There is more than enough info on the stage 2 tests on here, if you are really desperate then check out the sky test which gives you lots of prep which you can pay for, or look it up on WIKI. The purpose of the tests is too see how well you can cope doing unfamiliar tasks under pressure and how fast you can learn new rules. Everybody improves with practice and it is unfair to have some people who have practices and others who have never seen anything before (which is the way it should be)
