Should I take CSE at B.P. Poddar or go for CSE at Heritage Institute of Technology through the management quota?

Heritage would be far better for your career than B.P.Poddar, in terms of educational facilities and campus infrastructure. The environment is good and the members of the faculty are helpful and nice. 

I have visited both of these colleges and am familiar with them. If you want to have a fantastic college experience, Heritage would prove to be the best choice for you.

It could be a bit pricey if you use Management Quota. However, HIT offers good placement for CSE. In the recent placement drive, the average CTC offered at the institute was 4 LPA and the highest was 16 LPA.
