In my opinion you can prefer NCERT books for JEE objective. Around 80% of questions from chemistry in the JEE Main exam will be from NCERT directly or indirectly. If you would have read NCERT properly you would be able to solve 65% of the questions easily. Not only referring books you have attempt mock tests. So that you can score easily in JEE mains. In Careers360 also you can attempt the mock tests. There are many websites you can search.

Here I will provide the mock test link below :
