What does 8/9 and 3/9 mean?
A UAI of 100 would be extremely rare and I can assure you that those who can achieve a UAI of that level will probably make a very poor pilot. I suggest that the folk at the PSA know this too, so don't be dismayed if your UAI is between 7O - 99. As long as you've applied yourself to study you'll be fine.
As I've said to others on this thread; avoid getting too focussed on one area. Cover all bases with a sound performance and knowledge level.
Ryano's comments are spot on. If you're motivated at the right level, you'll do what ever's required to achieve your aim.
