How many Neet marks required for this college?

Could you please specify which college you are talking about?
In general, a score in excess of 550 is required to get a decent government medical college via 85% state quota and a score in excess of 600 to get a decent government medical college seat through 15% All india quota
In general,the cutoffs for reserved categories may be 20-30 marks lower than unreserved category students
However the cutoffs may vary and depends on the level of the question paper and the relative performance of the different candidates.
If you have some specific query,you can let me know
Hope this helps
