YF1764

I am studying aeronautical engineering in Imperial College London, and I am applying to US grad schools. There are a few questions: 1. I got first class in first 3 years, how do I report my GPA? Do I need to ask WES or other organizations for conversions? I know that some schools allow us to leave a blank, but some schools didn't say anything at all... 2. My dream schools are MIT and stanford. I got V161, Q170 and AW4.0 on GRE, and I have a 2-month aero-related internship. However, I did not publish any paper, and I don't think I can publish one before the application deadline. How big is the chance of getting into the aero MS program in either of these two schools?
