Study Material
Biology
Biology carries more general-awareness marks than physics and chemistry combined, because questions about vitamins, diseases and the human body are asked by every exam from RRB Group D to UPSC Prelims.
The cell comes first because genetics and physiology both depend on it; the human body follows; and nutrition, disease and health round it off, which is the block most heavily examined and most closely tied to current affairs.

Every item is dated, read on the conducting body’s or ministry’s own site, and written with the question it becomes. Read today’s items, take the quiz, or download the month as a PDF.

Each topic is a complete lesson — concepts, formula tables, worked examples and practice questions with explanations.
Weighting
Where Biology marks actually sit
A syllabus lists topics with equal visual weight, and no paper treats them that way. The table below collects what each Biology lesson records about the exams that examine it, so the reading order on this page can be checked against the exams you are actually sitting.
Counts are ranges observed across cycles rather than promises. The notification for your cycle is what fixes the paper, and a topic can move.
| Topic | Examined most in | Typical volume | Lesson |
|---|---|---|---|
| Cell Biology & Genetics | NEET Biology; SSC CGL / CHSL Tier 1; RRB NTPC / Group D | 12–18 questions | 24 min · 16 questions |
| Human Physiology | NEET Biology; RRB NTPC / Group D; SSC CGL / CHSL Tier 1 | 15–20 questions | 25 min · 16 questions |
| Plants, Nutrition & Health | NEET Biology; RRB NTPC / Group D; SSC CGL / CHSL Tier 1 | 15–20 questions | 24 min · 16 questions |
How to use the table rather than read it
Find the rows naming the exam you are preparing for, and study those first regardless of where they sit in the reading order above — the order on this page is pedagogical, built so each lesson can rest on the one before it, and it is not a priority list. Where a topic you are weak at also carries the highest volume in your paper, that row is the whole of your next fortnight.
Method
How to study biology
Biology is the most factual of the sciences and the most closely tied to its textbook, which makes it both the easiest to prepare systematically and the easiest to under-prepare by reading rather than revising.
What the subject actually asks for
- Detail, not gist — in examinations like NEET, questions trace to specific lines, tables, diagram captions and summary points. Skimming for concepts leaves those unlearned.
- Diagrams as content — labelled figures are a source of questions, not illustrations of the text.
- Repeated revision cycles — a largely factual body of material needs several passes rather than one thorough reading, however careful that reading was.
- Terminology held precisely — distractor options are frequently built from adjacent terms.
Read for detail, then revise on a cycle
The single most useful adjustment for biology is to stop reading it as though understanding were the objective. Understand it once, then revise it repeatedly — because what is examined is the detail, and detail decays without repetition in a way that understanding does not.
Questions
Biology — FAQs
What does biology cover in a general studies paper?
Human physiology, nutrition and deficiency diseases, common diseases and their causative agents, plant biology at an applied level, and genetics at the level of basic inheritance. It overlaps substantially with everyday science and with health-related current affairs, which makes it efficient material for a general studies candidate.
Is biology worth preparing if I have a non-science background?
Yes, and it is usually the most accessible of the three sciences for a non-science candidate, because it rewards organised recall rather than problem-solving. The material is descriptive, the categories are clear, and past papers show a short list of topics that recur — deficiency diseases, disease vectors, organ systems and basic inheritance among them.
How should I revise biology so it stays?
As tables and pairs: a vitamin with its deficiency and its source, a disease with its agent and its vector, a hormone with its gland and its effect. Prose notes on biology are read once and retained poorly. Pair-format notes match how the questions are set and can be revised in minutes.
How much genetics is examined?
Basic inheritance, common genetic disorders, and the vocabulary — genes, chromosomes, alleles, DNA structure — at a level that supports current-affairs questions about biotechnology. The mathematical genetics of an entrance syllabus is not usually part of a general studies paper, and past papers for your own exam will confirm the level quickly.
Read the concept, then test it the same day
Every topic ends with practice questions, and a full mock is the fastest way to find out which ones actually stuck.
