I am in two classes (1 and 2), and my 1 professor never answers emails or holds office hours now that we're online. There is also no TA. Oh well, there's nothing I can do except include this information in my review at the end of the class.
I happen to know that my 2 professor has taught 1 sections in the recent past, and she attends her office hours without fail. If I give precedence to any student hoping to learn 2 during my professor's office hours, then is it acceptable to attend with the intention of getting help for my 1 class?
