I've bought a lot of history, philosophy and economics courses over the years; they've all provided pretty close to a full semester's worth of lectures. Wish they were a bit longer per class to get into a bit more detail. The subject matter is broken out well for each lecture.
The course guides are great; no need to not down the titles of books to delve deeper. Sets and editing are very good.
Never had a billing problem in year's of purchases.
Professors have a slight political tilt either right or left, but nowhere near the point of pontificating of forcing their outlook on you. They have a deep understanding of their topic.
