I got 503 marks in neet 2019 I am from ap svu region. can I get A category seat in our region

Dear Sujitha, you havent mentioned your Category. Neverthless in 2018, the cut offs for various Categories for SVU area have been as follows:

General Category: 517
BC: 473
SC: 403
ST: 395

With 503 marks you have fair chances at getting a seat in a Government Medical College if you belong to BC/SC/ST Categories. Having said this cut off changes every year and is dependant on various factors like no.of candidates appearing for the exam, no.of seats available, top NEET score and difficulty of the exam.
