Hello,

Ritik IIT Kanpur is always the best and above any college to choose, but coming to your subjects in iit kanpur  b.s. chemistry ,job will be decent but not that high as a CSE branch in punjab engineering college.PEC is good college for CSE with a decent placement,so you may go for pec cse but you have a dream for iit and passionate about the subject than surely go for iit .All the best
