- Grade Point Average (GPA)
The academic performance of a student in any semester is measured with the grade point average, the maximum of which is 5.00 and the minimum 0.00. The grade point average (GPA) is the sum of quality points divided by the total credit unit for all the courses registered in the semester; where, Quality Point (QP) is the product of the credit unit for each course and the grade point for that same course.
- Cumulative Grade Point Average (CGPA)
The cumulative grade point average (CGPA) is the measure of student’s overall academic performance at any given point in his programme. A student’s CGPA is calculated as the sum of all quality points divided by the sum of all credit units, for all courses registered/repeated so far in the programme.
The final cumulative grade point average (Final CGPA) calculated at the end of a student’s academic programme shall determine the class of degree he shall be awarded.
