Which college is better for a B.Tech in CSE? I am getting CS in BIT Patna, Galgotia Engineering College Noida & Dayanand Sagar College of Engineering in Bengaluru.

I would suggest that you opt for Galgotia Engineering College. As per the experience of a few of my friends who are currently enrolled in one of the courses at the institution offers good campus life, infrastructure, facilities, fee structure, and an ideal environment for learning. 

In comparison with the other two colleges mentioned in the question, Galgotia College is better for almost every aspect mentioned above. The members of the faculty are well educated with over 10 years of experience in their respective fields. 

The table below shows the highlights of Galgotias University placements 2020.

Going by the above factors I will say Galgotia Engineering College, Noida is better than BIT Patna or Dayanand Sagar College of Engineering, Bangalore.
