is it really necessary to refer reference books for physics (NEET)? -may I know why ncert is not sufficient even though syllabus is based on ncert textbooks??
No, NCERTs are not sufficient as they are good only for concept building. They don't have enough questions and examples to practise.
However, NCERT Chemistry is sufficient if you Mug up all the Intext Questions, Examples and Exercise Question. For Physics and Biology you need to refer to reference books as the key to cracking competitive exams like NEET is practising as many questions as you can.
Some of the reference books you can refer to are -
- IR Irodov - Physics
- HC Verma - Physics
- Trueman's Objective Biology
- RC Mukherjee - Chemistry
- OP Tandon - Chemistry
