If you're one of those people who need deadline pressure in order to actually start studying for the Series 65/66 exams, here you go: the Series 65 and 66 are changing starting January 1st.
Yes, new topics are being added and--more frightening--the emphasis is shifting on both exams. For example, the 45 questions on business practices/ethics is being reduced to 40 on the Series 65. The 80/20 split between regulatory questions and securities & analysis questions is changing to 50/50 on the Series 66.
So, if you were thinking of putting off the exam until 2010, I would not recommend that. It's going to take a while to see how the exams are really changing based on imperfect feedback and educated guesswork by everyone in the test prep industry. Theoretically, the existing practice questions available should be as close as they ever were going to be, given that the Series 65 and 66 outlines haven't changed since January 2004.
