Dear Iswarya,  AP Medical seats are categorised into 3 areas abd depending on a Candidate's locale, a canfidate is considered local for a particular area. In 2018, under BC Category, the cut offs for various areas have been as follows:

SVU: 473

AU: 484

Under SVU, the private colleges that you have a chance at are:

Sri Padmavati Medical College for Women
Narayana Medical College
PES Institute of Medical Science and Research
Santhiram Medical College

Having said that cut off changes every year and is dependant on various factors like no.of seats available, no.of candidates appearing for the exam, top NEET score and difficulty of the exam. Meanwhile, please visit this page to check the cut offs for each of the above mentioned colleges:
