My school covered it in the last semester. We did 2 full days of EKGs. You need to start out with basic EKG rhythm interpretation, and after you know it well, then you can move to 12-leads. 12 leads its pretty much the same as basic interpretation, but you have to realize what parts of the heart you are looking at. Looking at what the OP posted as what is included in this class, and considering it is $700, I wouldn't waste my time. If your school doesn't cover it, and you get hired into a unit with tele, then you can take a class through your facility, have co-workers teach you, get books, etc.
Try picking up "Rapid Interpretation of EKGs" By Dr. Dale Dubin. It is the best book out for learning EKGs, and is written in such plain english, that you can teach yourself with this book. It will start with basic A&P and how the electrophysiology of the EKG works, and then move into basic EKG rhythm learning, and go into advanced stuff and 12-leads.
