This is a time to work together. In all of the above suggestions where I’ve recommended that you reach out to teachers, that you insist on certain kinds of accommodations, the key is to be kind. Take me at my word here. I’ve worked directly and indirectly with faculty on six continents, and most of them will respond to kindness. If they know you are trying your best, they will also try their best. (Some of them are reading this right now, too.) Remember that faculty are human beings who have been caught just as much by surprise by this pivot to online as you have… only many of them are not as tech- or web-savvy as you are.
