Hey there, you have scored 434 marks in NEET and you also belong to BC 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 you can first check the cutoffs of the government college and apply in the counseling according to that marks. Rather than looking for colleges out of your state go for colleges in your home state as it would be very helpful as you can get admission in state quota too. 

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.
