How to Calculate CGPA in Anna University?
The CGPA is calculated by taking the weighted average of all the grade points, multiplied by the respective subject credits:
Formula:
CGPA = Σ(Credit × Grade Point) / Σ(Credits)
Example:
Total = (27+32+20) / 9 = 8.78 CGPA
Subject A: 3 credits × 9 (A+) = 27
Subject B: 4 credits × 8 (A) = 32
Subject C: 2 credits × 10 (O) = 20
Total = (27+32+20) / 9 = 8.78 CGPA
