I am getting civil in iit d and iitk...also mech and elec in iit roorkee...what should i prefer..placement wis?

civil in iitd . just last year i had to go through all this. you may opt chemical dua or 4 year. it is also excellent package wise. i opted chemical dual in delhi on 1334 i am happy with that. iits chemical is better than civil. chemical involves thermodynamics not chemisry.
