The JAMB Biology exam at a glance
Before you practise a single question, know exactly what you are preparing for. In the 2026/2027 UTME, Biology is a computer-based paper with a fixed shape — and knowing that shape is half the battle.
| Feature | JAMB Biology |
|---|---|
| Number of questions | 40 multiple-choice |
| Marks | 100 (each subject is scored out of 100; four subjects = 400) |
| Time | The whole UTME is 2 hours for all four subjects — about 40 seconds per question |
| Negative marking | None — never leave a question blank |
| Format | 100% computer-based (CBT) |
The single most important fact for “past questions” is this: the syllabus changes very little from year to year, so the same topics and question styles come back again and again. That is why practising by topic beats memorising any one year’s paper.
Practise JAMB Biology free (CBT)
The real reason students search for “past questions” is simple — they want to practise like the real exam. You can do that here right now, free, with no download and no sign-up:
- JAMB Biology CBT practice — original, syllabus-based questions in the exact JAMB style, each with a worked explanation the moment you answer.
- Full Biology subject test — sit a complete set the way the UTME presents it.
- Timed Biology practice — build speed at the real ~40-seconds-per-question pace.
- Full mock exam — combine Biology with your other three subjects.
Every question on Belmadeng is written originally by our team to match the current JAMB syllabus. They are genuine practice questions with explanations — not copied past papers and never “expo” — so you learn the method, not just the answer.
Most-repeated JAMB Biology topics
These are the high-frequency areas the UTME returns to almost every year. Master these and you cover the bulk of the marks. Practise any of them free from the Biology syllabus page or jump straight into Biology CBT practice.
- Biotechnology
- Co Ordination and Control
- Evidence of Evolution Iv Mention the Evidences for Evolution
- Evolution Among the Following
- Excretion I Define the Meaning and State the Significance of
- Factors Affecting the Distribution of
- Growth
- Heredity
- Humans and Environment I Identify Ecological Conditions That
- Internal Structure of a Flowering Plant
- Living Organisms
- Local Nigerian Biomes
These are the topics you can practise on Belmadeng right now and more — see all 23 on the Biology syllabus page. For the cross-subject picture, see Most-Repeated JAMB Topics by Subject.
A worked JAMB-style example
Here is one original, JAMB-style Biology question from our bank, with the kind of worked answer you get after every question in the CBT:
Biotechnology is the use of ___ or their products to make useful products.
A. living organisms B. rocks C. plastics D. metals
Answer: A (living organisms). Biotechnology uses living organisms (or their products) to make useful products or processes.
How to use past questions the right way
Downloading a stack of old papers and reading the answers does almost nothing. Here is the method that actually raises Biology scores:
- Practise by topic first. Take one topic at a time until you can score consistently, then move on — far more effective than random full papers early on.
- Always read the explanation — even when you got it right. Understanding why is what transfers to a new question in the exam.
- Then practise timed. Once a topic is solid, drill it against the clock to build the ~40-second pace.
- Target your weak topics. Your results highlight where you lose marks — spend your time there, not on what you already know.
- Space it out. Short daily sessions beat one long cram. Build a realistic schedule with the free study planner.

Where to get official past questions
The only official source of genuine JAMB past questions is JAMB itself, through its e-facility and approved materials at jamb.gov.ng. Treat any site selling “complete past questions and answers” or “2026 runs” with suspicion — many reproduce copyrighted material or are outright scams. Belmadeng gives you free, original, syllabus-accurate Biology practice you can use on any phone as your everyday preparation, and we point you to the official portal for the real thing.
Avoid “expo” and leaked answers
Every year, candidates are cheated by “expo”, “runs” or leaked answers sold on social media. They do not work, they are frequently fake, and JAMB uses many shuffled variants and result checks that can get your result cancelled. There is no shortcut: consistent, syllabus-based Biology practice is the only method that reliably raises a score — and it is free here.
Recommended textbooks
You do not need many books — one solid, syllabus-aligned Biology text plus steady practice is enough. The official recommended texts for Biology are listed on the Biology syllabus page, and you can see the full cross-subject list in JAMB Recommended Textbooks. Always confirm the current recommendations at jamb.gov.ng.
