yes, it appears that a favourite game of the examiners is 'what am i thinking of'. you have to kind of admire them, they always seem to have a way of making the next question more ambiguous and arbitrary then the last. the exams are more of an excersize in answering cleverly worded questions than a true test of the subject matter.
a trick i used for the CAO's was to go on the casa website and print off the CAO checklist and put that in the front of the CAO's. its pretty effective as an index, not sure if it's technically allowed but no one pulled me up on it. don't think there is something for the CARs though.
