Hey SELINA! 

Greetings! 

Nice to see you again :)

I would like to say that alone NCERT won’t fetch you 325+ marks in Biology. You should definitely read NCERT Biology very thoroughly and try to clear and grasp maximum basic concepts, examples, names of scientist and which country they belong to (I am not joking on this).NCERT should be on your finger tips first. 

The other books I would recommend you is

1. Trueman’s Elementary Biology VOL I & VOL II
2. Dinesh Objective Biology VOL I , VOL II & VOL III

3. Bio NEET Cengage Publishers

4. Biology, MTG

5. Aakash or Allen materials do have collection of good objective bits.

Tip: Practice as many MCQs possible . Atleast 150–200 MCQs per chapter.

Thank You.

Do upvote if my answer helps you :)

Best of luck! Cheers.

Hello dear student, 

I have taught students preparing for neet and was a student too . So I will suggest you books that I personally like and which I felt cover maximum part that comes in NEET . So the best book so far in biology is ncert . I would suggest you to read ncert like anything. Don't skip a single line as the maximum portion directly comes from ncert. Other than this solve last year's question papers. While you can buy previous years chapter wise  topicwise book from Arihant. It's the key to crack exam . If you are in school then I will suggest you to keep a copy of truemen . Its a very good book .

I hope this was helpful to you. 

Best wishes
