where can i get free books for IELTS

You might try talking to a local librarian or someone at one of your local schools, and they may have books that you can borrow. I do not know what "IELTS" stands for, but maybe try running a search for the full name of the test plus "free practice tests." If you have a while before your test, consider getting a tutor to help you. If you can't find one in your area, you may be able to find one online or find an online tutoring service to go to for individual questions. Good luck with your studies, shekhar4uall! :)
