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 Biology (Class 12) and the CBSE Class 12 Biology 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.
