I didnt do anymore then the assigned readings out of glannin, but as far as advice goes, start your outlining now for the class. When you start going through your class notes, everything might come together. I seldom have even the remotest clue about what is going on in the class till after I begin outlining. Also, take advantage of outline banks in understanding the concepts. NYU has a great one. There are some 50-90 page outlines on there that are amazing. While I do not recommend using the outline, many of the students really organize and break down a concept when putting together an outline. As a result, you can read their outlines on the concepts your really dont get and it helps to figure it out.
