I was really looking forward to this particular course, but found the technical issues with many of the lessons to be distracting. There were sound problems on a couple of the videos and I found some of the course materials hard to follow. I reported the issues as I found them, so hopefully they will be fixed in the future.
There were also some style issues with the materials. For example, in all or nearly all of the videos the Instructor took up half of the screen (I don''t mind looking at the instructor, but in many cases the materials were hard to read on my screen because they were not the focus of the lesson). The slides were almost all text, and often what was said and what was showing on the screen did not match. Finally, I am a visual learner. Diagrams, pictures, visual comparisons, charts and graphs can go a long way in helping me to comprehend the materials. Reading text on the screen does not help me to learn the materials.
Using the one quiz per hour approach (rather than 3 tests every 4 hours) combined with questions which did not always map to the course materials created several lost hours of study.
Some of the source materials were world class, but many of the referenced links were to bloggers and opinions and often the references were several years old and did not reflect current state of the art.
Finally, I had to repeatedly report one individual for cheating and it took almost a week to get the issue resolved. I don't know if it was the support staff who resolved it, or a note I sent the individual when grading his blank submission. I knew he was cheating when I saw that after I graded the blank submission, he submitted an exact copy of my work for three different exercises.
