I believe the content of this course was good. However, the instructor for the class had a very heavy accent and, unfortunately, I could understand very little of the lecture material. To make matters worse, the transcripts of the lectures were obviously done by someone who, like me, could barely understand the instructor! The transcripts contain so many errors that, in many cases, they are virtually unreadable. I quit listening to the videos around Module 4 or 5 as it was just a waste of time. I used the PDF ppts and struggled with the translations to try to learn. That did not work in the cases in which the PDF ppts were absent (at least twice). Finally, I am not sure how others feel, but the fact that the instructor used hand-written examples instead of technology (Excel, maybe?) to show work is absolutely unbelievable. It was made worse by the fact that his handwriting is very, very bad and it was impossible to read what was written. Truly a bad course experience. I don't quite understand reviews that say otherwise.
