Civil Engineering

You must try for All India category in Nirma University and as you're scoring 80,000 rank in Mains I would also suggest you fill up the Bangalore Institute of Technology form lest you don't get admission in Nirma. Nirma also provides NRI category for 15% of total seats available. But that costs double of the regular fees. All the Best and yes feel free to ask more queries.

Here I suggest some good colleges for BCA-Christ University, Acharya Institute of management, Bangalore University, Presidency college Bangalore,
And for Civil engineering - New Horizon College of Engineering, Vijaya Vittala Institute of Technology, MVJ College Of Engineering, BMS College of Engineering.
