Ok but how long will that take for him to actuallly get hired, after he starts in september?they'll accept you.
Sept 2014, you're going college
as @kp404 said, put on a nice outfit, comb your hair, go down there, explain your situation to them (no job prospects, GCSE's) you want this and you want to turn your life around.
Don't wait till September!!
Go now so you get in there early.
Sit with someone who will talk you through your options, you will get a place so that's in the bag.
From now till September, find a job (or sit on the coli) but you know that's waiting for you.
