Evolution, adaptation and natural selection
Explain population change using variation, inheritance and differences in reproductive success.
37 min
- 13
Microorganisms, immunity and community health
Distinguish pathogens from vectors and connect transmission routes with biological prevention principles.
42 min
- 14
Biological observation, diagrams and investigations
Plan fair investigations, handle measurements and present biological observations clearly.

- 15
Habitats, Nigerian biomes, soils and populations
Explain ecological distributions through environmental factors, soil conditions and population processes.
35 min
- 16
Biotechnology, breeding and biosafety
Explain traditional and modern applications of biological systems while weighing evidence and limits.
35 min
Expanded original revision units covering major syllabus domains. Current examination-specific objective mapping, specialist sign-off, full practical work and prescribed regional case studies still require review. This is not an official or certified complete examination course.
