How is the GPA grading system works?

The GPA grading system works with the following calculation. Take an example.

Semester 1:

Code Subject Credit hours Grade Remarks
BBA1 Financial accounting 3 B Good
BBA2 Business Mathematics 3 B+ Very Good

Suppose ‘B’ has credit points 3 and ‘B+’ 3.5

BBA1 = Credit Points * Credit Hours = 3 * 3 = 9
BBA2 = 3 * 3.5 = 10.5

GPA = SUM OF (Credit Points * Credit Hours)/ Sum of Credit Hours
= (10.5+9) / 6 = 3.25

Semester2:

Let GPA in Semester 2 is 3.5. CGPA is calculated as the average of all GPA

CGPA = Average of all GPA’s = (3.25+3.5) / 2= 3.37
