The problem I see with trying to substitute classes (IF I can find any in-person, which is unlikely) is that the courses that are online now are pre-requisites for other courses in her major.
For example, all math and chem courses are online, and she needs those now so she can take other math and chem courses in the Spring. So if I found an in-person Art class to substitute for Chem, I’d be screwing her up – not helping.
