if you dont mind, where? do you have access to world markets? of course you are not DA but is it possible over there? how do you like commission sales? anyway, I would get the passperfect disks. Passperfect worked for me. Take all of the tests and just memorize the answers. there are only so many questions they could possibly ask you, in only so many ways. mark off the ones you have trouble with and write them on a 3x5. memorize the card. go over it in the car before you take the exam and eat a good breakfast. come on man, this isnt anything new.
I also gotta take the exam soon; i was wondering, are you allowed to use a calculator? As for studying I just used the 'CBOT Commodity Trading Manual' and bought the 'practice exam' disc at securityexams.com ($99)....it seems like the exam is pretty straight forward and simple (esp if you've traded futures and spreads before).
