The WAEC (West African Examinations Council) uses a 9-point grading scale from A1 (highest) to F9 (lowest). Each grade corresponds to a specific percentage range and point value. Understanding this system is crucial for calculating your overall GPA and understanding your academic standing.
Important: GPA calculation is often used by universities for admission, scholarship eligibility, and course placement. Knowing your exact GPA helps you understand your competitive standing.
📊 WAEC Grade Points Scale
Here's the complete WAEC grading scale with corresponding points and percentages:
Points: 4-5 | Highly competitive for any university program
Good Grades (B3-C4)
Points: 3-3.5 | Suitable for most university programs
Acceptable Grades (C5-C6)
Points: 2-2.5 | May limit program options
Pass Grades (D7-E8)
Points: 0.5-1 | Very limited options
📠Cumulative GPA Formula
Your WAEC GPA is calculated using the following formula:
WAEC Cumulative GPA Formula
CGPA = (Sum of Grade Points × Credit Units) ÷ (Total Number of Credits)
Or Simplified (Equal Credit Hours):
CGPA = Sum of All Grade Points ÷ Number of Subjects
Note: WAEC doesn't use formal "credit units" like universities do. The simplified version (dividing total points by number of subjects) is most commonly used for WAEC GPA calculations.
👣 Step-by-Step Calculation Guide
Step 1: List All Your Subjects & Grades
Write down every subject you took in WAEC and the grade you received.
Step 2: Convert Each Grade to Points
Using the table above, convert each grade to its corresponding point value.
Step 3: Add All Points Together
Sum all the grade points from all subjects.
Step 4: Count Total Subjects
Count the total number of subjects you wrote (including failed subjects).
Step 5: Divide to Get GPA
Divide the sum of points by the total number of subjects.
💡 Pro Tip: Always include failed subjects (F9) in your calculation, as they count as 0 points and lower your overall GPA.
📠Real Examples & Calculations
Example 1: Strong Academic Performance (8 Subjects)
Number of Subjects = 10 (failed subject still counts!)
GPA = 27 ÷ 10 = 2.7
Result: Student C has a GPA of 2.7 (acceptable, but limited by the failed subject). Note: The F9 in Further Mathematics reduced the GPA from what it would have been (3 points) to 2.7.
🌟 Understanding the "Best 5" System
Many Nigerian universities use a "Best 5" system for admission, not GPA. Here's how it works:
Best 5 System: Universities select your 5 best grades in relevant subjects and use those for admission, not your overall GPA.
Example: Best 5 Selection
If Student A above applied to study Medicine at a Nigerian university:
Subject
Grade
Selected for Best 5?
English Language
A1
✅ Yes (Required)
Mathematics
A1
✅ Yes (Required)
Biology
B2
✅ Yes (Required)
Chemistry
B2
✅ Yes (Required)
Physics
B3
✅ Yes (5th subject - best remaining)
Geography
B3
⌠Not used
History
C4
⌠Not used
Civic Education
C4
⌠Not used
The university would focus on the Best 5 grades rather than the overall GPA.
💡 Key Point: Even if your overall GPA is low, you might still qualify if your best 5 grades meet the university's requirements. Many students focus on their best subjects for admission.

â“ Frequently Asked Questions
Does a GPA of 2.0 mean I can't go to university?
No. Many universities only require your best 5 subjects. Even with a lower overall GPA, if your best 5 grades are strong, you can still gain admission. Check your target university's requirements.
How is WAEC GPA different from university GPA?
WAEC GPA is calculated from your secondary school grades. University GPA is calculated from your degree-level coursework using a different scale (usually 4.0 or 5.0 scale).
Can I retake subjects to improve my GPA?
Yes. You can retake WAEC as a private candidate. Most universities will consider your best result in each subject, but verify with your specific university.
What's a good WAEC GPA?
GPA 3.5+ is excellent, 3.0-3.5 is very good, 2.5-3.0 is good, 2.0-2.5 is acceptable, and below 2.0 may limit options. However, check your target university's requirements.
Do universities use WAEC GPA or Best 5 for admission?
Most Nigerian universities use the "Best 5" system, not overall GPA. They select your 5 best grades and check if they meet course requirements. Always verify with your target university.
How long is my WAEC GPA valid?
Your WAEC certificate and GPA are valid forever (no expiration). You can use them for university admission, employment, or other purposes indefinitely.
Will a failed subject (F9) prevent university admission?
Not necessarily. If the subject isn't in your best 5 or isn't required for your course, it won't affect admission. However, check specific course requirements.
How do I know if I meet a university's admission requirements?
Visit the university's official website and check the Jamb brochure for your intended course. Most courses specify: minimum grades required in English, Math, and subject-specific requirements.
💪 Tips to Maximize Your WAEC Score
1. Focus on Your Best 5: Even if you have 10 subjects, universities care most about your best 5. Prioritize subjects relevant to your desired course.
2. Target Passing Grades Minimum: Aim for at least C6 (2 points) in every subject. An E8 or F9 can significantly drag down your GPA.
3. Excel in Compulsory Subjects: English and Mathematics are required by all universities. Getting A1-B2 in these opens more program options.
4. Subject-Specific Excellence: Get high grades in subjects related to your desired course (Science for Medicine/Engineering, Humanities for Law/Education).
5. Consider Retaking if Necessary: If you get an F9 or low grades, consider retaking WAEC as a private candidate to improve.
Ready to Improve Your WAEC Scores?
Practice with thousands of WAEC-style questions and track your progress daily.
Understanding your WAEC GPA is important, but remember that universities focus primarily on your best 5 grades relevant to your course. Don't stress if your overall GPA seems low—what matters most is performing well in subjects required for your desired program.
Whether you're aiming for a 4.0 or 2.5 GPA, the key is consistent preparation and targeted improvement in subjects that matter most for your career goals.
