Unit-wise Weightage
Digestion, Circulation, Excretion, Respiration, Nervous System, Locomotion
Largest unit — nephron, heart structure, digestive enzymes are all high-frequency LAQ/SAQ. Expect at least 1 LAQ from this unit.
Male & Female Reproductive Systems, Embryonic Development, Reproductive Health
Menstrual cycle regulation, spermatogenesis, embryo development — strong LAQ. Contraception — SAQ/VSAQ.
Mendelian Genetics, Hardy-Weinberg, Linkage, Sex-linked, Mutations, Evolution
Hardy-Weinberg principle, sex-linked inheritance cross diagrams — SAQ. Mendelian laws, Darwin's theory — VSAQ.
Immunity, Pathogens, Cancer, Drugs
Active vs passive immunity, antibody structure — SAQ. Disease names, immune cells — VSAQ.
rDNA Technology, Transgenic Animals, Human Insulin, PCR
Human insulin production, transgenic animals — SAQ. PCR, restriction enzymes — VSAQ.
Ecosystems, Food Chains, Cycles, Biodiversity, Environmental Issues
Carbon cycle, nitrogen cycle, ecological pyramids — SAQ. Trophic levels, types of succession — VSAQ.
High-yield Focus Areas
- 🔴 Human Anatomy & Physiology (~25 periods) — the dominant unit; kidney, heart, digestion all generate LAQs
- 🔴 Human Reproduction (~14 periods) — menstrual cycle and embryonic development are LAQ favourites
- 🟡 Genetics & Evolution (~14 periods) — Hardy-Weinberg and sex-linkage SAQs are standard
- 🟡 Ecology (~9 periods) — carbon/nitrogen cycles and pyramids as SAQs
