Hello Aspirant,

See as you have not mentioned your NEET Rank and score so it's quite difficult to guide you with an accurate information. But as you have mentioned that you got a college but you are not satisfied with it so I would recommend you to go with the seat upgradation means you can participate in further rounds of counselling to get better seat and suppose if you will not get any seat in further rounds then also this seat will be kept reserved for you. For this you have to visit the allotted college and pay the required fee and if you will be allotted a seat in further rounds then this seat will automatically be cancelled and the fee will be refunded to you.

You can also use NEET College Predictor to predict your admission chances in different colleges :-

I hope this information helps you.

Good Luck!!
