Hello aspirant,

Unless you make changes, it is more than sufficient. I would advise reading the NCERT carefully and fixing all of its issues. After that, the resources from a decent coaching institute would be sufficient. If you keep trying new things all the way through and then take the exam, your performance will be horrible. However, if you focus on just a few things—NCERT, coaching materials, and JEE questions—and review them three or four times, I can assure you that you will do well on the test.

While D.C. Pandey is very beneficial for Advance preparation, if you are simply interested in the MAINS, skip the LEVEL 2 SUBJECTIVE. For the JEE Mains, DC Pandey is effective. Although the difficulty of the questions in JEE Mains won't be any higher than in DC Pandey, if you really want to get excellent marks, err on the side of caution. It would be best if you studied HC Verma as well since JEE Mains questions could come from any subject covered in the course material. If concepts are unclear, theoretical inquiries may confuse you; thus, give HCV some time. Once you do that objective workout, your performance will improve.

Thank you

Hope it helps you
