Re: NATS Selection Tests
Again, there's not much practice you can do. You have the oppotunity to do 'Practice' tests - and if I were you, I'd do a few of them. The only way you can really prepare is to know what sort of questions you'll get. Aptitude tests really do sort those who 'have it' from those who don't. Someone with a poor education is on exactly the same footing as a PhD student.
The important thing is to not worry about it. Maybe you'll pass maybe you won't. If you don't apply you'll never know...
