Class 10 Science MCQ — Chapter-wise with Answers
Practise CBSE Class 10 Science multiple-choice questions chapter by chapter — Physics, Chemistry and Biology — with an instant answer and a step-by-step solution after every question.
CBSE Class 10 Science combines three subjects into one board paper — Physics, Chemistry and Biology — and the board asks a growing share of objective, multiple-choice and assertion-reason questions. Practising MCQs chapter-wise is the most efficient way to cover the whole syllabus, because it lets you drill one chapter at a time, spot the topics you keep getting wrong, and fix them before the exam instead of discovering them in the exam hall.
On TestSaathi you pick a Science chapter and a difficulty level, then practise questions one by one. Each question is marked the moment you answer it, and a step-by-step solution explains the reasoning — so a numerical in Electricity or a reaction in Acids, Bases and Salts is not just marked right or wrong, it is explained. The no-repeat system means you see fresh questions every session rather than memorising a fixed set, and your accuracy is tracked per chapter and per difficulty so your revision stays targeted.

Why practise Science MCQs chapter-wise?
Fix weak chapters
Focus on one chapter until your accuracy climbs, instead of jumping randomly across the syllabus.
Build difficulty
Start easy, then move to application and HOTS questions — the kind the board increasingly asks in the objective section.
Then go timed
Once a chapter feels solid, roll it into a timed mock test to practise speed and accuracy under exam pressure.

Class 10 Science MCQ — FAQs
Are these Class 10 Science MCQs based on the CBSE / NCERT syllabus?+
Yes. Every Science MCQ on TestSaathi is mapped to a chapter of the current CBSE Class 10 Science syllabus — Physics, Chemistry and Biology — following the NCERT textbooks. Questions are practice material created for the platform, not official board papers.
Which Class 10 Science chapters are covered?+
All CBSE Class 10 Science chapters are covered across the three branches: Physics (Light, Human Eye, Electricity, Magnetic Effects), Chemistry (Chemical Reactions, Acids Bases and Salts, Metals and Non-metals, Carbon and its Compounds), and Biology (Life Processes, Control and Coordination, Reproduction, Heredity and Evolution, Our Environment).
Can I practise Science MCQs chapter-wise?+
Yes. You choose a subject, a chapter and a difficulty level (from easy up to HOTS), then practise only that chapter. This chapter-wise focus is the fastest way to strengthen weak topics before the board exam.
Do the MCQs show the answer and explanation?+
Yes. After each question you get the correct answer immediately, along with a step-by-step solution so you understand why it is right — not just what the answer is.
Is it free to practise Class 10 Science MCQs?+
You can start for free. Every new student gets a 7-day trial with 100 practice questions and a few free AI doubt-solving uses. Unlimited chapter-wise practice, previous-year questions and timed exams are part of the paid Question Bank plan.
Can I take a timed Science mock test, not just untimed practice?+
Yes. Besides untimed practice, you can create a "real exam": pick your Science chapters, difficulty and duration, and attempt it under a live countdown with auto-submit and a chapter-wise performance breakdown at the end.
Do I need to install an app?+
No. TestSaathi runs in your browser on any phone, tablet or computer. There is nothing to download — just create a free account and start practising.
How is this different from a Class 10 Science PDF or book of MCQs?+
A PDF gives you the same fixed questions every time. TestSaathi serves fresh, non-repeating questions, marks them instantly, explains each answer, and tracks which chapters and difficulty levels you are weak in — so your revision is targeted, not random.
