Total Credit Carried

This means the total number of credit units of courses that you have written so far till date (both the ones the students passed and the ones he/she failed if any). It is the total unit of all attempted exams so far.

Total Credits Earned

This is the total number of credit units of courses that a student passed so far. It doesn’t count the ones he/she failed here. A unit you earn is a unit that you didn’t fail. A unit failed is a unit lost and such a student has to rewrite such a failed course and pass it to be able to earn it.

To graduate from the NOUN University, a student must earn a certain number of credit units in total (depending on the department and also on whether the student entered through direct entry to 200level or through normal 100level). Usually, the minimum requirement is 120 credit units for normal entry students and 90 units for direct entry students.

The formula for Calculation of GPA

Grade Point Average (GPA) is calculated by adding up all credit units earned for the semester and dividing the figure gotten by the number of credit units registered for the semester. This calculation results in a mathematical mean or average.

The GPA is computed on a semester basis. The formula for calculating GPA is as follows

GPA  =    CUE    CUR

CUE = Credit Unit Earned

CUR = Credit Unit Registered

NOUN CGPA Calculations

The cumulative grade point average (CGPA) is the Total Credit Unit Earned (TCUE) divided by the Total Credit Unit Registered (TCUR). The CGPA is calculated at the end of two (2) or more semesters. The formula for calculating CGPA is as follows:


TCUE = Total Credit Unit Earned

TCUR = Total Credit Unit Registered

Class of Degree

NOUN CGPA Ranges under the new Five (5)- Point Grading Scale for Classification of Degrees.

Class of degree is assigned based on the CGPA upon completion of the Programme, and is presented:

First Class (4.5 to 5.0)

How To Calculate NOUN Exam Result Using New Grading Scale

Multiply the points by the unit of each course to get the grade point for a particular course.


If you score A in a 3 unit course, it means 3×5=15.

If you score B in a 2 unit course, it means 2×4=8.

If you score F in a 3 unit course, it means 3×0=0.

If you score A in a zero unit course, it means 0x5=0. And so on.

CIT101 (2units) AMTH103 (3units) BPHY101 (2units) DMTH101 (3units) FGST101 (0units) A
