The waiting time for results isn't so bad because you spend the whole time winding down from the effort of the day. It's a relief to know it's all over and there's nothing else you can do to influence the result.
Most people didn't even stay around and just got the email a few days later. They just handed out the bit of paper with the cutoff score for each test and your mark for each test and if you passed each of the 6 tests you will get to to the psych. profile questionnaire and interview.
Cutoff points for each test are meaningless because the calculation of your score is all done by the computer behind the scenes. You get progress scores as you do each practice test so you have some idea of how well you're doing.
The maths questions at the start are all a variation of time = distance * speed - all using aircraft speeds. And as someone mentioned, in the last minute of the test, just randomly select answers for all the questions you haven't answered because you don't lose poitns for wrong answers.
