Hello aspirant

First of all i am sorry , but your question is not clear . Please mention which specific book do you want ...since there are many authors who have written books on JEE and there are various different publishers for the same . And also there is no such compulsion that every book is there on google in the form of pdf which is accessible to all...Some books do not allow anyone to share their content for free , so the only option is to purchase them . Also for those which are available in pdf format you can be easily search them on google and get free access to the same

Hope my answer helps

All the very best!

Hello aspirant ,

The main syllabus for jee is the ncert textbooks. If you are asking about the reference books for jee many online websites and apps are providing you with free textbooks and course material. Websites like crack jee, iit books, Vedantu, Byjus, etc are some of the many from which you can refer.
