Hey,

The qualifying marks for NEET is : 50% for unreserved category, 40% for reserved categories (SC, ST and OBC) and 45% for PWD. 

Once you qualify the exam, you can register for the counsellings. Now the cut off marks varies from college to college and state to state. The cut off marks are much higher for all India quota than state quota. For government MBBS college under AIQ, an unreserved category candidate would require around 570+. And under state quota this can be around 530+ or even 500+ for some states. This cut off marks are lower for private colleges, which are under state quota counselling. 

Please mention your marks and AIR so that I can help you further or you may check from the college predictor to know the probable colleges you might get admission in.
