Class 10 Science

This is your complete, chapter-wise practice hub for Class 10 Science. Every question is aligned to the latest NCERT syllabus and mapped to the exact chapters your school follows, so you can revise in the same order you are taught. Across 13 chapters we have 868 practice questions covering all three difficulty levels — Easy to build confidence, Medium to consolidate, and Hard to stretch you toward scoring full marks in the board years.

Class 10 Science rewards concept clarity across physics, chemistry and biology basics. Each chapter on XamBaaz gives you three separately timed quizzes (Easy, Medium, Hard) with exam-grade marking — +2 for a correct answer, −1 for a wrong one and 0 for a skip — the same negative-marking discipline used in CBSE Board exams and the JEE & NEET foundation years. Every question comes with a one-line explanation, so you learn the reasoning behind the answer instead of just memorising the option.

You can start anywhere. Popular starting points include Chemical Reactions and Equations, Acids, Bases and Salts, Metals and Non-metals, all the way through to Our Environment. Work chapter by chapter, watch your accuracy climb on each one, and once you have attempted every chapter the Class 10 Science Subject Mastery Test unlocks — a 30-question, 60-minute cross-syllabus mock that mirrors a real the JEE & NEET foundation years paper.

Practice is completely free to try — no credit card, no app to install. Sign in with Google and your progress, streaks and XP save automatically across every device, so you can revise Class 10 Science on your phone between classes and pick up exactly where you left off.

Each chapter opens with free Key Concepts revision notes — a quick overview, the core concepts defined and key formulas — so you can revise Class 10 Science before you practise. Open any chapter below to read its notes and try sample questions.
