I would like to inform you that it is absolutely not that difficult to crack bitsat without attending any coaching classes. These are a few books that are good. Arihant's or Cengage's BITSAT Explorer book for the topics which don't match the JEE Main syllabus. BITSAT English Proficiency and Logical Reasoning by Disha Experts.

Hello Vatsal Tandel, if you want to crack BITSAT 2020 without coaching then it is going to be very difficult for you. There are serious practice books through which you can practice number of numericals to crack BITSAT exam for every subject. Like for physics you can go with HC Verma for irodov. For chemistry you can go with Arihant and DC Pandey.

Hello Vatsal

Buy Arihant's or Cengage's BITSAT Explorer book and do the topics which don't match the JEE Main syllabus!

BITSAT English Proficiency and Logical Reasoning by Disha Experts

If you are preparing for JEE advanced(or even a high level of preparation for JEE mains) then believe me, there is no need to do any sort of preparation for BITSAT except on 2–3 days before the BITSAT exam.
