Dear Arun
We at Careers360 constantly strive to give the best every students wants for and for easy choosing of the college. We had given rating to every college by considering placements,  infrastructure, education etc.,  and according do that DTU is very good, thapur is at, 2nd place.
With my personal experience too,  I can suggest you that dtu will be the best college.
If you have more doubts,  comment here.
All the best.

All three are good. In terms of rankings, DTU is the top ranked one followed by Thapar and last PEC. However the rankings are overall for each institute. One cant say that for CE these are the best. That would be a wrong assumption. So if you get in any one of them, they are good places to study in.

Hey

As per the Careers360 ranking, 
DTU, Delhi is the best college among the three.
