Amenhotep,
My sympathies to you, but if its any consolation, the fact that you know what to expect from the tests next year can only make it easier for you.
You know that all the people reading the other thread are going to say.....
.....Maybe you should have worn a suit.......and cheap jokes along those lines(I wouldn't dream of it obviously).
Best of luck next time and bear in mind that many, many people got in second time.
Myself included, and I didn't wear a suit to the test day either.
