How To Calculate GPA And CGPA

Let’s take for instance you are a fresher and just started your 100L in mechanical engineering at a Nigerian University. At the end of the first semester your grades were as follows:

Sample 1st semester 100 level GPA

Course CU TT Grade GP QP
MTH101 3 68 B 4.00 12
ENG111 1 57 C 3.00 3
PHY101 3 77 A 5.00 15
GSS101 2 71 A 5.00 10
CHM101 4 80 A 5.00 20
PHY191 3 69 B 4.00 12
STA101 3 92 A 5.00 15
Total 16 87

Summarily, the student did well in the first semester of study.
→ The Total Course Unit for 100 level first Semester is 3 + 1 + 3 + 2 + 4 + 3 + 3 = 19

→ Total Quality Point for 100 level first Semester( Gotten by multiplying GP by CU): 12 + 3 + 10 + 15 + 20 + 12 + 15 = 87 ₹
→ The GPA of the 100L year 1 is gotten by dividing the total Quality Point by the total course unit. Now, it should be 87/19 which gives: 4.58 — to 2 significant figures. That is your first semester GPA.

We are done with calculations related to the first semester. Remember, you can’t get a CGPA without going through two or more semesters. Let’s move on to the second semester of the same level.

Sample 2nd semester 100 level GPA

Course CU TT Grade GP QP
MTH112 3 73 A 5.00 15
ENG112 1 47 D 2.00 2
PHY102 3 75 A 5.00 15
GSS112 2 70 A 5.00 10
CHM1o2 4 67 B 4.00 16
MTH104 3 50 C 3.00 9
GSS122 2 82 A 5.00 10
Total 18 77

→ Now, the total course unit for 100 level second semester is 3 +1 + 3 + 2 + 4 + 3 + 2 = 18
→ The total quality point for 100 level second semester is 15 + 2 + 15 + 10 + 16 + 9 + 10 = 77.
→ The second semester GPA = 77/18 = 4.38.

Now your total year one CGPA = total 1st semester and 2nd semester 100L quality point divided by the total credit units.

Let’s check,

Total credit unit first semester = 19; that of second semester = 18; TT= 37.

Total quality point of first semester = 87; that of second semester = 77; TT= 164.

Now your 100L CGPA = 164/37 = 4.43

What if you’ve entered into year two, how is it done? Let’s do one more!

Sample 1st semester 200 level GPA

Course CU TT Grade GP QP
ENG212 3 83 A 5.00 15
ENG112 1 37 F 0.00
MEC232 3   72 A 5.00 15
GSS212 2 70 A 5.00 10
ENG241 3 78 A 5.00 15
EEE202 3 80 A 5.00 15
CIV212 3 82 A 5.00 15
Total 18 85

How To Calculate GPA And CGPA

→ The total course unit for 200 level first Semester is 3 +1 + 3 + 2 + 3 + 3 + 3 = 18
→ The total quality point for 200 level first semester is 15 + 0 + 15 + 10 + 15 + 15 + 15 = 85.
→ The 200L first semester GPA = 85/18 = 4.72

Now your CGPA on completion of 100L and 200L first semester = total 100L & 200L 1st semester quality point divided by the total credit units.

Total credit unit first semester = 19; that of second semester = 18; that of 200L 1st semester = 18; TT= 55.

Total quality point of first semester = 87; that of second semester = 77; that of 200L second semester = 85; TT= 249.
