sir currently i am solving my institutes questins and a book called dcpaney in physics o you think with this much preparation i can score a good rank in iit

Solve the institute questions and do much practice and after the completion of a particular topic,solve previour yrs IIT papers on that topic.Well,DC Pandey(Arihant) is good but it contains a lot of errors.I think good practice,clear concepts and good revision  reserves your place in IIT.All the best.

u should tell us ur institute's name first of all....the quality of study material depends on the institute.n if u dont hav good quality study material..u cant rank very good....:(

use h c verma - concepts of physics.... this book has been used by many students and is very good.... m recommending this book as i too m using it and it seriously is a good book...
