Going by previous All India cut offs and your rank, you may decent chances in Medical Colleges like:

SC Medical College: Anatomy

Guru Gobind Singh Medical College:Pharmacology

Byramjee Jeejeebee Medical College: Bio Chemsitry

Meenakshi Medical College: Opthamology

Kurnool Medical College: Physiology

Having said that, this is 2019 data and cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, difficulty of the exam, and no.of seats available for each specialisation.
