## How to calculate CGPA

Before we start, it is important to take note of the following definitions:

• CU – Credit Units (Each course has a specific no. of CU)
• EXS – Exam Score
• GD – Grading letter (Example: A, B, C, D, and E)
• GP – Grading point (Example: 5, 4, 3, 2, and 1)
• QP – Quality Point (By multiplying GP by CU)

Grade Point Average (GPA) = Total Grade Points (TGP) ÷ Total Credit Units (TCU)

Example: A university course has a total of 4 credit units. You have managed to score the mark of 68% which is equal to 3 Grade Points. Quality Points: 3 × 4 = 12

Example: QP of 56 for 18 CU -1st Semester and 67 QP for 20 CU

(Total Quality Point) ÷ (Total Credit Units) = CGPA

(56 + 67) ÷ (18 + 20)

123 ÷ 38 = 3.24

According to this, the new CGPA evaluation and calculations will be based on this newly approved Point Grading Scale for students to be able to classify their degrees. These include first, second upper, second lower, and third class as the lowest degree classification.

These new evaluation rules imply that any student who will not be able to achieve a CGPA of 1.0 and above shall not be awarded a degree by the university of study.
