How to Get a First-Class Degree in a Nigerian University — The Honest Guide

By Campusflash Editorial Team  |  Updated March 2026  |  Reading time: 13 minutes

A first-class degree from a Nigerian university opens doors that other degrees simply cannot — international scholarships, graduate assistant positions, competitive postgraduate applications, and a strong signal of your discipline and capability to every employer who sees your transcript.

But it is also genuinely hard to achieve. Less than 5% of Nigerian university graduates finish with a CGPA of 4.50 and above. This guide is for students who want to be in that 5% — and are willing to do what it actually takes to get there.

This is not a motivational speech. It is a practical, honest breakdown of how the Nigerian university grading system works, what first-class graduates do differently, and the specific strategies that separate those who finish with 4.50+ from those who fall just short.

Understanding the Nigerian University Grading System

Before any strategy makes sense, you need to fully understand what you are working with. Most Nigerian universities use the 5.0 CGPA scale, though some have adopted a 4.0 scale following NUC guidelines. This guide focuses on the more common 5.0 scale.

Grade Points on the 5.0 Scale

Degree Classifications on the 5.0 Scale

Key insight: To graduate with a first class on the 5.0 scale, you need an average grade point of 4.50 and above across every course in your entire degree programme. That means you need to score at least 70% in the majority of your courses — consistently — from 100 level to final year. There is no shortcut around that number.

How to Calculate Your CGPA

Understanding your CGPA calculation is not optional — it is essential. Here is how it works:

1. For each course, multiply the grade point you earned by the credit unit of that course. This gives you the quality point for that course.
2. Add up all the quality points across all your courses for the semester.
3. Divide the total quality points by the total credit units for the semester. This gives your GPA for that semester.
4. Your CGPA is the running average of all your semester GPAs, weighted by credit units.

Example: If you score an A (5.0) in a 3-unit course, your quality point for that course is 15. If you score a B (4.0) in a 2-unit course, your quality point is 8. Total quality points = 23. Total credit units = 5. Your GPA for those two courses = 23 ÷ 5 = 4.6.

Critical point: An A in a 4-unit course contributes twice as much to your CGPA as an A in a 2-unit course. Always prioritise your energy on high-unit courses first. One strong performance in a 4-unit course can do more for your CGPA than perfect scores in three 1-unit courses.

The Most Important Thing: Start Strong in 100 Level

Your 100-level results are the foundation of your entire degree. Here is something most students do not fully appreciate until it is too late: it is significantly easier to maintain a high CGPA than to recover a low one.

If you finish 100 level with a CGPA of 4.7, you have enormous room to absorb a tough semester in 200 or 300 level without falling below 4.50. If you finish 100 level with a 3.2, the mathematics of recovery become brutal — you would need near-perfect scores in every remaining semester just to reach the first-class threshold.

This does not mean that recovery is impossible — it is not, and we will address it below. But the single highest-leverage action any Nigerian university student can take is to treat their 100-level year with the same seriousness as their final year. Do not use 100 level to “settle in.” Use it to build.

12 Strategies That First-Class Graduates in Nigeria Actually Use

1. Set the Goal Explicitly on Day One

This sounds obvious, but most students who do not get a first class never actually decided they wanted one. They wanted “good grades” — which is different. First-class graduates make a specific, conscious decision from their first semester: 4.50 minimum, no exceptions.

Write it down. Put it somewhere you see it every day. Break it into semester targets. A first class is not a wish — it is a plan.

2. Master the Continuous Assessment (CA) Game

In most Nigerian universities, Continuous Assessment accounts for 30% to 40% of your total score in each course. This means the exam — which most students prepare for exclusively — is worth at most 60% to 70% of your grade.

First-class graduates treat CA with the same seriousness as the main exam. Here is why this matters so much: CA is the part of your grade you have the most control over. Assignments, tests, practicals, presentations — these are given in advance, graded before results day, and entirely within your hands.

• Submit every assignment — missing one CA component can cost you 5 to 10 marks you cannot recover in the exam
• Type your assignments where possible — a typed, well-formatted submission signals effort and often earns higher marks than handwritten equivalents
• Aim to score at least 25 out of 30 in every CA. This means you only need 45 out of 70 in the main exam to get an A — a much more manageable target
• Do not ever skip a CA test, even if you feel unprepared — a low score is better than a zero

3. Prioritise High-Unit Courses Ruthlessly

Every hour you spend studying is an investment. The return on that investment is highest when you spend it on courses with more credit units.

Look at your course load every semester and identify the courses carrying the most units. These are the courses where an A moves your CGPA the most. Allocate your study time proportionally — not equally. A 4-unit course deserves more of your attention than a 1-unit course, even if the 1-unit course feels easier.

4. Study From Week One — Not From the Exam Timetable

The single most common reason intelligent Nigerian students fall short of a first class is crash reading — compressing a semester’s worth of material into the two weeks before exams. It produces short-term recall and long-term mediocrity.

First-class graduates study continuously throughout the semester:

• Review your lecture notes on the same day they were taught — within 24 hours, while the content is still fresh
• Spend at least one to two hours per day on coursework outside of lectures, even in the early weeks of semester
• By the time the exam timetable drops, you should be revising — not learning for the first time

5. Master Past Questions — Understand Them, Don’t Just Memorise Them

Nigerian university lecturers are creatures of habit. Most repeat the same core questions, concepts, and problem types year after year — sometimes using the exact same phrasing. Past questions are not a cheat code — they are a map of the lecturer’s academic priorities.

• Collect past questions for every course from at least the past five years
• Identify questions or topics that appear repeatedly — these are the lecturer’s favourite areas and almost certainly will appear again
• Do not memorise answers — understand the reasoning behind them. Lecturers rephrase questions; if you only memorised the wording, you will be caught off guard
• Practice answering past questions under timed conditions to build exam speed

6. Attend Lectures Consistently

Most Nigerian universities award 5% of your CA score for attendance. In a semester with eight courses, perfect attendance alone can give you 40 extra marks across all your courses — marks that could be the difference between a B and an A in two or three of those courses.

Beyond the marks, lecturers frequently drop exam hints, explain concepts that are not in the textbook, and develop a familiarity with students who show up consistently. That familiarity can mean the difference of one or two marks in the subjective parts of your grading — marks that determine whether you score 69 (B) or 70 (A).

7. Build Relationships With Lecturers — Professionally

This is not about sycophancy. It is about visibility and academic engagement. Lecturers are human — when they know your face, your name, and your effort, borderline grades often resolve in your favour.

• Sit where you can be seen and engage with the material — the middle rows are ideal
• Ask genuine questions during and after lectures
• Visit lecturers during office hours for clarification — most appreciate students who take the course seriously enough to seek help
• Never be rude, dismissive, or absent-minded in a lecturer’s presence — impressions stick

8. Form a Serious Study Group

The most effective study groups are small, focused, and made up of students who are all genuinely committed to high performance. A group of two to four serious students is more valuable than a group of ten where half are there for social reasons.

• Teach concepts to each other — the act of explaining something is one of the fastest ways to identify gaps in your own understanding
• Divide past questions among group members, solve individually, then compare and discuss
• Use your group for accountability — knowing that others are studying makes it easier to maintain discipline on difficult days

9. Choose Electives Strategically

Most Nigerian university programmes allow you to choose some elective courses. This is one of the most underused tools in a first-class student’s strategy.

• Research which elective courses are taught by lecturers known for fair, transparent grading
• Choose electives in areas where you already have natural strength — an A in an elective you find easy contributes just as much to your CGPA as an A in a course you find difficult
• Avoid electives that are notorious for low grades, unclear grading, or high failure rates — unless they are genuinely required for your career direction

10. Use Academic Resources Beyond Your Lecture Notes

Lecture notes in Nigerian universities are often incomplete. First-class graduates supplement them aggressively:

• Library: Your school library has textbooks, journals, and past project reports that most students never touch
• Google Scholar: For research-based courses, journal articles give you depth that textbooks cannot
• YouTube: For complex topics — particularly in science and engineering — video explanations from channels like Khan Academy, MIT OpenCourseWare, and others can make difficult concepts click in ways a lecture cannot
• Online course platforms: Coursera, edX, and similar platforms offer free courses in almost every subject — use them for the courses you are struggling with

11. Protect Your Health — It Is Not a Side Issue

Sleep deprivation, poor nutrition, and chronic stress are CGPA killers. A tired brain cannot retain information, reason clearly, or perform well in exams — regardless of how many hours it spent reading.

• Aim for seven to eight hours of sleep every night — especially in the weeks before exams
• Eat regular, balanced meals — your brain consumes 20% of your body’s energy and performs poorly without consistent fuel
• Exercise at least three times a week — even light walking reduces stress hormones and improves memory consolidation
• Avoid all-night reading sessions in the days immediately before an exam — they reduce rather than improve performance

12. Track Your CGPA Every Semester and Adjust

Do not wait until final year to discover where you stand. Calculate your CGPA at the end of every semester, compare it against your 4.50 target, and determine exactly how many A grades you need in the next semester to stay on track.

This active tracking keeps you aware of your position and prevents the shock of realising too late that recovery has become mathematically impossible. It also shows you clearly which courses to prioritise, which semesters carry the most weight, and where you can afford a B without jeopardising your target.

What If My CGPA Is Already Low? Is First Class Still Possible?

It depends on how early you are in your programme and how low your CGPA is — but in many cases, yes.

Your 100-level results account for roughly 20 to 25% of your total credit units across a four-year degree. That means 75 to 80% of your CGPA is still ahead of you when you enter 200 level. If you finished 100 level with a 3.2 CGPA, you would need to maintain close to a 4.8 GPA in every remaining semester — difficult, but not impossible if you begin immediately and execute without breaks.

The honest reality: the lower your starting CGPA and the later you are in your programme, the harder recovery becomes. But the students who recover and graduate with a first class are not special — they are simply the ones who stopped accepting where they were and applied maximum focus without waiting for a convenient moment to start.

Campusflash tip: Use a CGPA calculator to run the exact numbers for your situation. Enter your current CGPA, your total credit units so far, and your remaining credit units — then calculate what GPA you need per semester to reach 4.50. That number will either motivate or reset your expectations. Either outcome is useful.

What a First-Class Degree Can Do for You in Nigeria

• International scholarships: Many fully-funded postgraduate scholarships — Commonwealth, Fulbright, Gates Cambridge, Mastercard Foundation — require or strongly prefer a First Class or Second Class Upper. A first class gives you the strongest possible starting position
• Graduate assistantship: Many Nigerian universities retain first-class graduates as graduate assistants, allowing you to pursue a Master’s degree while earning a salary and gaining academic experience
• Competitive employment: Top employers — Big Four firms, investment banks, oil companies, and multinationals — often filter applicants by degree class at the screening stage. A first class gets you through filters that a 2:2 does not
• Postgraduate admission: Both Nigerian and international universities weigh your degree classification heavily in postgraduate admission decisions
• NYSC posting advantage: First-class graduates often receive preferential NYSC PPA postings — including placements at universities and research institutions

Frequently Asked Questions

What CGPA do I need for a first-class degree in Nigeria?

On the 5.0 scale used by most Nigerian universities, you need a CGPA of 4.50 and above. On the 4.0 scale (adopted by some universities following NUC guidelines), the threshold is 3.50 and above. Check your institution’s academic handbook to confirm which scale applies to your programme.

Is a first-class degree worth the sacrifice?

That depends entirely on your goals. If you are targeting international scholarships, competitive graduate programmes, or employers that filter by degree class, then yes — the effort is directly tied to outcomes you care about. If your goals are better served by developing industry skills, building a business, or gaining work experience, a strong 2:1 with excellent certifications and a portfolio may serve you just as well. Be intentional about why you want it, not just that you want it.

Can I get a first class in a Nigerian university without being naturally brilliant?

Yes — and many first-class graduates will tell you exactly this. First-class results in Nigeria are produced far more by discipline, strategy, and consistency than by raw intelligence. The students who consistently score 70 and above are not always the most naturally gifted in their class. They are the most organised, the most prepared, and the most intentional about how they spend their time.

How many hours should I study per day to get a first class?

Quality matters more than quantity. Four focused hours of active studying — where you are testing yourself, solving problems, and reviewing rather than passively reading — will outperform eight distracted hours every time. Most first-class graduates study consistently throughout the semester rather than intensely in short bursts before exams.

Does a first-class degree guarantee a good job in Nigeria?

It significantly improves your chances at the screening stage — particularly with employers who use degree class as a filter. But it does not guarantee anything beyond getting your foot in the door. What happens in the interview room, your interpersonal skills, your professional certifications, and your practical experience are what convert the opportunity into an offer.

Final Word

A first-class degree is not a measure of how smart you are. It is a measure of how seriously you took your opportunity and how deliberately you pursued excellence when nobody was watching.

The strategies in this guide are not secrets — they are habits. Habits that first-class graduates build from their first semester and protect through their final year. Any student, in any Nigerian university, in any course, can build these habits. The question is not whether you are capable. The question is whether you will start today.
