Imagine this: You’ve just received your semester results from the University of Lagos (UNILAG), and you’re eager to determine your Cumulative Grade Point Average (CGPA). Understanding how to calculate your CGPA is crucial, as it reflects your academic performance and influences your academic standing.
This guide will walk you through the process of calculating your CGPA at UNILAG, ensuring you have a clear understanding of each step involved.
🎯 Understanding Key Terms
Before diving into the calculations, it’s essential to familiarize yourself with some key terms:
-
Credit Unit (CU): Represents the weight of a course. For example, a 3 CU course has more impact on your CGPA than a 2 CU course.
-
Grade Point (GP): A numerical value assigned to each grade. At UNILAG, the grading system is as follows:
Score (%) Grade Grade Point (GP) 70 – 100 A 5.0 60 – 69 B 4.0 50 – 59 C 3.0 45 – 49 D 2.0 40 – 44 E 1.0 0 – 39 F 0.0 -
Quality Point (QP): Calculated by multiplying the Credit Unit (CU) by the Grade Point (GP) for each course.
-
Grade Point Average (GPA): The average performance in a semester, determined by dividing the Total Quality Points (TQP) by the Total Credit Units (TCU) for that semester.
-
Cumulative Grade Point Average (CGPA): The overall average performance across all semesters, calculated by dividing the sum of all Total Quality Points (TQP) by the sum of all Total Credit Units (TCU).
📌 Step-by-Step Guide to Calculating CGPA at UNILAG
Step 1: Calculate Your GPA for Each Semester
To determine your GPA for a semester:
-
List Your Courses: Write down all the courses you’ve taken in the semester.
-
Note the Credit Units (CU): For each course, note its credit unit.
-
Record Your Grades: Write down the grade you received for each course.
-
Determine the Grade Points (GP): Using the grading system above, assign the corresponding grade point to each grade.
-
Calculate the Quality Points (QP): For each course, multiply the Credit Unit (CU) by the Grade Point (GP).
-
Sum Up: Add all the Quality Points to get the Total Quality Points (TQP) and add all the Credit Units to get the Total Credit Units (TCU).
-
Compute the GPA: Divide the Total Quality Points (TQP) by the Total Credit Units (TCU).
Example:
| Course | Credit Unit (CU) | Grade | Grade Point (GP) | Quality Point (QP) (CU × GP) |
|---|---|---|---|---|
| MTH 101 | 3 | A | 5.0 | 3 × 5 = 15 |
| ENG 102 | 2 | B | 4.0 | 2 × 4 = 8 |
| PHY 103 | 3 | C | 3.0 | 3 × 3 = 9 |
| BIO 104 | 2 | D | 2.0 | 2 × 2 = 4 |
Calculations:
-
Total Quality Points (TQP): 15 + 8 + 9 + 4 = 36
-
Total Credit Units (TCU): 3 + 2 + 3 + 2 = 10
-
GPA: 36 / 10 = 3.6
Step 2: Calculate Your CGPA Over Multiple Semesters
To determine your CGPA:
-
Calculate the GPA for Each Semester: Follow the steps outlined above for each semester.
-
Sum the Total Quality Points (TQP) and Total Credit Units (TCU) for All Semesters: Add up all the TQPs and TCUs from each semester.
-
Compute the CGPA: Divide the cumulative Total Quality Points (TQP) by the cumulative Total Credit Units (TCU).
Example:
Assuming the following GPAs and TCUs:
| Semester | GPA | Total Credit Units (TCU) |
|---|---|---|
| 1st | 3.6 | 10 |
| 2nd | 3.2 | 12 |
| 3rd | 3.8 | 11 |
| 4th | 3.5 | 12 |
Calculations:
-
Total Quality Points (TQP): (3.6 × 10) + (3.2 × 12) + (3.8 × 11) + (3.5 × 12) = 36 + 38.4 + 41.8 + 42 = 158.2
-
Total Credit Units (TCU): 10 + 12 + 11 + 12 = 45
-
CGPA: 158.2 / 45 = 3.51
