Hey there, You will be scoring 543 marks in NEET 2019. Congratulations on scoring such good marks and you also belong from OBC Category and really that will be very helpful to you while taking admission in any government college as some special seats are being reserved for special categories. With these marks, you can get a seat in MBBS  in government college very easily.  I will recommend you to first see the colleges available for you in your home state so that you can get a special home state quota there and it will be really best for you.
