9 chapters of NDA Biology, written to be taught from directly or read alone. No chapter assumes you have read the others, so start wherever you are weakest. The question counts below are live, straight from the bank.
Chapters
Human Physiology
Human Physiology is the largest chapter in NDA Biology — 55 PYQs across 2017–2026, almost all EASY or MODERATE, and almost all pure named-fact recall.
55 PYQs · 9 subtopicsCell Biology
Cell Biology is one of the most reliably-tested NDA Biology chapters — 46 PYQs across 2017–2026, almost all EASY or MODERATE, and almost all pure named-fact recall.
46 PYQs · 8 subtopicsMicrobiology and Disease
Microbiology and Disease is pure named-fact recall — 21 PYQs across 2017–2025, every one EASY or MODERATE, zero derivation.
21 PYQs · 3 subtopicsBiodiversity and Classification
Biodiversity and Classification is pure recall — 12 PYQs across 2018–2026, every one EASY or MODERATE, and not a single HARD question.
12 PYQs · 3 subtopicsPlant Biology
Plant Biology is a 30-PYQ chapter spanning 2017–2026 — mostly EASY and MODERATE, with one HARD transpiration experiment.
30 PYQs · 5 subtopicsReproduction
Reproduction is a compact but high-concept NDA Biology chapter — 16 PYQs across 2020–2026, weighted toward the 'Apply' style where you have to trace a sequence or reason about chromosome numbers, not just recall a fact.
16 PYQs · 4 subtopicsEcology and Environment
Ecology and Environment is a small but reliable NDA Biology chapter — 11 PYQs across 2018–2024, mostly EASY with a few MODERATE multi-statement items.
11 PYQs · 2 subtopicsGenetics and Evolution
Genetics and Evolution is a small chapter in NDA Biology — only a handful of PYQs across 2017–2026, all EASY or MODERATE, and all pure named-fact recall.
4 PYQs · 2 subtopicsBiochemistry
Biochemistry is a small chapter in NDA Biology — only a handful of EASY PYQs across 2017–2026, all pure recall about the chemistry of life.
