How to calculate Anna University GPA

Your GPA is a credit-weighted average of your grade points, so higher-credit subjects count more:

GPA = Σ (Credit × Grade Point) ÷ Σ (Credit)

Worked example

Suppose a semester has these subjects:

Subject	Credits	Grade	Points	Credit × Points
Maths	4	A (8)	8	32
Physics	3	A+ (9)	9	27
Programming	4	B+ (7)	7	28
Total				87 / 11 credits

GPA = 87 ÷ 11 = 7.91. CGPA works the same way, but you average your semester GPAs weighted by each semester's credits.
