Hey there, you have scored 466 marks in NEET in Tamil Nadu 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 get admission there in a government college and you can even apply in other states like Karnataka and you can get admission very easily there.
