I would persuade FOX to make another season of firefly for £30. I can be very persuasive . Failing that i'd buy an ostrich (I have very good contacts) which would distract me from my results. And then when I get them, if I do well I could do a victory lap on my ostrich (his name will be Glen and he's a battle ostrich) round the sports field.
And if the price of ostriches suddenly increased for some unknown reason, I would buy skyrim legendary edition for the Xbox 360 (as my old normal copy is all scratched ) so I can go and slaughter have a good speaking to to everyone at the college for not teaching me well enough to pass my exams.
I would buy a tiny tricycle, and train my dog to ride it, using bacon treats tied to the end of a wire, protruding from the front of the tricycle as incentive.
If he didn't learn, then I would ride the trike myself, up and down the high street, singing "Lady Marmalade", wrapped in nothing but tin foil and a drag queen wig.
Pretty sure after that I wouldn't care what my results were.
i would use it to go out and buy however many pizzas i can get for £30, and then walk around manchester giving them out to homeless people. wanted to do it for quite abit, and what better way to get over bad results than helping other people
