i will appear for IITJEE 2012 ......is it sufficent 2 solve iit papers of last 10 yrs?...or do i need 2 do all d papers?

Hi Shreya,

More that enough to solve last 10 years. Only the concepts are important. Most of the concepts would be covered in the last 10 years. It is the idea behind solving the sum that makes IIT JEE diffeent. So wish you all the best. Prepare and do well.
