I'm sorry to disappoint you but if you are from General category, it is unlikely that you get a medical seat even in a private college under AIQ or state quota.

However, if you are under SC, you may easily get admission in government / private medical or BDS colleges. Let me share a list of previous year cut offs to give you some idea.

Siddhartha Medical College, Vijayawada- 378 (under AU state quota for SC). But it was 554 for Unreserved under state quota. 

Rajiv Gandhi Institute of Medical Sciences, Ongole- 360 (for SC in AU area)

Rajiv Gandhi Institute of Medical Sciences, Srikakulam- 363 (for SC in AU area)

Private medical colleges had a cut off range of about 330 to 360 for SC quota whereas it was arohnd 500 to 530 for general. 

Hope that helps!
