Could I get rescinded if I get one potential D? I’ve had quite a few family problems and health problems this semester… so I’m not sure if my excuse would be sufficient. Should I go talk to my counselor?
I think be rescinded is pretty rare. Schools have already invested in you. They don’t want to lose you. So call the school and explain the situation to them. Ask them about possible difficulties you might encounter if you get a D. I bet that will alleviate your worries. They are very used to this happening-it does for them every year many times over-its only new to you. 
You’ll feel better after talking to them.
