Hey Zoya, You have scored 457 marks in NEET 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. Yes, You can take a seat in government college but there are fewer chances for that as even you can see the cutoffs for this year are very high so there are fewer chances of yours. 

 I would personally suggest you use the NEET Predictor and explore various colleges according to your category and home state quota and choose the best one for you as this college will be your future lifeline. It will be best for you as you will be able to see the best colleges available for you at your category and your state quota too.
