I am never going to anything taught by non-working professionals ever again. No matter how heavily they're endorsed, it always seems to be a flop for me.
(To give you an idea of how badly this guy flopped: I attended every day of high school. I did my damnedest to go to every college class, no matter what. After paying for the class, and both of us being pretty obsessively into getting our money's worth... neither I nor my studiomate wanted to go for the last day.)
