Dear Udaya,

You can get the Tommy Concepts which are asked in Q-Bank style via the link at the top of the page. There is another set in the free download section. I heard that both are not yet updated so there are a bunch of questions/answers on the standard valuemd pages. Still, I heard that there are many who passed USMLE 1 by reading only the Tommy Concepts along w/ some reference books and mastering them entirely.

Kaplan may be better since the format is timed, and you can do random questions by subject, and they record % correct and so forth. But, The Tommy Concepts are free, and it is tried and tested. Study very hard. I am sure that if you put your heart and soul in, you should pass.
