Hello ,

As your query is you want to know whether the cutoff merit/rank would change due to percentile in MHTCET Examination for SC Category. I would like to tell you that the rank cutoff or the merit cutoff for different caste or category is different, that is totally based on your community or the category to the which you belong, and because of that purpose is it varies from person to person so based on your community SC your cutoff will be counted based on the cutoff for SC category. 

Further, if you have any other query regarding the purpose you can let me know in the comment section below I can help you with that. 

I hope your query is solved.

Thank you.
