Hello dear student, 

Please be clear with your question. What does cut off date means there is nothing like this. There are cut off marks but cut off date ? 

As far as I am understanding you wanted to say cut off marks or last date till when counseling will go ? 

I am attaching a link if you mean to ask cut off marks for neet 2019

I hope this was helpful and if this is something you didn't ask for them please be precise with what you ask and ask again.
