The rule underneath all of it
You sit four subjects. Use of English is compulsory for almost every candidate, and you choose three more. Those three are not free choices — they are dictated by the course you are applying for, and the requirement is set by JAMB's brochure and by the institution.
The failure is rarely dramatic. It is a candidate who assumed that "science course" meant "any three science subjects", sat the wrong combination, and found out after the exam, when nothing can be changed.
Check it in the right place, in this order
- The JAMB brochure for the course, which lists the UTME subjects required.
- The institution's own requirements, which can be stricter than the minimum and sometimes specify a subject the brochure leaves open.
- The O'level requirement, which is a separate list and catches people out independently — a course can accept your UTME subjects and still reject you on credits.
Do not take a combination from a WhatsApp group, an old blog post, or a senior who sat the exam three years ago. Requirements change, and the cost of being wrong is a whole year.
The combinations people get wrong
- Medicine and health sciences. Candidates drop one of the three sciences in favour of something they score better in. The required three are usually fixed.
- Engineering. The maths and physics pairing is not negotiable; the third is where the variation sits.
- Law and the arts. Literature is commonly required and commonly skipped by candidates who assume "any arts subjects" will do.
- Management and social sciences. Mathematics or Economics requirements surprise candidates who chose a fully arts combination.
Those are patterns, not promises. Verify yours against the brochure for your own year.
Course by course
The combinations people search for most, each with the cut-off picture and O'level requirements:
| Course | Usual UTME subjects (with Use of English) |
|---|---|
| Medicine and Surgery | Biology, Chemistry, Physics |
| Nursing | Biology, Chemistry, Physics |
| Pharmacy | Biology, Chemistry, Physics |
| Law | Literature in English and two Arts or Social Science subjects |
| Computer Science | Mathematics, Physics and one other science |
| Cyber Security | Mathematics, Physics and one other subject |
| Mass Communication | Literature in English and two Arts or Social Science subjects |
| Accounting | Mathematics, Economics and one other subject |
Choosing between two valid options
Sometimes the requirement leaves you a genuine choice. Then pick on evidence, not affection: sit a timed paper in both candidates and compare the scores. People routinely believe they are better at the subject they enjoy, and the marks disagree.
One caution — check whether the subject you prefer is required later for the same course at O'level or in the institution's post-UTME screening. A choice that is fine for JAMB can still fail you a step later.
If you have already sat the wrong combination
It is not the end. You can apply to courses your combination does fit, consider a related course in the same faculty, or resit. What you should not do is nothing, on the hope that the institution will overlook it. They will not.
Questions people ask
How many subjects do I sit in JAMB?
Four. Use of English is compulsory for almost every candidate and you choose three more, but those three are dictated by the course you are applying for rather than freely chosen.
Where should I check my subject combination?
In this order: the JAMB brochure for the course, then the institution's own requirements which can be stricter than the minimum, then the O'level requirement, which is a separate list and catches people out independently.
Which combinations do candidates most often get wrong?
Medicine and health sciences, where candidates drop one of the three required sciences. Engineering, where the maths and physics pairing is not negotiable. Law and the arts, where Literature is commonly required and commonly skipped. And management and social sciences, where a Mathematics or Economics requirement surprises fully arts combinations.
Can a wrong subject combination be fixed after the exam?
No, and that is why it matters. The typical failure is a candidate who assumed that a science course meant any three science subjects, sat the wrong combination, and found out after the exam when nothing could be changed.
