Generally no. They are in the program handbook, which is given to you at orientation. For me, that was already after quitting my amazing job at a top hospital, moving, signing a lease, paying a deposit/tuition...
At that point, you're already in.
No, they would not work with me. I was not the only student this happened to either. Sorry, I'm not disclosing the name of the school.
After this whole thing happened though, I reached out to/looked up almost 20 of the top programs and asked about their grading policies. Some of the program coordinators were really rude, which surprised me (Maybe a red flag for those programs). Some said they regularly dismiss students for this reason. Hurray? Some program coordinators were really amazing and helpful/more transparent (schools I should have been applying to). In hindsight, I would have done this before applying to schools, but I did not even know it was a thing I needed to be concerned with.
