If you're a student at the University of Lagos (UNILAG) — or you're planning to get in — understanding how the grading system works is one of the most important things you can know. This guide breaks down exactly how UNILAG calculates GPA and CGPA, what grade points mean, and what CGPA you need to graduate with the class you're targeting.
Quick answer: UNILAG uses the standard NUC 5.0 grading scale — the same system used by all accredited Nigerian universities. A = 5.0, B = 4.0, C = 3.0, D = 2.0, E = 1.0, F = 0.0. First Class requires a CGPA of 4.50 or above.
1. UNILAG Grading Scale — Full Breakdown
UNILAG follows the National Universities Commission (NUC) standard 5.0 grading scale. Every course you take is graded using this system:
| Score (%) | Letter Grade | Grade Point | Remark |
|---|---|---|---|
| 70 – 100 | A | 5.0 | Excellent |
| 60 – 69 | B | 4.0 | Very Good |
| 50 – 59 | C | 3.0 | Good |
| 45 – 49 | D | 2.0 | Pass |
| 40 – 44 | E | 1.0 | Marginal Pass |
| 0 – 39 | F | 0.0 | Fail |
Important: At UNILAG, you need at least 40% to pass a course. Scoring 39% means you fail — even if it's just 1 mark below the pass mark. Never leave a course to chance.
2. How GPA is Calculated at UNILAG
UNILAG calculates GPA using the exact same formula as every other NUC-accredited university in Nigeria. Here's how it works:
Step 2: GPA = Sum of all Quality Points ÷ Sum of all Credit Units
Your CGPA (Cumulative GPA) is the same calculation but done across all your semesters combined — not just one semester.
Common mistake: Many UNILAG students average their semester GPAs to get their CGPA. This is WRONG — especially if you had different credit unit loads each semester. Always use the full quality points formula, or use our free calculator below.
3. Degree Classes and CGPA Ranges at UNILAG
At graduation, your final CGPA determines your degree classification. These are the same across all Nigerian universities:
"At UNILAG, the difference between a First Class and a Second Upper can be as little as 0.01 CGPA points. Every single course matters."
4. Real Worked Example — UNILAG Student
Let's follow Tolani, a 200-level Engineering student at UNILAG, through one semester:
📘 Tolani's 200L First Semester Results
| Course Code | Course | Units | Score | Grade | Points | Quality Points |
|---|---|---|---|---|---|---|
| GEG 201 | Engineering Mathematics | 4 | 74% | A | 5.0 | 20.0 |
| MEG 201 | Mechanics of Materials | 3 | 65% | B | 4.0 | 12.0 |
| EEG 203 | Electrical Circuits | 3 | 58% | C | 3.0 | 9.0 |
| CEG 201 | Engineering Drawing | 2 | 71% | A | 5.0 | 10.0 |
| GST 211 | Communication Skills | 2 | 62% | B | 4.0 | 8.0 |
| TOTAL | 14 | — | — | — | 59.0 | |
Semester GPA = 59.0 ÷ 14 = 4.21 / 5.0 — Second Class Upper 🌟

5. Tips to Maximise Your CGPA at UNILAG
Understand how credit units affect your GPA
At UNILAG, not all courses carry the same weight. A 4-unit course affects your GPA twice as much as a 2-unit course. This means getting an A in a high-credit-unit course like Engineering Mathematics matters far more than getting an A in a 1-unit elective.
- Focus more on high-unit courses — identify which courses carry 3+ units and prioritise them during study
- Never fail any course — an F (0.0) on a 3-unit course drops your GPA dramatically and takes semesters to recover
- Use continuous assessment wisely — UNILAG's CA typically contributes 30-40% of your final grade. Consistent CA marks reduce the pressure of exams
- Attend all lectures — UNILAG lecturers often use attendance as an unofficial factor in borderline CA grading
- Get past questions — UNILAG exams are highly repetitive within departments. Past questions for each course are essential study tools
- Track your CGPA every semester — use our calculator after every result to know exactly where you stand and what you need next semester
Frequently Asked Questions
-
UNILAG uses the NUC standard 5.0 grading scale: A (70-100%) = 5.0 points, B (60-69%) = 4.0, C (50-59%) = 3.0, D (45-49%) = 2.0, E (40-44%) = 1.0, F (0-39%) = 0.0. GPA is calculated by dividing total quality points by total credit units.
-
You need a cumulative GPA of 4.50 or above on the 5.0 scale to graduate with First Class Honours at UNILAG. This means maintaining an average of at least A-/B+ across all your courses throughout your degree.
-
UNILAG CGPA = Total Quality Points from ALL semesters ÷ Total Credit Units from ALL semesters. Quality points per course = Credit Units × Grade Point. The formula is the same across all NUC-accredited universities in Nigeria.
-
No. UNILAG follows the exact same NUC standard grading system used by all accredited Nigerian universities. The grade points, degree class ranges and CGPA calculation formula are identical across UNILAG, UI, OAU, ABU and other federal universities.
-
A CGPA of 3.50 and above (Second Class Upper) is considered very good at UNILAG and qualifies you for most postgraduate programmes and competitive jobs. A CGPA above 4.50 earns you First Class Honours — the highest academic distinction.
