Hello,
I feel this is enough for scoring 60+ but you must be completely known with these books and the questions in it. Moreover, there are many big books for reference, if you are gonna write this year you won't be able to complete atleast half of those books of RD Sharma, etc. Well, these are very good for reference.
Good luck.

For JEE Mains:
Physics: SL Arora
Maths : RS Aggarwal
Chemistry : NCERT
For JEE Advanced:
Physics : HC Verma
Maths : RD Sharma
Chemistry : OP Tandon and Arihant.

No, because they give to right the particulars, so that no mistake is done. So, when computer reject, then they check throughout and try to find out the student, so don't worry wait for results.

If your aggregate in PCM is above 60% (general), you are eligible. If you belong to OBC category, you need 50% aggregate in PCM and for SC/ST, more 4-5% relaxation.

whatever is taught in higher secondary. thats enough.no coaching required if you can do this.
