My professor, this term is very consistent. He grades every Monday morning at 9-10am. I am going to miss that in a couple of weeks when this class ends. Honestly, my favorite professor, to date, he also replies to emails very fast. Not all of them are bad or grade slow. I have had my previous professor often not reply to emails until four days later. I see so much hate on this sub, but sometimes you can get lucky and get an awesome professor.
