Hi,
You may refer following colleges according to your rank(considering general category):
Presidency University, Banglore
CMR University, Banglore
A M C Engineering College, Banglore
GITAM University, Banglore
Nagarjuna College of Engineering and Technology, Banglore
R R Institute of Technology, Banglore
Cambridge Institute of Technology, Banglore
This is according to the previous year cut off ranks and after various rounds of counselling, this may vary.
Hope it helps.
