Frequently asked questions

Is the Biology-I textbook available for free?

Yes. NEET publishes the official study material/textbook free of cost. Use the official download link above for the authentic copy.

Is the Biology-I textbook enough to score well, or do I need extra notes?

The official textbook is the core — most exam questions are set directly from it, so read it thoroughly first. Add concise notes and solved past papers for revision and exam practice rather than switching to unofficial books.

How should I study the Biology-I textbook chapter by chapter?

Cover the high-weightage chapters first (use the exam pattern as a guide), make a one-page summary per chapter, and immediately solve a few past-paper questions on it. Active recall beats passive re-reading.
