No brother frankly speaking looks a lot difficult. The competition and cutoffs have increased this year by more marks. Even last year the person with your marks had got private colleges - Konaseema Institute of Medical Sciences and Research Foundation, Amalapuram , Great Eastern Medical School and Hospital, Srikakulam , NRI Institute of Medical Sciences, Sangivalasa in AU area as their cutoffs were around 502 itself. 

PES Institute of Medical Science and Research, Kuppam , Santhiram Medical College and General Hospital, Nandyal and Apollo Institute of Medical Sciences and Research, Chittoor had cutoff 499,498 & 496 respectively last year in the SVU area. All the government MBBS colleges were above your marks. 

So things look difficult for you this year. 

Best wishes. Thank you.
