About Us

Why we built this

Class 10 revision usually means re-reading a 200-page textbook the week before the board exam. Most of that time goes to prose you already understand, while the formulae, laws, reactions and definitions you actually need to recall get buried in the middle of a chapter. CheatSheet exists to separate the two.

Every chapter is condensed into scannable blocks — formulae, theorems, identities, reactions, definitions and key points — so a full chapter can be revised in a few minutes instead of an evening.

What you will find here

• Science: 13 chapter-wise cheat sheets covering chemistry, physics and biology, from Chemical Reactions and Equations to Our Environment.
• Maths: 14 chapter-wise cheat sheets from Real Numbers to Probability, with the formulae and theorems you are expected to remember.
• Search and print: a live chapter filter, section jump links, and a clean print stylesheet so you can save any chapter as a PDF.
• Dark mode: light, dark and system themes for late-night study.

Our approach to content

The material follows the NCERT chapter order used by CBSE schools. We keep the results — the formula, the statement of the theorem, the balanced reaction — and leave the derivations and long explanations to your textbook, where they belong. Content is reviewed against the current syllabus and updated when the syllabus changes.

Free and independent

CheatSheet is free to use and has no login wall, no subscription and no app to install. We are an independent study resource and are not affiliated with, endorsed by, or connected to CBSE or NCERT. Textbooks and official syllabus documents remain the authoritative source.
