How to Prepare for JAMB Biology 2027

Use the following strategies to organise your preparation.

1. Study the syllabus section by section

Do not jump randomly between topics. Start with Variety of Organisms, then study Form and Functions, Ecology, Heredity and Variations, and Evolution.

2. Understand concepts instead of memorising everything

For example, when studying the heart, understand the direction of blood flow and the functions of its chambers and valves. When studying photosynthesis, understand the conditions required and the products formed.

3. Practise diagrams

Practise identifying and labelling plant cells, animal cells, the heart, the kidney, reproductive organs, flowers and other relevant structures.

4. Pay attention to practical objectives

The syllabus includes food tests, soil investigations, ecological measurements, germination and observations of living organisms.

Practise interpreting experimental results and explaining what they demonstrate.

5. Answer practice questions

After studying a topic, attempt relevant Biology questions without checking your notes. Review mistakes and return to the areas you do not understand.

6. Create a revision timetable

Divide your available study time across the five syllabus sections. Review difficult topics more frequently and reserve time for practice questions and revision.

7. Verify official examination information

Use the official JAMB website and IBASS portal for the applicable syllabus, registration information and examination announcements.
