Don't get too hung up on academia, the academic requirements for NATS are pretty standard. I found that knowledge was only a small part of stage 1, things like spacial awareness and diagramming are things you can either do or you can't. This was even more true of Stage 2 where no knowledge was required, it was purely a test of cognitative ability. Some people can do the stuff, some people can't.
What was the stat on here before? 90% of applicants fail stage 1?
To answer your question NATS will ask you for more comprehensive personal information if successful @ Stage 1.
