Here is the mastery CGPA calculation (Grading System).

MASTERY CGPA CALCULATION (Grading System).

5 = A

4 = B

3 = C

2 = D

1 = E

0 = F
…………………….

70-100 = A

60-69 = B

50-59 = C

45-49 = D

40-44 = E

0-39 = F
…………………….
So:

4.50 – 5.00 = First Class

3.50 – 4.49 = 2nd Class Upper

2.40 – 3.49 = 2nd Class Lower

1.50 – 2.39 = 3rd Class

1.0 – 1.49 = Pass


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)

C.U – Credit Units
TCU – Total Credit Unit

G.P – Grade Point
TGP or TQP – Total Grade Point or Quality Point

Thus;
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… 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

Your CGPA for that session will be,
CGPA = 4.31

………… Breaking it Down:…………

√ Let’s Consider a 1st Semester Result as shown below;

S/n Units. 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 °
    ° °
    GPA = TGP/TCU
    = 65/18
    = 3.61

√√ Let us now consider 2nd Semester Result.
NB: We’d carry out same procedure in 1st semester then apply here.
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

NB: Always approximate your point to 2decimal places.
Thus: Your main
CGPA = 4.18

I wish you an academic excellence.
