Hello chaps,
Don't worry about the dreaded class 1. I think people know if they are blind or deaf, and they must expect the worst. If you are reasonably fit then it's a doddle!
One thing I will say on the EEG (this is in response to Tarmach), don't count your chickens before they hatch. Anyone can be epileptic, and you would never normally be able to find out about it. There was a guy there, perfectly healthy and a prospective pilot. Had the EEG and flipped - and that's it, a dream is over. Just as well they found out. I also know another guy who flipped when flying into the sun piloting an air taxi, the light frequency made him go a cropper!
The rest is easy! The urine test is ok too. You know if you are diabetic, but make sure you haven't had any toxins (not saying that you have) well before hand.
p.s. If you are lucky you might get the lovely strawberry blonde Irish nurse that I had!
