Understanding the JAMB Biology Exam:

The JAMB Biology exam aims to evaluate candidates’ knowledge of biological concepts, principles, and their ability to apply this knowledge to real-world situations. The questions encompass various branches of biology, including botany, zoology, ecology, genetics, and more. To excel in this exam, candidates must be well-versed in both theoretical concepts and practical applications of biological principles.

  1. Cell Biology: Cell biology is a foundational aspect of biology, and questions in this category often cover cell structure, cell organelles, cell division, and the functions of cells. Candidates should understand the differences between prokaryotic and eukaryotic cells, the cell cycle, and the role of cellular components.

    Area of Concentration:

    • Cell structure and function.
    • Prokaryotic vs. eukaryotic cells.
    • Cell organelles and their roles.
    • Mitosis and meiosis.
  2. Genetics: Questions related to genetics explore the principles of heredity, genetic variation, and the molecular basis of inheritance. Candidates should be familiar with topics such as Mendelian genetics, DNA structure, genetic disorders, and modern techniques in genetics.                                                                        see also                                                                                                                             WAEC Syllabus for Biology 2024/2025.                                                       JAMB Syllabus for Use of English 2024/2025 PDF

    Area of Concentration:

    • Mendel’s laws of inheritance.
    • Chromosomal theory of inheritance.
    • DNA structure and replication.
    • Genetic disorders.
  3. Ecology: Ecology questions assess candidates’ understanding of the relationships between organisms and their environments. Topics include ecosystems, food webs, energy flow, nutrient cycles, and ecological conservation.

    Area of Concentration:

    • Ecosystem structure and components.
    • Types of interactions in ecosystems.
    • Energy flow and nutrient cycles.
    • Conservation of biodiversity.
  4. Plant and Animal Physiology: This category covers the physiological processes in plants and animals, including topics such as photosynthesis, respiration, digestion, and excretion. Candidates should understand the mechanisms that sustain life processes in both plant and animal organisms.

    Area of Concentration:

    • Photosynthesis and its stages.
    • Cellular respiration.
    • Digestive processes in animals.
    • Osmoregulation and excretion.
  5. Anatomy and Morphology: Questions in this category focus on the structure and form of living organisms, including plants and animals. Candidates should be able to identify and describe anatomical structures, tissues, and organs.

    Area of Concentration:

    • Plant anatomy (e.g., roots, stems, leaves).
    • Animal morphology (e.g., skeletal system, digestive system).
    • Tissues and their functions.

Tips for Effective Preparation:

  1. Review Past Questions: Obtain past JAMB Biology question papers and thoroughly review them. Identify recurring themes, question formats, and the depth of knowledge required for each topic.
  2. Create a Study Plan: Develop a structured study plan that allocates sufficient time to each biological concept. Ensure a balanced approach, covering both theoretical understanding and practical applications.
  3. Use Textbooks and Online Resources: Utilize biology textbooks and reputable online resources to supplement your understanding of complex concepts. Online platforms may offer interactive diagrams, animations, and additional explanations.
  4. Practice Diagram Drawing: Many biology questions involve the interpretation of diagrams. Practice drawing and labeling diagrams related to cell structures, biological processes, and anatomical features. This enhances your visualization and identification skills.
  5. Engage in Practical Applications: Biology is not just about theoretical knowledge; it involves practical applications. Conduct experiments, observe biological phenomena in nature, and relate theoretical concepts to real-world scenarios.
  6. Seek Clarification: If you encounter challenges with specific topics, seek clarification from your biology teacher, classmates, or online tutorials. A clear understanding of fundamental concepts is crucial for success in biology.


As you embark on your journey to excel in the JAMB Biology examination, remember that success is not just about memorizing facts but understanding the intricate web of life and its underlying principles. By focusing on cell biology, genetics, ecology, plant and animal physiology, anatomy, and morphology, you’ll be well-prepared to tackle past JAMB Biology questions and navigate the diverse landscape of biological sciences. May your journey be enlightening, and may success be your companion in this exciting exploration of life’s mysteries. Best of luck!
