To get admission in AFMC Pune, you should score a minimum of 550 marks, the cut-off for 2017 was around 560-570. Please note that previous years cut-offs are not applicable for your admission.
- Admission into AFMC Pune is also dependent on your medical fitness that will be assessed at the college. Also, there is no OBC quota as such.
More than worrying about marks and ranks, I suggest that you focus on the preparation for the exam. 
Here are a few tips for NEET preparation: 
- Ensure that you are thorough with the NCERT prescribed textbooks, so that you have a strong foundation to tackle the questions. 
- Solve papers in a mock exam format towards the end of your preparation. Analyse them as well; outlining the strengths and weaknesses. 
- Plan your studies. Make a schedule of the topics you want to complete for the particular day, so that you don't waste time on deciding what to do. Don't keep the schedule rigid. 
- Ensure that you are enjoying from time to time. Maintain good health as well. 

Thank you.
