Calculating your Grade Point Average (GPA) and Cumulative Grade Point Average (CGPA) in Nigerian Polytechnics may seem daunting, but with a clear understanding of the grading system and a step-by-step approach, you can accurately determine your academic performance. In this guide, we’ll break down the process into simple steps to help you calculate your GPA and CGPA effectively.
Understanding GPA and CGPA:
GPA is a measure of your performance in a single semester, while CGPA represents your overall performance throughout your academic journey by considering all semesters.
Grading System in Nigerian Polytechnics:
Before we delve into the calculation, it’s important to know the grading system used in Nigerian Polytechnics. The system assigns grades and corresponding grade points based on your scores:
- 100-80: A (Grade Point – 4.00)
- 79-70: AB (Grade Point – 3.50)
- 69-60: B (Grade Point – 3.00)
- 59-50: BC (Grade Point – 2.50)
- 49-40: C (Grade Point – 2.00)
Calculating GPA for a Semester:
To calculate your GPA for a specific semester, follow these steps:
- List your courses with their respective credit units, grades, and grade points.
- Multiply each course’s credit unit by its grade point to get the quality points.
- Add up the quality points for all courses.
- Add up the total credit units for the semester.
- Divide the total quality points by the total credit units to obtain your GPA for that semester.
Example:
First Semester OND1
- Gsp 101: 2 credits, Grade – C, Grade Point – 2.00, Quality Points – 4.00
- Gsp 105: 2 credits, Grade – C, Grade Point – 2.00, Quality Points – 4.00
- Gsp 111: 2 credits, Grade – A, Grade Point – 4.00, Quality Points – 8.00
- … (Repeat for all courses)
- Total Quality Points: 44.00
- Total Credit Units: 15
- GPA = Total Quality Points / Total Credit Units = 44.00 / 15 ≈ 2.9
Calculating CGPA:
To find your CGPA, average the GPAs of all semesters.
- Add the GPAs of all semesters.
- Divide the sum by the number of semesters.
Example: OND1 CGPA
- First Semester GPA: 2.9
- Second Semester GPA: 2.25
- CGPA = (2.9 + 2.25) / 2 ≈ 2.58
Conclusion:
Calculating your GPA and CGPA in Nigerian Polytechnics is a straightforward process that involves understanding the grading system, calculating GPA for each semester, and finding the average for CGPA. Regularly tracking your academic performance empowers you to gauge your progress and set academic goals effectively. Remember, these calculations are a valuable tool to help you excel in your studies and achieve your educational aspirations.
