Hey there, you have scored 220 marks in NEET 2019 and you also belong to ST Category. Really that will be very helpful to you while taking admission in Government Funding Technical Institute (GFTI) as some special seats are being reserved for each and every special reserved category. Sorry to say but you will not be able to take a seat in any government college and even not in any semi-government college. I would suggest you check for government colleges, semi-government colleges, and even some good private colleges too in your state as you can get a seat in reserved quota too.

 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. As it will be very beneficial for you while getting admission there and it will display the list according to your home state and even your category.
