Absence of Problems to Grind?

Lately I've noticed for csc148 compared to my other courses is that 148 lacks a list of material to grind out a some point.  Maybe that is supposed to be incentive to branch out and learn more but I have to wonder why there isn't really a "Extended Learning" tab of some sort with problems to do or extra content to read.  I'm sure there is plenty of material on the internet easily accessible by Google, but I'm just wondering as to why there isn't some sort of more focused outlet for all my computer science motivation.
