Candidates without a science background fear this section most, yet it is among the most predictable parts of the preliminary. The questions do not go deep into theory; they stay with everyday application and basic concepts.
Three branches, a bounded scope
| Branch | Where the questions come from |
|---|---|
| Physics | Light, sound, heat, electricity, force |
| Chemistry | Elements, compounds, acids and bases, everyday chemistry |
| Biology | The human body, disease, nutrition, plants |
| Modern science | Space, energy, applied technology |
How to use the board textbooks
The class 9–10 general science and biology texts work remarkably well as the base here, because the language and conceptual depth of the questions sit at roughly that level. Read the book through once, then return only to the chapters that matter.
For candidates from a non-science background the advice is single: hold concepts, not formulas. If you understand why something happens, a reworded question does not defeat you.
The question shapes that keep returning
- Scientific explanations of everyday events — why the sky is blue, why iron rusts.
- Diseases and their causes — which pathogen, which vitamin deficiency.
- Units and measurement — which quantity is measured in what.
- Discoveries and discoverers.
- Applied technology — which device works on which principle.
An order of work when time is short
- Biology first — the human body, disease and nutrition yield the most questions.
- Then everyday chemistry and applied physics.
- Then the lists of units, discoveries and discoverers.
- Finally modern science and recent technology.

Frequently asked questions
Yes, and many do. The depth sits at class 9–10 level, so reading the board texts through and holding the concepts is enough.
Mostly no. The questions lean on concept and application rather than calculation, so understanding why something happens serves you better.
From the human body, disease and nutrition chapters in biology — they yield the most questions and the material is comparatively familiar.
