What Is CGPA & GPA?

CGPA: Cumulative Grade Point Average. (This is what you have after both
1st and 2nd semester. In summation and Division, amounting to it)

GPA: Grade Point Average ( This is what you have after every

You should also know the following acronyms in the grading system:

C.U: Credit Units

TCU: Total Credit Unit 

G.P: Grade Point 

TGP or TQP: Total Grade Point or Quality Point.

How To Calculate GPA

Thus, the derivation is as follows:

GPA: This is derived by dividing the Total Grade/Quality point
(TQP/TGP) by the Total Credit unit (TCU) for that semester.

For example:

If in a semester, a student earned 90 quality points for 21 credit units, the
GPA will be;  

           90÷21 =

How To Calculate CGPA

CGPA is derived by adding the Total Quality Points (TQP) for all the
semesters to date and dividing by the Total Credit Units to date for all
semester that’s 1st & 2nd.

For example:

If in a semester a student earns a QP of 90 for 21 CU in the first semester
and earns a QP of 87 for 20 CU in the second semester, His/Her CGPA will


           = (90+87) ÷ (21+20)

           =  177 ÷ 41
       = 4.31
Therefore, Your CGPA for that session will be, 

CGPA = 4.31

Breaking it Down:

Let’s Consider a 1st Semester Result as shown in the table below;

S/n  Units x  Grade     G.P
1 3 × (A) 5  15
2 2 × (B) 4  8 
3 2 × (A) 5 10
3 × (A) 5 15
3 × (C) 3 9
6 3 × (D) 2 6
7 2 × (E) 1 2
18 65



          = 65/18
    = 3.61

Let us now consider 2nd Semester Result.

NB: We’d carry out same procedure in 1st semester then apply

But let’s assume our  TCU & TGP to be 20  and 93

GPA for second semester 


            = 4.65

You’ll add first semester and semester together to get CGPA. AS As shown


CGPA = TGP+TGP(1st & 2nd semester) / TCU+TCU(1st & 2nd Semester)

   CGPA = 65+94/ 18+20

          = 159 / 38

          = 4.184210

NB: Always your point to 2 decimal places.

Thus: Your main is
CGPA = 4.18

that’s Second Class Lower division.You can make 4.50 and above, only if you
believe in yourself and your capacity. I wish you success in your academic
