Dear Viraj, 

15% quota is applicable for some private college and some colleges do not have 15% quota. As you are from maharashtra ,many private medical colleges won't be included in AIQ and seats would be allowed only for the students who apply by state quota. 

Same case Karnataka, you would have choices of some colleges in AIQ but not all since some colleges are not included in AIQ.

The list of colleges can be checked from the official mcc site as the registration starts under the category of participating institutions. ALL THE BEST FOR YOUR COUNSELLING!!
