but that's the minimum for top ten mba. if you go to lbs, then that's definitely not enough. but it's highly possible that that amount is only about your 10 month salary after graduation. maybe some people without work experience can study mba, but i guess not top 10. in addition, you will find yourself very embarrassed if all people around you have great experience while you don't have.
I'm quite confused about LZ's objectives, looks like your ultimate purpose is simply going abroad, if so, why MBA? It's too tough for people w/out any working experience. But why simply going abroad? To marry a white mid-class male?
