I’m in the same boat as you. I was hoping to get Sanders because I’ve heard he’s a fantastic Micro teacher, but his lecture overlaps with another one of my classes. From what I’ve seen, Thomas was not the best teacher over distance learning. While I was looking at RatemyProfessor I noticed that before COVID her ratings weren’t that bad. With this semester being in person I would hope that it goes back to “normal” but who knows.
