Formula

GPA = Sum of (credit hours assigned to the subject × credit points for the grade the student secured) ÷ Sum of the credit hours of all subjects in the batch

Example

1Subject credit hours
2Grading levels and credit points
CodeSubjectCredit hoursGrade received
BBA1Financial Accounting3B
BBA2Business Mathematics3B+
3Credit points calculation

Assume grade B = 3 credit points and grade B+ = 3.5 credit points.

Financial Accounting

  • Total credit points earned = credit points × credit hours
  • 3 × 3 = 9

Business Mathematics

  • Total credit points earned = credit points × credit hours
  • 3.5 × 3 = 10.5

Final GPA

  • GPA = Sum of (credit points × credit hours) ÷ Sum of credit hours
  • (10.5 + 9) ÷ 6 = 3.25
