Hii
You will be able to participate in West Bengal MBBS counselling only in All India Quota. All India quota gives only 15% of the seats of that paritucular domacile. Therefore it is advisable to take part in your own state. However for private college in management quota or payment seat it is upto your choice of whatever college u choose. Only thing is that you need to have enough money to pay to them.
Don't lose hope !!
Best of Luck !!
