AI isn’t good enough to grade written responses. If your referring to chat gtp and the like, they meant to be factual. Also online multiple choice homework can suck awfully depending on the course; physics comes to mind in this scenario since it requires an answer with precision and matching units to mark the homework as correct and that can make it really difficult to resolve and even if the teacher sets it up for partial credit if you get it right after attempts, if you can’t figure it out it is a 0. That physics homeaork destroyed and consumed my entire life lol
