Jesus Carrasco
I took Prof. Carrasco for both Span 1441 and 42. I would say you definitely can't slack off in this class. It's hard. I took online so I can't speak for the in-person class but I can say a lot of it was on your own. Lots of reading. There wasn't much info in the lectures until the 2nd year. However, he was VERY kind and helpful if you emailed him.
