How to prepare myself for the IIT-JEE ?? I am in class 9th and I am really worried ?

First of all dont be worried !! as you are at basic level of the preparation so just can join either good reputed institutess basic foundation courses..or u can try solving the tough and conceptual questions at your level..cz iitjee is only about the test of your deep knowledge in the core subjects.please dont try the study the 11 and 12 syllabus as it will only confuse and demoralise you..
and last but not the least believe in you !!
best of luck !!
