What kind of job are you looking for? What kind of experience do you have right now?
in reply to [Slightly OT]: Is certification worth it?
If you already have some experience in programming etc, you could possibly get an employer first and let them pay for any courses/exams. You might not make a lot of money, but it'll probably pay more than fast-food and I would guess it'd be more fun :-)
If feel you need a certification, you can probably buy some books, study at home and do just the exams for a lot less than 8000 pounds. For instance, IIRC the sun java certification exams cost about 250 euros, add a couple of hundred for the books and you could save yourself a lot of money. Dunno about the MS exams, though.
