how many classes I can bunk?
If your current attendance is above the target percentage (T%), the number of classes you can miss is: Safe Bunks = Floor[(Attended × 100 − Total × T) ÷ T].
How do I calculate how many classes to attend to reach 75%?
If your attendance is below 75%, the formula for required consecutive classes is: Required = Ceil[(0.75 × Total − Attended) ÷ (1 − 0.75)] = Ceil[(3 × Total − 4 × Attended)].
Why is 75% attendance mandatory in Indian colleges?
Regulatory bodies like UGC, AICTE, and Medical/Law Councils mandate a minimum 75% attendance to be eligible to sit for semester and university final examinations, with medical relaxations up to 65% in select cases.
