Which is the best college for CSE in terms of placements, study and exposure?

First of all if you are a cs undergrad you don’t have to think about your college placements.You can get a job in any company in off campus drive.You just have to work hard.You should repeat three steps Eat,Code,Sleep. Don’t think about college placement.
One great example is Anudeep Nekkanti sir.
In reference of these colleges jaypee solan has a good reputation,being a student of jaypee noida i know this.
Just one suggestion: Learn coding as much as you can.
Best of Luck.
