It must be daunting having your children study away from home.
Navigating universities is like navigating government - complicated and unfriendly. I say this as a university drop out who didn't know who to talk to when my ship sank and my family was a continent away.
My only suggestion for your daughter is seeing if the same courses are available with a different prof. I'm sure every university has a complaint process but following that through to its eventual end may only compound agony.
Parenting young adults means never knowing if you're doing too much or too little.
