Kindly mention the CRL rank while asking such type of question ,. and in obs rank 3448 , u can get iit patna , and iit bhu probably with biotech and chemical branch .. in 3rd round councelling ..
so, it completely depnends on you which stream intrest you more ,
so, try your luck in Josaa councelling .. if got any iit , except the new ones like iit bbsr , iit goa , iit tirupati . etc .
then take that iit , every branch are good i can say , but stay away from textile branch, and if that is the case that u are getting biotech and textile in any iit , then wait for the top nits , u can get their in 3rd or spot round councelling ,
and the most preferred branch is comp. sci and electrical , civil andmechanical are also good ,
REST DEPENDS ON YOU ,
fill the form of josaa and lock the seat as soon as possible ,
ALL THE BEST ..
