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 semester).
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;
GPA = TGP÷TCU
90÷21 =
4.28
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
be;
CGPA = TQP÷TCU
= (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 |
| 4 | 3 × (A) 5 | 15 |
| 5 | 3 × (C) 3 | 9 |
| 6 | 3 × (D) 2 | 6 |
| 7 | 2 × (E) 1 | 2 |
| TCU | TGP | |
| 18 | 65 |
Therefore,
GPA = TGP/TCU
= 65/18
= 3.61
Let us now consider 2nd Semester Result.
But let's assume our TCU & TGP to be 20 and 93
respectively.
GPA for second semester
GPA = TGP/TCU
93/20
= 4.65

You'll add first semester and semester together to get CGPA. AS As shown
below;
Mathematically;
CGPA = TGP+TGP(1st & 2nd semester) / TCU+TCU(1st & 2nd Semester)
CGPA = 65+94/ 18+20
= 159 / 38
= 4.184210
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 work.
