Hey there

Yes ofcourse, as per your expected marks it is highly likely for you to get a government collage seet

The NEET cut off varies from year to year, state to state and as well as college to college. It also depends on the Quota you are applying through as well as the Category of Admission. Government and Private Colleges have cut-offs of their own. 

In state quota, you will surely get government seet

But in all India quota, you need more than 550 to be that sure

As you are OBC category, it further increase your rank.

Just keep yourself updated with the counceling and the schedule. All the best!
