Once again a question posted a million times!
The summary of all the threads with the same question is be yourself, there's no way you can lie your way through it and there's no reason to. They won't pick up on an individual question and go 'Look what (s)he answered here'. They just place your results on a chart (i think there are five different categories) and see how well you fit.
If you are extreme at a category they might pick that up and ask something at the interviews. Was given a 'speech' by one of the examiners during my aptitutes and it went along the lines of..."we had one guy that scored extremely high in the risk-taking category and when he was asked about it in the interview, he said that his parents own a bungee jumping club" (or something like that). Don't know how much to believe of that..but..anyway!
There are 300 questions. There's no time for you to go back and check what you answered in a similar situation about 50 questions ago.
Just relax and answer truthfully.
Hope it helps.
