Guys, I'm at where you are pretty much at. I have been doing the OG book and I'm almost done. I noticed that when I did the first 100 or so questions from each section, I was around 85% to 90% correct. However, when I got close to finishing the entire section my % that I got correct dropped closer to 80%. Make sure you do all the questions. On another note, although I don't take my test in Dec, I take it Nov 28th. So it looks like I will be the first one to take it in this thread.
I am really worried because although I got a 620 in the Kaplan Diagnostic, I'm getting mostly 530 scores from the Kaplan CD tests. ahhhh!! I need to break 600 on the actual test!!!! SC on the Kaplan tests are hard!!
