Subject Combination for Computer Science in Polytechnics and Universities in Nigeria 2026/2027:- Computer Science remains one of the most competitive and rapidly evolving courses in Nigerian higher institutions. With the consistent growth of the digital economy, cybersecurity, fintech, artificial intelligence, and data science, thousands of students apply for Computer Science every year. Unfortunately, many lose their admission opportunities because they choose the wrong subject combinations in JAMB or ignore key O’level requirements.
This comprehensive guide provides a full breakdown of the correct subject combinations for Computer Science in both polytechnics and universities in Nigeria. It also explains the admission requirements, differences between the two institutions, mistakes to avoid, and what aspiring students must do from SS1 to secure admission without stress. If your goal is to gain admission into Computer Science in the next academic session, this is the most complete breakdown you will find.
What Is Computer Science as a Course
Computer Science is the study of computer systems, computational theories, programming languages, algorithms, artificial intelligence, software development, database management, computer hardware, networks, and cybersecurity. It is not a course for students who dislike mathematics or logical problem solving. Nigerian universities and polytechnics place strong emphasis on mathematics because most of the curriculum is built around logic, statistics, programming principles, and computational analysis.
Students who plan to study Computer Science must begin early to build competence in mathematics, physics, and computer studies. The competition for this course is high because the field opens doors to top-paying jobs and global opportunities.
General O’Level Requirements for Computer Science
To study Computer Science, candidates must have at least five credit passes in WAEC, NECO, or NABTEB. These credits must be obtained in not more than two sittings in most universities, while some federal universities accept only one sitting for competitive courses.
Compulsory O’Level Subjects Include Mathematics, English Language, Physics, Chemistry
One additional science subject such as Further Mathematics, Computer Studies, Biology, or Technical Drawing Some universities also accept Economics or Geography as the fifth subject. However, a strong science background increases your chances of admission.
Subject Combination for Computer Science in Polytechnics and Universities in Nigeria
The Joint Admissions and Matriculation Board (JAMB) has a standard subject combination for Computer Science in universities. Any student who chooses a wrong subject combination automatically disqualifies himself from being considered for admission.
Correct JAMB Subject Combination: Use of English (Compulsory for all candidates), Mathematics, Physics, One of Chemistry, Biology, or Economics
Why Is Mathematics and Physics Subjects Compulsory For Computer Science
Mathematics and Physics are the foundation of programming logic, algorithm design, and computer architecture. Chemistry is sometimes accepted because it shows a science background, especially for institutions that combine Computer Science with Applied Science. Biology is accepted in some schools, especially where the department focuses on bioinformatics or computational biology. Economics is accepted because some universities merge Computer Science with Management Science at the 100 level.
JAMB Subject Combination for Computer Science in Polytechnics
Polytechnics usually have more flexible subject combinations, but mathematics and a science subject remain compulsory. Below is the approved JAMB subject combination for ND Computer Science.
Correct JAMB Subject Combination for Polytechnics: Use of English, Mathematics, Physics and Any of: Chemistry, Biology, Geography, Economics or Computer Studies
Polytechnics tend to allow more variations in the fourth subject, but students must still choose wisely because a science-heavy combination improves your chances of admission.
Direct Entry Requirements for Computer Science
Students who want to apply through Direct Entry (DE) into 200 level must meet any of these conditions:
- ND/NCE/HND in Computer Science or related fields with Upper Credit
- A’level passes in Mathematics and Physics
- JUPEB results in Science subjects such as Mathematics, Physics, and Chemistry
Direct Entry remains one of the simplest routes into competitive courses in some federal universities.
Differences Between Studying Computer Science in a Polytechnic and a University
Many students ask whether the subject combination differs between universities and polytechnics. The requirements are similar, but the training approach is slightly different.
University Focus
Universities focus on the theoretical and scientific foundations of computing. Students spend more time on algorithm design, computational theory, linear algebra, software engineering, statistics, and artificial intelligence. The degree awarded is typically BSc or BTech Computer Science.
Polytechnic Focus
Polytechnics are more practical-driven. Students spend more time learning hardware maintenance, computer networking, programming labs, web development, and ICT applications. The certificates awarded include:
- National Diploma (ND) Computer Science
- Higher National Diploma (HND) Computer Science
Many students proceed to obtain a university degree through Direct Entry after completing HND.
Common Mistakes Students Make When Choosing Computer Science Subject Combinations
Many students lose their admission because of simple but avoidable errors. Below are the most common mistakes.
- Choosing Biology Instead of Physics: Some students mistakenly assume that Computer Science is not a “pure science” course. Physics is almost always compulsory for Computer Science in universities.
- Ignoring Chemistry: While Chemistry is not always required, some universities prefer it as one of the science subjects. Not having it might limit your choices.
- Selecting Commerce or Government: These subjects are irrelevant for a computing discipline and will disqualify a candidate immediately.
- Poor O’level Grades in Mathematics: A credit in Mathematics is compulsory. Anything lower than C6 is not acceptable.
- Choosing Wrong Combinations for Polytechnic Aspirations: Although polytechnics are flexible, choosing art or commercial subjects will still reduce your chances of admission.
Admission Competitiveness and Cut Off Marks
Computer Science is a competitive course. The higher your JAMB score, the better your chances.
General Cut Off Marks
- Federal universities: 160 to 220
- State universities: 140 to 200
- Private universities: 120 to 180
- Polytechnics: 120 to 150
However, competitive schools like UNILAG, UI, UNIBEN, and FUTA may require 200 and above to stand a good chance.

Frequently Asked Questions (FAQs)
Can I study Computer Science without Physics?
No. Most universities require Physics as a compulsory subject. A few polytechnics may allow alternatives, but it is always safer to include Physics.
Is Chemistry compulsory for Computer Science?
Not always. Chemistry is recommended because some universities prefer it, but it is not compulsory for all institutions.
Can a commercial student study Computer Science in university?
Only if the student has the required O’level science subjects. A commercial background alone will not qualify you.
What JAMB score is good for Computer Science?
Aim for 200 and above for federal universities. For polytechnics, a score above 150 is usually enough.
Is Computer Science better in a university or polytechnic?
It depends on your goals. Universities offer deeper theoretical training, while polytechnics offer strong practical skills. Many students start in a polytechnic and later switch to university via Direct Entry.
