The Application Process

I did my BBM (Marketing & International Business) in Australia at the University of Queensland, Brisbane. I was wondering how the Australia GPA is converted to a US GPA. My GPA is about a 5.5 on 7 and with most top schools average GPA at about 3.3, i am hoping i fall somewhere in range. The other parts of my application are pretty strong but I need to know so i can be confident about my school selection. Any comment would be greatly appreciated. [/b]
