I was a TA for classes using this material. We(the TAs) sometimes come up with problems to be incorporated in it. The lecture notes are superb, I often refer people to them because it's freely available. The hw is basically"given you've learned this, can you apply them?" I found many students like this style of problems. I personally prefer the homework problems of Sariel har-Peled(who teaches in the same university, and I'm TAing for) http://sarielhp.org/teach/ http://sarielhp.org/teach/ His hw problems guides one to figure out important materials that's not covered in class by breaking it down to small steps. (Say, a hw problem that introduces parametric search) I definitely recommend solve some sariel style problems once one mastered the basic material.
