College Attendance & 75% Rule Calculator

Formula & Calculation Methodology

Classes to attend = ceil((Target × Held - 100 × Attended) / (100 - Target)); Classes to skip = floor((100 × Attended - Target × Held) / Target).

Step-by-Step Worked Example

Classes Held: 60 | Classes Attended: 42 | Target: 75%

1. Current Attendance = (42 ÷ 60) × 100 = 70.0% (Deficit: 5.0%)
2. Formula: X = (75 × 60 - 100 × 42) ÷ (100 - 75)
3. X = (4,500 - 4,200) ÷ 25 = 300 ÷ 25 = 12 Classes
4. Recommendation: Attend next 12 consecutive lectures without missing any.

Understanding the 75% Mandatory Attendance Rule in Indian Universities

Regulatory bodies like UGC, AICTE, and state technical universities (such as AKTU, VTU, Mumbai University, Anna University) mandate a minimum of 75% attendance in theory and practical courses to be eligible for end-semester examinations.

Medical condonation usually permits relaxation down to 65% with approved certified documentation.
