Man I just hate powerpoints in general.
I kind of wish it was like back in the old days where they would have to diagram everything on a blackboard. All of the illustrations, fancy ways of organizing things, etc. makes it more complicated.
Also hate having 23 hours of class with little guidance on what you are expected to know for exams. Some professors give you notes to read for each lecture plus chapters plus powerpoints. Others say just check their powerpoints. Still others list objectives you need to generally know. I feel like half my time studying is figuring out the most efficient way to study.
