I treated the course like any other course and seriously under estimated it's difficulty. The instructor is hard core and the text is no easier then he is. PLUS, it's an interactive class which means he's in another town with another classroom and we can only hear his voice and see his PowerPoint notes on the TV screen. Sometimes when he speaks fast it sounds like a bunch of mumbles. Sometimes I find myself blaming the communication problems but I could have taught myself from notes and text...that's where all the exam questions derived from.
