Shrishti, 

Sorry but you can't apply for IIT barch because one needs to give Jee Mains paper 1 and qualify for Jee Advanced and then clear Jee Advanced and also clearJee Main Papaer 2 Barch and then apply for AAT nad qualify it. 

If you have qualified all these 4 papers/ entrance examination then only you are eligible for Barch in IIT. 

But you can still apply for NITS/GFTIS/ OTHER PRIVATE COLLEGES.
