This is Vivek, in my final year B.Tech. at **IIT Bombay.
Some of you wanted tips on how to prepare for IIT JEE, the answer is 99% perspiration 1% luck.
One should be very serious about the way he/she prepares fot IIT. Just doing lot and lots of problem wont help. You have to recognize the pattern which IIT JEE follows, the level of toughness they give and the level of toughness you can handle.
What I found was that doing previous years JEE problems help a lot in understanding the complexity of the job involved.
Apart from that, go to some good tutor, which might help in solving your personal doubts. Follow good books, like I followed H.C. Verma and Irodov for Physics, Morrison and Boyd for organic chemistry, Krishnas publication for inorganic and physical chemistry, and Asit Dasgupta for maths. Also recently a publication called Arihant publication had published quite good books. These will help all the aspirants a lot.
Finally devot time for studies and be true to yourself, and I assure you will clear JEE
Wishing all the JEE aspirants all the best,
Vivek.
