GPA and CGPA Guide
This is based on four (4) point scale as used by most Nigerian
Polytechnics and Colleges of Education.
Academic excellence in Nigerian Polytechnics is measured using
the Grade Point Average (GPA) and Cumulative Grade Point
Average (CGPA). So it is important that all students have insight
on how to calculate their GPA & CGPA so as to be able to evaluate
their academic performance from time to time and improve.
GRADING SYSTEM

Note: Other institutions such as Universities that use different
point scale (usually 5 or 7 points), will have different grading
system.
Class of Degree
3.50 – 4.00 Distinction
3.00 – 3.49 Credit
2.50 – 2.99 Merit
2.00 - 2.49 Pass

Customizing the Software
To customize the software to meet your school requirement,
there are two options to choose from;-
Option-1: Do it yourself – Contact the developer to Download
the source code from here: www.umaryusuf.com
Option-2: Do it for you – Contact the developer with your
specific requirements.
Manual GPA & CGPA Calculation
Here is how the software is doing the calculation for you. A
manual approach to calculate “GPA and CGPA” for a Nigerian
higher institution (Polytechnic and/or College of Education).
We will assume the tables below for a student registered courses
at first year in ND1 or HND1 level.
First Year, First Semester
Course
Code
Credit Unit
(CU)
Grade
Letter
Weight
(W)
Grade Point
(GP) = CU x W
APC 100 3 B 3.0 9
PDP 101 5 C 2.0 10
APP 102 1 BC 2.5 2.5
PPA 103 4 AB 3.5 14
AIT 104 3 A 4.0 12
NTA 105 2 D 1.0 2
Total 18 49.5
GP = 49.5
CU = 18
TGP = 49.5
TCU = 18
GPA = GP/CU = 49.5/18 = 2.75
CGPA = TQP/TCU = 49.5/18 = 2.75

APC 106 5 E 0.5 2.5
PDP 107 4 CD 1.5 6
APP 108 5 AB 3.5 17.5
AIT 109 3 F 0.0 0
NTA 110 3 A 4.0 12
Total 20 38
GP = 38
CU = 20
TGP = 49.5 + 38 = 87.5
TCU = 18 + 20 = 38
GPA = GP/CU = 38/20 = 1.90
CGPA = TGP/TCU = 87.5/38 = 2.30
NB: This Procedure is repeated for following years until
graduation. This explains the working principle of the software
you download above.
Similar approach is applicable for Universities although on a
different point scale (usually 5 or 7 points).
