What should I opt for, DTU Mechanical or PEC (Chandigarh) CSE?

Both the above colleges are really good, so you needn’t worry about that front. You need to first decide which field you have an interest in. If you really have an interest in CSE, only then you should go for PEC. Otherwise, mechanical is a very good branch. Moreover, DTU is known for its mechanical department.

If you are really interested in either of the branches, you should go for it, irrespective of the college you choose. You must first check if you are interested in coding/ development or automobiles, etc. But if you can’t judge your interests, you should go for DTU because Delhi life would offer you more exposure and opportunities. DTU Mechanical is an old, developed branch that is very proud of its heritage. 

The table below gives a brief comparison of the courses.

You may ask a DTU as well as a PEC student for their reviews and then decide which college you would like to go for.
