The CBOE/Options Institute manual blows. I took the test today and I'd say 1/4 of the questions were fresh to me. Completely fresh. If you include the questions for which the material was barely mentioned in passing in the manual, I'd say I had to make educated guesses on a good 1/3 of the exam. And this after I read it over at least 4 times. Stay clear until they make more updates.
