Hello aspirant

Yes, for ICAR Examination, ncert books are best.  You can prepare well as it covers the entire portion of Physics Chemistry and biology for class xi and xii.  You should solve  model test papers also apart from this. But I think it will not be sufficient like  for Biology , you should know examples in each and every subtopic in plant and animal physiology . For physics ncert will be sufficient.

Hey

NCERT is best to choose to prepare for exams when using reference book for better understanding. Prepare with NCERT books and also practice questions from question bank, exemplar, ICAR entrance books. This will help you best in your preparation.

Hope I could solve your query.

Feel free to drop comments.

Thank you!!!
