General Science

NDA General Science Syllabus and Study Guide

Cover GAT General Science at the correct UPSC depth, from living systems and the human body to food, the solar system and eminent scientists.

In short

General Science is the officially named GAT section. Its scope is elementary: living and non-living, cells and tissues, growth and reproduction, the human body, epidemics, food and balanced diet, the solar system, and achievements of eminent scientists.

Official scope

What UPSC names

  • difference between living and non-living;
  • cells, protoplasm and tissues;
  • growth and reproduction in plants and animals;
  • elementary knowledge of the human body and important organs;
  • common epidemics, their causes and prevention;
  • food as a source of energy, constituents of food and balanced diet;
  • solar system, meteors, comets and eclipses;
  • achievements of eminent scientists.

Learning approach

Biology foundations

Understand terms and functions rather than memorising NEET-level detail.

Health

Keep disease content elementary and factual. This route is not medical advice.

Food and nutrition

Focus on basic nutrients, functions and balanced-diet concepts at school-science depth.

Space basics

Revise solar-system members and the basic geometry of eclipses. Avoid advanced astrophysics.

Scientists

Use only well-established contributions and avoid viral attribution myths.

Boundary

This page is not NEET Biology

No molecular pathways, detailed taxonomy, advanced genetics or medical diagnostics are required unless UPSC explicitly expands its syllabus.

Checked against official NDA & NA GAT sources

Scope authority is the official UPSC NDA notification. Section proportions, where shown, are official approximate syllabus proportions and never predicted weightage.
