Class 8 Study Notes: How to Make and Revise Them

Good Class 8 study notes turn a full textbook into a few pages you can revise in an evening. They matter more this year because the new NCERT books for Class 8 explain ideas through stories, activities and puzzles, which makes them pleasant to read but slow to revise. Notes pull out the definitions, formulas, dates and diagrams you will actually be tested on.

This page shows what to put in your notes for each subject, how to organise them, when to revise them, and how to use them for both the school annual exam and the NMMS scholarship test.

What to Include, Subject by Subject

How to Organise Your Notes

• One page per chapter: Start each chapter on a fresh page with the chapter number and title from your 2026-27 book, so notes stay in order across Part I and Part II books.

• Write after the class, not during: Listen in class, then write notes the same evening from the book and your class work. This forces you to understand before you write.

• Formula and fact sheets: Keep a separate sheet for all Mathematics formulas and another for all Science definitions. These are your last-day revision pages.

• Error log: A notebook where you copy every question you got wrong in tests, with the correct method. Read it before each exam.

• Diagrams: Draw each important diagram once neatly in your notes, then practise it from memory.

• Colour with purpose: One colour for definitions and one for examples is enough.

Example: A One-Page Note for a Science Chapter

Here is how a one-page note for Curiosity Chapter 8, "Nature of Matter: Elements, Compounds, and Mixtures", might look. Use it as a model for other chapters.

• Key terms: Element: made of only one kind of atom (iron, oxygen). Compound: two or more elements chemically combined in a fixed ratio (water, carbon dioxide). Mixture: substances physically mixed in any ratio (air, salt solution).

• Key difference: A compound has new properties and needs a chemical change to separate; a mixture keeps the properties of its parts and can be separated by physical methods.

• Separation methods: Filtration, evaporation, magnetic separation, each with one example.

• Diagram: Particle drawings of an element, a compound and a mixture.

• Likely questions: Classify given substances; give two differences between a compound and a mixture.

• My mistakes: Space to add errors from tests.

Notes for NMMS

NMMS needs a different kind of note because both papers are objective. Keep a separate thin notebook with:

• Reasoning patterns: Each type of MAT question (series, analogy, coding, figure counting, direction) with one solved example and the shortcut you used.

• Class 7 quick facts: A few pages per subject from your Class 7 books, since the SAT covers both years.

• Social Science one-liners: Dates, places, rulers, terms and constitutional facts, written as short lines you can test yourself on.

• Mathematics shortcuts: Squares and cubes to 30 and 15, percentage-fraction conversions, divisibility rules.

Note-Making Mistakes to Avoid

• Copying the book: If your notes are as long as the chapter, they will not help you revise.

• Leaving out examples: A definition without an example is hard to recall in an exam.

• Mixing old and new books: Notes from an older sibling may cover chapters that are no longer in Class 8.

• Never updating: Add to your notes after every test, so they grow with your mistakes.

A Revision Schedule

For NMMS, read the reasoning notebook for ten minutes before every practice paper in the final two months.

Reliable Sources for Notes

• Your NCERT textbook: Always the base. Download the current books from the NCERT textbook portal if you lose a copy.

• Your teacher's class work: It shows what your school stresses for the exam.

• State SCERT NMMS papers: Useful for deciding which facts belong in your NMMS notes.

• Ready-made notes: Helpful to check your own notes against, as long as they follow the new books.

Ready-Made or Your Own Notes?

Notes you write yourself help you remember more, because the act of choosing what to write is itself revision. Ready-made notes save time and are useful as a check, or for a subject you find hard to summarise. A good mix is to write your own notes for Mathematics and Science, and use ready-made notes as a cross-check for Social Science and languages, where the books are long.

Testkart lists Class 8 notes from teachers for subjects including Science, English, Hindi and Social Science, made for the new NCERT books such as Curiosity, Poorvi and Malhar.

Notes help you remember, and tests show whether you can use what you remember. After every chapter test, add the questions you got wrong to your error log and fix the gap in your notes. You can take Class 8 practice tests on Testkart after finishing a chapter's notes.
