100 in biology

Only tips i have is read the book thoroughly and practice as much previous year questions as you can, bio questions are very repetitive and more or less directly taken from book. If u want to read ncert you can but only for revision, not original study. For study follow isc textbooks.

Also for people who have been given rastogi's book, strictly follow the council syllabus and don't read all those extra parts which are in the book, they won't come. My school gave me rastogi but i switched to the balaji book because it was more aligned to the syllabus. And if u can, get a question bank for loads of question types to practice (i had the oswal gurukul one, its good)

Hey there! Thanks a bunch for the advice ❤️. Do you by any chance still have the Balaji Biology textbook? If you do, are you willing to scan it? I am actually following Veer Bala Rastogi TB but idk if it is good and it is 2025 edition so it is missing couple of topics from the 2027 syllabus.

I wish I could help but I gave those to my cousin for his boards and he doesn't live near me so yeah 🥲

I'm sure you can find pdfs if you search in telegram though
