Well, one of my friends is studying at BIT Mesra and according to him, it is a very good college especially for CSE. 

• The teachers here are very good and experienced in their subjects. Professors like Arun Sir and Mustafi Sir are great and helps the students a lot in completing their projects. They are always ready to help anyone irrespective of their branch or year. 
• There are coding matches held every Saturday at the campus and many workshops are also conducted by ACM which turns out to be very profitable for the students. These are great interactive ways to learn and practice new things.
• The placements are also amazing as top companies like Flipkart, Amazon, Practo, Coupon Dunia, Goldman Sachs, Snapdeal visit the campus for interviews, and offer packages more than 10 LPA. 
• Companies like Microsoft, Amazon, and Goldman Sachs also hire interns from the CSE branch.

If you want to know about PEC Chandigarh, then ask someone who belongs to that college like a college alumnus or a student studying there. They can provide you genuine information about the college.
