Hey firstly congratulations on getting such a good score on your NEET Exam .

Yes you have a good chance of getting into a college of your choice through All India Quota (AIQ) counselling process under the OBC quota. Even if you don't get in during the first round, you most definitely will get in during the second round. Just make sure to enter the correct college codes and fill them in the correct order in your preference form. The college codes will be provided to you on the official website when the preference forms are released.

I hope this answer was helpful.
