Hello aspirant.

As you mentioned you want to take part in deemed dental colleges in Karnataka, but you are a Maharashtra domicile holder, you will have to take part in All India Counselling conducted by the MCC. To participate in All India Counselling  for deemed universities, you need to register at the MCC site and pay INR 5000 (non refundable fee) as application fee and INR 200000 (refundable) as security deposit (For all categories) which will be adjusted in the tuition fee if a seat is allotted to you and you take admission in the college or will be refunded if no seat is allotted to you, after the counselling ends.

IN deemed colleges, 100% seats are reserved under the All India Quota and the cut off usually goes low for these (barring a few colleges such as KMC and HIMSR). However, if you wish to take admission in private dental colleges in Karnataka or government dental colleges, you will have to participate in Karnataka state counselling. Please note that you will be a part of 15% quota and can only participate through All India Counselling for government colleges as you are not Karnataka domiciled.

Hope you have understood the difference. All the best!
