Hi jet.
Try looking for one of my posts back in January called 'NATS initial tests'.
I submitted my form by email directly from getting the form off the internet and it didn't do me any harm.
I got the invitation to the first tests in November last year, sat them on Feb 9th, have my next interview on March 16th and, if successful, would be starting training in July.
There is no accommodation in the college from what I've heard, but loads of digs in the area.
Good luck!
