Computer Science, ICT and Information Systems — The IJMB Route
🟢 Lite — Quick Review (1h–1d)
Rapid summary for last-minute revision before your exam.
Computer Science and Information Technology programmes are among the most competitive and sought-after in Nigerian universities. The IJMB route into Computer Science requires a strong Mathematics background — and in most cases, Physics is also preferred.
Essential combination for Computer Science:
- Mathematics, Physics, Chemistry (MPC): The universal combination for Computer Science, Software Engineering, Information Systems
⚡ Exam tip: If you’re targeting Computer Science at UNILAG, UI, or ABU, your Mathematics grade matters most. Many universities treat Computer Science as a mathematics-based programme — the higher your Mathematics grade, the more likely you are to gain admission over a candidate with the same points but a lower Math grade.
🟡 Standard — Regular Study (2d–2mo)
Standard content for students with a few days to months.

Nigerian Tech Ecosystem and Why Computer Science Matters:
Nigeria’s technology sector has grown rapidly since the early 2000s. Lagos is now recognised as Africa’s leading tech hub — home to tech startups, venture capital firms, and offices of global tech companies.

IJMB Points System for Computer Science in Detail:
The IJMB points calculation matters significantly for competitive CS programmes. Each grade translates to:
- A = 8 points (Distinction)
- B = 7 points (Credit)
- C = 6 points (Credit)
- D = 5 points (Pass)
- E = 4 points (Pass)
- F = 0 points (Fail)
For Computer Science, you typically need at least 3 relevant subjects. However, universities may calculate based on your best 3 subjects or all 4 subjects — confirm with each university’s admissions office.
Example scenarios:
- PCM with grades A, B, C = 21 points (A-grade profile)
- PCM with grades B, B, B = 21 points (B-grade profile — same total but different grades)
- PCM with grades B, B, C = 20 points (good profile)
- PCM with grades C, C, C = 18 points (minimum for some universities)
What if you have a Fourth Subject? Many students take 4 IJMB subjects. Some universities take your best 3 subjects for points calculation; others take all 4. If you have Further Mathematics as a fourth subject and score an A, it can significantly strengthen your application — particularly for AI/ML and advanced Computer Science tracks.
Subject Requirements by University (2024 Update):
| University | CS Points | Math Required | Physics Required | Other |
|---|---|---|---|---|
| UNILAG | 10 | A | B | Chemistry B preferred |
| UI | 9 | B | B | - |
| ABU | 9 | B | B | Chemistry accepted |
| UNIBEN | 9 | B | B | - |
| FUTO | 11 | A | A | Chemistry also considered |
| Covenant | 10 | A | B | - |
| LASU | 8 | B | C | - |
| UNIJOS | 8 | B | C | - |
Software Engineering vs Computer Science: Some universities (like FUTO and a few private universities) now offer Software Engineering as a separate programme. Software Engineering is more focused on the practical aspects of building software — development methodologies, testing, project management — while Computer Science is more theoretical (algorithms, computational theory).
The employment outcome is largely the same. Both programmes qualify you for the same roles in Nigeria’s tech industry.
Nigerian Computer Science Accreditation and COREN: The National Universities Commission (NUC) accredits Computer Science programmes in Nigerian universities. COREN (Council for the Regulation of Engineering in Nigeria) does not directly regulate Computer Science as it does for traditional engineering — but the NUC ensures quality through its accreditation process.
When choosing a university, check that the programme has NUC accreditation — unaccredited programmes may not be recognised for employment or further studies.
Post-IJMB: Working as a Software Developer in Nigeria Once you graduate with a CS degree from a Nigerian university, the global job market is open to you:
- Remote work for US/European companies (Nigeria-based remote developer)
- Nigerian startups and tech companies (competitive salaries)
- International companies (Google, Microsoft, Amazon have hiring programmes for African developers)
- Freelancing (Upwork, Fiverr, Toptal)
- Your own startup (Nigeria’s startup ecosystem is growing rapidly)
