Not too easy. Not too difficult.
John Stewart is an excellent professor, he has all of his hand-written lecture notes online so that if you miss a class you never behind, in addition to this he and his wife created a textbook that accompanies the course which he provides, free of charge, online to his students. The labs for his class are structured in such a way that they always help with comprehension of knowledge regardless of skill level with the subject material.
The section pertaining to circuits was particularly interesting and not difficult to understand the applications.
