It wouldn't be fair on the other candidates to reveal anymore than what you have been given. How often do you go in for a test having known the questions before? Maybe sounding to some extent selfish but you already have an advantage of extra days to prepare and since essentially I am in competition with you /all of the other candidates I am not going to give you some inside information. Would find it strange/ slightly unfair if anyone did.
Besides they explain on the day theres no point cheating your way through the test having known the questions etc... because you'll be wasting both yours and their time at FTE when you struggle with all the exams that they thought you would be able to pass.
