Extremely informative, however I just wish there was more hands-on learning rather than just watching videos. Nonetheless, it is still a great course worth taking.

This course had some REALLY bad presenters, and others who were EXCEPTIONALLY good. The problem with the incompetent ones is usually that their bad grammar, syntax, AND pronunciation (!!!) detracts from their capacity to convey their knowledge, so the listener/student spends far too much time just trying to answer figure out "What the hell is he trying to say!?" rather than absorbing the meaning of and context for the information being presented. In short, the presenters who totally wasted my time were: Elio Echeverria, Ken Gonzalez, Warren Araya, and John McLaughlin - all of whom engaged in countless unnecessary repetitions and non sequiturs, and whose subtitles were a pale reflection of what they actually said. Thankfully, Joe Speno, Jude Lancaster, and Adam Seibel were excellent communicators, and their videos WERE a pleasure to listen to. On balance, the good presenters' efforts were overshadowed by those of their incompetent colleagues. The lesson you should take away from this? A SUBJECT EXPERT IS NOT NECESSARILY A GOOD EDUCATOR!
