The instructor, Felienne Hermans, is very a very enthusiastic and engaged teacher. Also the TA team was very involved in the discussion forum. I thought the format of the lectures, Felienne standing full size in the foreground and the spreadsheet in the background was less ideal: sometime it was difficult to see which commands were typed or which buttons clicked. My main criticism is the lack of graded exercises in the course. One learns a software tool by doing and in such the course did not entirely succeed: the graded tests were very minimalistic (small in size and not very challenging; some "challenge" questions were ungraded). Compare e.g. with MIT's Analytic Edge, which does a much better job in this respect. If you have worked with Excel but want to learn some neat tricks, it is an OK course though, where you certainly will learn some new things.
