Hey there, you have scored 321 marks in NEET and your rank is 226069 and you also belong to OBC Category. Really that will be very helpful to you while taking admission in Government College as some special seats are being reserved for each and every special reserved category. With these marks it might be difficult but you can get a seat in veterniary college. 

I would rather suggest you check the colleges available for you at these marks at College Predictor at Careers 360 only and it will be very helpful for you while getting a seat there. It will be very helpful for you as it will show the best colleges available for you according to your category and even home state rank.
