NCERT Class 10 Science Syllabus & Free Practice Test
Class 10 Science is really four small subjects wearing one name — chemistry, biology, physics, and environment — and most students lose marks by revising them all the same way. This page groups the 13 chapters into the four units they actually belong to, so you know which revision habit applies where before you sit for a mock test.

Study map
Chemical changes
Reactions, salts, metals, carbon compounds, periodic pattern.
Life processes
Transport, control, reproduction, heredity, evolution.
Physics foundations
Light, electricity, magnetism, and energy sources.
Best used as
A pre-revision hub before you launch a chapter test or a mixed paper.
Syllabus by study unit
Study the syllabus in groups, not isolated chapters
Chemistry and physics chapters lean on formulas and diagrams, while biology rewards clean process flow. Revise each unit with the method it responds to instead of one generic plan.
Life processes
4 chaptersHuman body systems, plant transport, reproduction, and inheritance concepts.
- Life Processes
- Control and Coordination
- How do Organisms Reproduce?
- Heredity and Evolution
Physics foundations
4 chaptersRay diagrams, lenses, circuits, and electromagnetism.
- Light - Reflection and Refraction
- The Human Eye and the Colourful World
- Electricity
- Magnetic Effects of Electric Current
Environment and sustainability
1 chaptersFood chains, waste handling, biodiversity, and responsible resource use.
- Our Environment
Practice bridge
Revision path that converts syllabus into practice
Step 1
Turn chapter 1 into a 10-question MCQ drill on reaction types and balancing.
Step 2
Ask for short-answer questions from electricity and magnetism with stepwise solutions.
Step 3
Generate a mixed revision test that combines numericals, diagrams, and one-mark definitions.
Common mistakes
Where students actually lose marks in this paper
Board evaluators consistently dock marks for the same handful of slips: skipping the word equation before the chemical formula, drawing ray diagrams without arrowheads or labels, and giving a one-line biology answer where a process sequence was asked for. None of these are knowledge gaps — they are presentation habits, and they are fixable in a single revision pass.
A useful check before a mock test: cover the chapter title and see if you can still name which unit it belongs to from the concept alone. If you can't, that chapter needs another read-through before you attempt questions from it.
