Hello,
Ya it's a very good book but at this time you don't need it as it contains many data which are unnecessary.You must complete NCERT book first and after that you can study op tondon for chemistry.Please solve previous years questions to get a basic idea of how the questions comes in jee mains.
All the best!:)

It is a good book to understand the theory and concepts but for JEE Main and BITSAT you need to work beyond Pradeep.

You can use OP Tandon for your prepartaion.

To score good marks in chemistry make sure your basics are clear. Give extra attention to the topics which carries more weightage in the exam. Refer previous year questions to understand the level of the exam. 

You should also solve MCQs for your practice. 

 

Good Luck!!

Hey

Pardeep's is not a book that you should start now (especially considering the time left). It contains a lot of unnecessary data and does not provide one with - clarity of concept. I would recommend you to go through NCERT once. 
After this go for mock tests and analyze them on daily basis. It will help you gain confidence.
Here, you can check other competitive books considered best for competitive exams.
