Hello Aspirant,

See NCERT textbooks are must have books for JEE-Main examination but that are not sufficient because it will clear your concept only but will not teach you how to apply it in the real problems, so you need some reference books to have proper practice because in JEE-Main the candidate should have proper understanding of concept and also he/she should know the application of those concepts in different questions so honestly saying NCERT textbooks are not going to make you clear JEE-Main 2022 with good marks because now very few days or even around a week is left only for JEE-Main 2022 session 1.

But don't worry still you should try to give your best and now I would recommend you to solve previous year question papers and some sample papers of JEE-Main which you can get from the link given below :-

I hope this information helps you.

Good Luck!!
