I just wouldn't try to evaluate the personality questionnaire at all, or else you could mess it up completely.
When I did the test, it seemed to be riddled with contradictions, and difficult questions, but you cant second guess the staff answer.
I remember one question asking me if I like art to which the answer was no, a few pages later I was asked if I had any paintings, which I answered yes, if you try to analyse it yourself, you would worry thinking that you are contradicting yourself, but infact you are not.
Just fill it in with the first answer that you feel is true and dont dwell on it.
