What actually decides your Biology marks
Half the paper. Botany and Zoology together are worth as much as Physics and Chemistry combined, and they are won on recall.
This is the half that decides ranks, and it is the half that flashcards were made for. Reading a chapter is not the same as being able to produce it under time.
Practising it by chapter
Our bank is tagged to all 83 chapters across the three subjects, so Biology can be practised one chapter at a time from past NTA papers, rather than three questions at a time inside full papers. Your accuracy is tracked per chapter, which is what turns "I am weak in Biology" into something you can act on.
The method is the same whatever the subject: see how to revise a chapter you keep getting wrong.
Every Biology chapter
Each one has its own page: what it covers, what it carried in the 2026 paper, and sample PYQs where the chapter allows a clean text question.
