Hello. Yes, definitely you can participate.  But at the end you will be liable to pay some distinct amount, as a difference for participating in both cases.

You can lock your seat in whichever round you are satisfied. For more concrete information, check the information bulletin present on the MCC counselling website to know more details about this issue.

Hope that helps!

Dear Aspirant,

Yes for sure you can participate in All India Quota Counselling and State Quota Counselling simultaneously. Both these counselling are separate and if you have domicile of a particular state then it is recommended that you go for both counselling. It increases number of chances to get a seat. Coming to the next point, if you already got a seat in All India Quota Counselling and if you have not accepted the seat then it is fine but if you have accepted the seat and reported at the college for admission then there can be an issue. So to sum up if you haven't accepted the seat alloted to you in All India Counselling then you can surely go for State Counselling.
