I decided LSE over Cambridge..and my reasons were totally valid, so that person who said you would be "BONKERS!!!" , is, sadly, one of those ill-informed, ignorant people who automatically decide that the best university for everyone would be Cambridge, just for the fact that it is Cambridge. Anyone who knows even a little bit about the academic world would know that LSE is internationally renowned, some reasons being different reasons than that of Cambridge, one of them being the emphasis on careers and vocational training. I hope you make a choice that reflects what you want, not what everyone else wants(and it does often seem like it!).
