GPA & CGPA Measurement in National University
EPS(Earned Point Secured) is measured by the product of Grade Point and Credit of the same course. The total EPS one student will get in the whole year will be divided by total credits offered in one year, and the net CGPA will be calculated from that result. No credit will be gained for those get below ‘D grade’ rather that is deliberated as ‘F grade’. If one can improve from the F grade to a higher, then the credit will be included in the CGPA.
Calculation method for GPA & CGPA
GPA= ΣPS (Total Point Secured in a Year)
ΣCR (Total Credit offered in a Year)
CGPA = ETPS of (1st year + 2nd year + 3rd year + 4th year) + Earned Grade point/points
Total number of credits completed in the whole program
