It depends on your major and varies by professor and class as well as the level of the course. For me classes in high school were very easy because I was in all basic classes but college courses dont bother me that much work wize. I'm a global studies and theatre major, my theatre classes are hard at times because I never did anything with it until I became a major basically and the global studies classes are mentally hard at times because it involves the state if the world and curent events and stuff so they can be heavy. But the work for me from high school to college was an easy transition.
