I failed stage four sometime ago!
Was it the end of the world?
Maybe for a day or two!
Moved on stronger, more focused and even more keen to get flying.
Don't speculate, just wait, go along when called up and enjoy the experience. If you don't get in (6 cadets per month makes it),its just one of those things. You can't win at everything but keep your head up and you will succed eventually!
