International student :P

<p>Hello everyone... I have a couple of questions, if someone can answer me I'll be totally grateful :P</p>

<p>So, I'm an international student, and I was wondering, how do they know how good my GPA really is? In my country, they measure grades on scale from 1-5 where 1 is the lowest and 5 is the highest.. I'm finishing my junior year now, and through this 3 years I had all 5, so my GPA on our scale is 5.00.. So, I have the best GPA that I can have, but, how do they know how good that is actually cause the educational system in US and here are different..? </p>

<p>I'm in mathematical high school, so I guess that's a plus, (4 years of physics with 4 classes per week, than 4 years of physics 8 classes per week, 4 years of programming 4-5 classes per week) but how does that compare to students from USA that took APs etc...</p>

<p>And yeah, about the SAT II, (i'm totally nervous, i'm takin the test this saturday :)) ), is it good to have three subject tests, or they don't even look at the third one?</p>

<p>thanks to anyone who replies :D</p>
