Course help?

well normally they want at least B's for engligh and maths at gcse (no matter what subject you choose) and as long as you make their minimum grade requirements you have a chance of getting in.
Also to stand out, make sure your personal statement is top notch

Are you really interested in the East European Studies bit? Because from what I can gather they're really picky about that.

I am not completly obsessed with it and to be brutally honest i am doing it do get an Economics/Business degree from UCL.

However, saying that it does not mean i will not put 100% into it.
I have been to the EU Parliament twice, from winning competitions so hopefully that while shine through on my PS and when/if i get an interview i can research everything i need about certain aspects/areas.

Though on UCL's site they do mention to show your interest in Russia especially, however going into detail about that, i could put my other offers at risk so hopefully my EU parliament experience will do me justice

Russia is clearly not part of the EU though That doesn't really communicate an interest in Eastern Europe specifically. A couple of lines on that at least shouldn't harm your other potential offers, but then I'm no endorser of doing a degree you're not interested in as a back door to a "UCL Econ" degree...
