I'm Australian but have gone to a high school abroad. I've been accepted to Johns Hopkins University. It will cost $65,000 a year for a four year degree. I would be studying math and economics. My ATAR equivalent is 99.95 and if I go to Aus, I'd do USyd or UNSW Combined Law and econ which will cost lwss than a third of what it would take to go to the U.S. What do you think I should do?
