I'm a sophomore and college is coming soon, so I'm looking into University of Sydney. I live in Milwaukee, WI. I go to an IB School, (International Baccalaureate), and I will be not be doing diploma. Instead, I wish to drop two classes, Spanish and Chemistry, and fill them up with different IB courses. Then I would like to test higher level for all eight classes. I hold decent grades, a 3.0 and above. I'm a very good swimmer too. Is this good enough to make it into the university, or not? Also, is there anything I can do to make myself better or what kind of SAT/ACT scores I need?
