Any one attended a United Worlds Colleges?

<p>HI im interested into applying to get into a UWC for my senior year, from what a read and heard its a great school education that provides the IB diploma and a chance to study in another country and meet new ppl also many many others things. What im asking is has anyone attended one ?,(and if so what do you think you did make yourself apeal to them more over the others) what were the pros and cons of attending one-----or applied and didnt get chosen , is it really that competitive ? what gives someone a better chance to get selected.--Any info. would be nice.</p>

<p>thanks alot</p>
