Comedk counselling will commence from 1st july and then rank wise accordingly. So you need to register for the counselling in comedk beforehand. 

Regarding the colleges you can get admitted to based on your comedk rank you have a lot of options~

Bangalore Institute of Technology, Bangalore

Dayananda Sagar College of Engineering, Bangalore

Nitte Meenakshi Institute of Technology, Bangalore

Acharya Institute of Technology, Bangalore

But among these options Bangalore Institute of Technology will be best. As per my opinion according to your rank you can easily get the branch of your choice in this college.
