Hey Simran, you have scored 502 marks in NEET and your rank is 48006. You also belong to OBC Category as well as the muslim minority. 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 yes you can get admission in good colleges in Kerala too in management quota too. But first, look for the cutoffs of the government colleges and semi-government colleges too as it might be low this year so you might get a seat easily. 

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.
