Dear Aryan, last year cut off for most of the colleges lied between 530-540, so you have pretty much higher chances for getting a seat in GOVT college.
Only Patna Medical College had the cut off greater than your score - 552.
Here's the list of colleges -

• Anugrah Narayan Magadh Medical College, Gaya-533
  
• Darbhanga Medical College, Laheriasarai-533
  
• Goverment Medical College, Bettiah-534
  
• Indira Gandhi Institute of Medical Sciences, Patna-536
  
• Jawaharlal Nehru Medical College, Bhagalpur-535
  
• Nalanda Medical College, Patna-537
  
• Sri Krishna Medical College, Mazaffarpur-533
  
• Vardhman Institute of Medical Sciences, Nalanda-534
  

Also, the cut offs are expected to increase this year as the exam was but easy. You can wait for the exact cut off.
All the best.
Feel free to ask for any query.
