Chandigarh Group of Colleges, Mohali is good but not the best college for pursuing B.Tech in CSE. This is a private college and also affiliated to IK Gujral Punjab Technical University, Jalandhar.
A college is marked good or bad by its placements and education environment only. Here, you will get a good environment to study but the placements are good only as last year's placement percentage was around 73% only. That was a decent placement score but can't be announced as the best.
