.....to know what they are asking as there are quite a few tricks on exam questions designed to get you to fail
Absolute rubbish. For a while I was employed by the CAA as a consultant on the CQB.
I weeded out the questions and answers which were ambiguous and substituted them with ones which were clear and in proper English.
The new questions which I put into the CQB were in the same vein, and there were many.
You will only perceive questions as "tricks" if your knowledge is insufficient and/or you do not understand English.
