I took a Kaplan course this past summer, and the volume of materials is a bit overwhelming. As the previous poster mentioned, Kaplan is rather serious about their copyrights over intellectual material. However, I did accidentally buy most of the Kaplan materials on Ebay prior to taking the class. I was trying to get cheap practice materials, and the file ended up containing Kaplan materials... But I ended up having access to them through the course. Go figure.
Also, if you do end up taking a course, the online one should be good enough. My in-class instruction was inferior when compared to the streaming online lectures.
