CBSE Class 10 Chapter-Wise Notes and MCQs — Every Subject

By StudyOS · 2026-07-21

Class 10 is the first board exam most CBSE students sit, and the syllabus is spread across five subjects with no single place that organises it chapter by chapter. Most "notes" you find online are someone else's handwriting photographed, or a paraphrased Wikipedia page with no exam questions attached. Here's what chapter-wise material should actually contain, and what's live for Class 10 right now.

What "chapter-wise" should actually mean

Three things, not just one:

• Matched to the NCERT chapter order — not topics spliced together from multiple chapters, which is how most generic study guides are built.
• Structured, not a wall of text — definitions, key facts, and formulas up front, so you can revise in minutes, not re-read the whole chapter.
• Paired with self-testing — notes without MCQs tell you what you read; MCQs tell you what you actually remember. You need both.

What's in a Class 10 chapter kit on StudyOS

Every chapter — free, no sign-in required for most of it:

• Structured notes (Key Points tab) — key definitions, facts, and formulas for the chapter, downloadable as a PDF
• Mind map — the whole chapter as one visual tree
• Flashcards — for the next-day 2-minute review
• 10 MCQs — enough to self-test right after reading

Premium adds, per chapter:

• 20 MCQs, graded Easy / Medium / Hard / HOTS — the same spread CBSE actually uses in board papers
• Assertion-Reason questions — the format most students never practise until the exam itself; see how the four answer types work
• Case-Based Questions — the passage-plus-questions format that's now 25% of every CBSE paper
• Question Bank — short and long answer questions in the exact format board papers ask them, not just MCQs
• Daily Practice Problems (DPP) — subtopic-wise practice sets, so you can drill one specific concept instead of redoing the whole chapter
• Important board questions — pulled from real past papers, with answer hints

Plus, per subject: full mock papers — board pattern, board timing, so you sit a complete practice exam before the real one.

Class 10 subject breakdown

• Science — 24 chapters across Physics, Chemistry, and Biology
• Social Science — 33 chapters across History, Geography, Political Science, and Economics
• Mathematics — 25 chapters, notes built around formulas and worked concepts, MCQs kept conceptual rather than pure computation
• English — 27 chapters across prose, poetry, and the supplementary reader
• Hindi — both Course A and Course B covered, chapter names kept in romanized English throughout

How to actually use it

Don't read the notes and stop there. Read the notes once, close the tab, do the 10 free MCQs, and see what you got wrong. Go back to only that part of the notes — not the whole chapter. That's the method that makes a 15-minute revision session actually stick; the full version is in how to study any NCERT chapter in 30 minutes.
