Courses Completed: Calculus II

Review: This is the most interactive and productive online course I have ever taken. I had taken calculus before but never understood some of the underlying concepts until I took this course.

Review: Course was good and fast. I don't like math so I can't say it was fun or anything. Grader was very nice. Software was ok.
