Hello Aspirant,

See there is no any fixed cut-off mark that would decide which you are going to get because cut-off marks keep changing every year depending upon various factors. 
However for government medical colleges you have to score good marks in NEET 2022 like if you are seeking admission through AIQ counselling then you should not set your target less than 620 marks at least and if through state quota then it depends upon your state but still you should try to achieve minimum 580+ marks in NEET 2022 for good government colleges for MBBS even through state quota.

If you are preparing for NEET then to help you in your preparation we have some resources which you can access from the link given below :-

I hope this information helps you.
Good Luck!!
