Be clear on what this is. A formula and revision book, not full chapter notes. It gives you every formula, what it means and how it is asked. It does not re-teach a chapter from zero. Never studied the topic? Read your textbook first, then revise from this.

Every symbol explained
A formula you cannot read is a formula you cannot use. Each row says what every letter stands for and when it applies.
The mistake that costs marks
One trap per chapter, written out where you will see it.
Diagrams to redraw
Each on its own page with blank space to sketch it from memory.
Checked against the syllabus
Verified chapter by chapter against the official CBSE 2026-27 curriculum. Removed topics are marked so you skip them.
Questions
Is it updated for 2026-27?
Yes, and checked chapter by chapter against the official CBSE curriculum for this session. Topics removed in rationalisation are marked so you do not revise them, and anything NEET or JEE still tests is marked separately.
Is this full chapter notes?
No. It is a formula and revision book. It gives you every formula, what each symbol means and how it is asked. It does not re-teach a chapter from zero. Read your textbook first, then revise from this.
How do I get the file?
The download link appears on screen the moment payment succeeds, and a copy goes to the email you enter at checkout.
Can I print it?
Yes. Every book comes in two editions, one on grid paper and one clean for printing on plain A4. Your purchase email links both, so download whichever you want.
What if it does not open?
Email us with your order ID and we will resend it by hand, normally the same day. If we still cannot deliver it, you get a full refund.
How does the free doubt-solving work?
Open the Telegram bot using the link in your purchase email, which ties the bot to your order. An AI tutor reads your question, works through the steps and replies, usually within a few minutes. You can type the question or photograph it from your paper. Fair use is 50 questions a month per buyer, and an AI can be wrong, so check anything that decides an answer against your textbook.
