So in summary. lets say there are 500 (pure guess) places at the next stages, if you haven't heard, I'd say you're in one of those places, with the caveat that you could drop off if more high scores come along.

There is no relative scoring throughout the process, it is all absolute scoring, i.e. against a fixed standard. If everyone who applies makes the standard, then everyone gets in (albeit with a very long wait time!).
