Hi dear,

Hope you are doing well!

Now let's get to your questions.

It totally depends on what you gonna pursue if Engineering first preference should be Coimbatore campus then Amritapuri  and Bangalore campuses which will be almost equal.

If your course preference is b.tech in Mechanical, CSE , ECE , EEE ,AERO ,CIVIL then Coimbatore will be the best in terms of placement too followed by other campuses.

All the best!
