I took School of PE for the ME PE and while I did pass, I thought their classes were a bit disorganized. The biggest thing for me was they have a chat room to ask the instructor questions. What ended up happening was certain people would fire 20-30 questions about even the most trivial stuff that could be answered easily if they'd look in the MERM and/or notes. Examples that would take 3-5 minutes ended up taking 10-15 causing the instructor to speed through the remaining material. When confronted by our other peers about how their behavior was interfering with the pace of the class, they merely dismissed it as "we all learn differently." The kicker was they told us to get private tutors (when we weren't the ones asking all the questions).

I ended up studying on my own for a few classes, only staying to get attendance credit. Also, you could tell they use the same set of slides for all of their instructors. Essentially the courses can be a huge YMMV. In hindsight I would have opted for classes with a bit more rigor and structure such as PPI.
