This is indeed an awesome course. Unlike other online courses I have taken where the better students provide the lion's share of help on the forums, in Calculus One, the staff do an excellent job of monitoring the forums to help out. Just as often they comment on the less formal side discussions as well.
And Dr Fowler is indeed an awesome educator. His frenetic enthusiasm serves well to hold the students attention for what can sometimes be a very dry subject. My hat comes off to him.
The course provides an interactive problem solving site hosted by Ohio State U where one can practice solving problems. There is also a free .pdf textbook where one can do the same.
In sum, I recommend this course without reservation to anyone interested in a first yet in-depth exposure to calculus.
Great math teacher, wonderful course materials, very helpful course staff. Best example of how an online course should be. Course provided excellent tools to study - free textbook, platform for doing exercises, great quizzes and exams.
