How to Calculate CGPA on a 5.0 Scale in Nigeria
In Nigerian universities, the grading system is typically based on a 5.0 scale, which is different from the 4.0 scale used in some other countries. Calculating your Cumulative Grade Point Average (CGPA) on a 5.0 scale can seem daunting, but it’s quite straightforward once you understand the process.
How to Calculate CGPA on a 5.0 Scale in Nigeria
Here’s a step-by-step guide to help you calculate your CGPA on a 5.0 scale in Nigeria.
Step 1: Understand the Grading System
The first step in calculating your CGPA is to understand the grading system used in Nigerian universities. The system is as follows:
- A: 70-100% – Excellent (5.0 grade points)
- B: 60-69% – Very Good (4.0 grade points)
- C: 50-59% – Good (3.0 grade points)
- D: 45-49% – Fair (2.0 grade points)
- E: 40-44% – Pass (1.0 grade point)
- F: Below 40% – Fail (0.0 grade points)
Step 2: Convert Your Grades to Grade Points
The next step is to convert your grades for each course to grade points. For example, if you received an ‘A’ in a course, you would multiply the credit units for that course by 5.0 (the grade point for an ‘A’). If you received a ‘B’ in a course with 3 credit units, you would multiply 3 by 4.0 (the grade point for a ‘B’).
Step 3: Calculate Your Total Grade Points
Once you have converted all of your grades to grade points, add up all of the total grade points to get your total grade points for all of your courses.
Step 4: Calculate Your Total Credit Units
Next, add up all of the credit units for all of your courses to get your total credit units. This will be used to calculate your CGPA.
Step 5: Calculate Your CGPA
Finally, divide your total grade points by your total credit units to get your CGPA. The formula for calculating your CGPA is: CGPA = Total Grade Points / Total Credit Units. For example, if your total grade points are 120 and your total credit units are 30, your CGPA would be 120 / 30 = 4.0.
another interpretation on How to Calculate CGPA on a 5.0 Scale in Nigeria.
incase the maths above is confusing, you can check this simplified calculation below.
Here’s the magic formula:
CGPA = Total Quality Points ÷ Total Credit Units
- Total Quality Points: Add up the quality points for all your courses.
- Total Credit Units: Add up the credit units for all your courses.
Example:
Let’s say you took three courses:
- Course 1: Grade B (4.0 points), 3 credits; Quality points = 4.0 * 3 = 12
- Course 2: Grade C+ (3.5 points), 4 credits; Quality points = 3.5 * 4 = 14
- Course 3: Grade A- (4.7 points), 2 credits; Quality points = 4.7 * 2 = 9.4
Total Quality Points: 12 + 14 + 9.4 = 35.4 Total Credit Units: 3 + 4 + 2 = 9
Your CGPA: 35.4 / 9 = 3.93
Interpreting Your CGPA:
A CGPA of 5.0 is the highest possible, indicating exceptional academic achievement. Generally, a CGPA above 4.0 is considered excellent, 3.0-4.0 is good, 2.0-3.0 is average, and below 2.0 requires improvement. However, keep in mind that specific interpretations may vary depending on your university and program.
It’s important to note that some universities may use a weighted average to calculate the CGPA, where more credit is given to courses with higher credit units. In this case, the formula would be: CGPA = (Total Grade Points x Credit Units) / Total Credit Units Taken. Be sure to check with your university to confirm their specific method for calculating the CGPA.
Calculating your CGPA on a 5.0 scale in Nigeria may seem complicated at first, but with practice, it will become second nature. By following these steps and understanding the grading system, you can easily calculate your CGPA and track your academic progress throughout your time in university
