Dear Swaapnika, Cut offs change every year. We do not have 2019 data yet. But AP MBBS seats are categorised into AU,SVU and OU areas. In 2018 under State Quota, the cut offs for varipus Categories for General Category have been as follows:

AU: 533
OU:526
SVU: 517

Now cut offs change every year and are dependant on various factors such as no.of Candidates appearing for NEET, no.of Candidates qualified, top NEET score and difficulty of the exam. For you to get a seat in 2020 under General Category, anything less than 550 will be difficult. You should aim for 550 and more.
