@Richjonesy - It depends on what info you're looking for.
If you would like to read about FEAST - simply check out wikipedia (
FEAST test - Wikipedia, the free encyclopedia). There's pretty clear info about tests.
I've got only one advice - DO NOT prepare for feast and dart. It will show you are predisposed to be an ATC or not.
The only thing which can be improved before taking the test is English language, but if it's your first language there won't be any problem
If you would like to find some info about ATC, there are really many pages about ATCO's role and the whole ATC services, just google it
