JAMB Biology Syllabus 2026/2027
The major areas of Biology preparation can be organised around the following broad themes:
- Variety of organisms
- Form and functions
- Ecology
- Heredity and variation
- Evolution
These broad areas contain several topics and subtopics that candidates should study carefully.
1. Living Organisms
The first major area is the study of living organisms.
Candidates should understand the characteristics that distinguish living things from non-living things.
Important areas include:
- Characteristics of living organisms
- Cell structure
- Functions of cell components
- Levels of organisation
- Plant and animal cells
- Tissues

- Classification of organisms
Living things generally carry out processes such as nutrition, respiration, movement, growth, reproduction, excretion and sensitivity.
Do not simply memorise the list. Understand how these characteristics can be identified in actual organisms.
Cell Structure
The cell is the basic structural and functional unit of life.
Study important cell components such as:
- Cell membrane
- Cytoplasm
- Nucleus
- Mitochondria

You should understand the functions of these structures and be able to distinguish between plant and animal cells.
For example, plant cells generally possess structures such as a cellulose cell wall and chloroplasts that are not found in typical animal cells.
The official Biology syllabus specifically includes cell structure, functions of cell components and levels of organisation.
2. Classification of Organisms
Candidates should understand the classification of living organisms and the characteristics of major groups.

How to Prepare for JAMB Biology 2026/2027
1. Start With the Syllabus
Use the syllabus as your checklist.
Tick each topic after studying it and return to difficult areas during revision.
JAMB’s official IBASS platform provides the e-syllabus system, including Biology.
2. Study Biology With Diagrams
Biology becomes easier when you understand structures visually.
Practise drawing and labelling:
- Heart
- Kidney
- Neuron
- Flower
- Digestive system
- Respiratory system
- Plant cells
- Animal cells
3. Use Past Questions
Practise objective questions after studying each topic.
Don’t just check the correct answer. Understand why the other options are wrong.
4. Make Comparison Tables
For example:
| Topic | What to Compare |
|---|---|
| Plant vs animal cell | Cell structures |
| Xylem vs phloem | Transport functions |
| Aerobic vs anaerobic respiration | Oxygen and products |
| Sexual vs asexual reproduction | Number of parents and variation |
| DNA vs RNA | Structure and functions |
5. Revise Frequently
Biology contains many terms and processes, so regular revision is important.
Common Mistakes JAMB Biology Candidates Should Avoid
Reading Without Understanding
Biology contains many facts, but understanding processes is essential.
Ignoring Diagrams
Some concepts are much easier to understand through diagrams.
Memorising Past Answers
Past questions are useful for practice, but memorising answers alone is unreliable.
Ignoring Ecology
Ecology contains several important concepts and should not be left until the last minute.
Neglecting Genetics
Genetics can involve both theory and simple problem-solving. Practise it regularly.
Depending on Unverified “Expo” Materials
Avoid materials claiming to provide guaranteed examination questions. Focus on the official syllabus, legitimate textbooks and practice materials.

Conclusion
The JAMB Biology Syllabus for 2026/2027 provides candidates with a useful roadmap for preparing for the UTME.
Instead of studying Biology randomly, candidates should organise their preparation around the major areas covered by the syllabus. These include living organisms, classification, cell biology, nutrition, transport, respiration, excretion, support and movement, reproduction, growth, coordination, ecology, heredity, variation and evolution.
The official syllabus is designed to help candidates develop knowledge of the diversity and interdependence of living organisms, understand the continuity of life and apply biological principles to everyday life, health, society and the environment.
For the best preparation, study each topic carefully, practise questions regularly, learn important biological terms and use diagrams whenever necessary.
Do not depend entirely on predicted questions. A candidate who understands the underlying concepts is better prepared to answer questions even when they are presented in unfamiliar ways.
Finally, always verify the current syllabus through JAMB’s official IBASS platform before your final revision. JAMB’s official website currently provides access to the syllabus system, and Biology is listed among the available subjects.
Study the syllabus, understand Biology rather than merely memorising it, practise consistently and revise your weak areas.
