No ILS..... Its called PROFITIERING aka taking money off those who are duped into believing theyre getting something worthwhile for it!!!
Id advise all prospective candidates to get the info together from here, books, websites and what NATS supply and simply study it - hell do it before you even apply so its in yer noggin.
After all, thats all this "business" will do for you - theres nothing they can provide that aint free to all!!!
Good Luck to all - your future career is more honest than some
