Dear Jitin, 

You need to clarify your question a bit more. Now, assuming you are asking the cutoff of SC category for NEET 2018, then it was 96 marks (an equivalent of the 40th percentile of this year). This means that everybody in SC category who scored equal to or above 96 in NEET 2018 became eligible for the admission and inclusion in the counselling process of centre and state. 

Let me know if you are seeking the answer to something else. 

Good Luck!
