How to revise with it, page by page

Day 1Page 1: the marks map, ten must-know facts and a two-minute self-check.
Days 2–4Pages 2–5 one at a time; close the page and redo its traps before moving on.

Day 7Re-read only the lines behind your misses, then attempt the textbook exercises.

Use it alongside the textbook, not instead of it.

What went into these seven pages

Written from the primary documents, not from other people's notes:

  • NCERT Biotechnology (Class 12) and the CBSE Class 12 Biotechnology curriculum 2026–27.
  • Audited twice before printing: gpt-5.4 + ChatGPT. Every flagged line was checked against the NCERT textbook and fixed or kept with the book's page; where the book itself misprints a value the kit says so. AI reviews are editorial aids, not official certification.

Original revision material; not an official CBSE or NCERT publication.

Questions

Is it only for the last week before the exam?

No. It is a cheatsheet of the important points, formulas and facts. Keep it on your phone and use it all through your preparation: before a mock, when a topic slips, and for one full read in the final days.

How do I get it after paying?

It's yours the moment the payment clears, and you come straight back to this page with Download and Read buttons. It stays in your ProSyllabus account.

Will the kit be updated after I buy it?

Yes. We regularly correct and improve our kits as syllabi, notifications and exam patterns change. Each time you download from this page you get the latest version, at no extra cost — so check back here from time to time, and download it again before your exam.
