<h1>1: Getting a 2400 is very difficult, even for someone with English as a first language. I am making an assumption that English is not your first language, and if you make mistakes with punctuation and so on, you would be ecstatic to get a 2100. You do need to take practice tests to see how you do. Sign up for the College Board online SAT course and try it.</h1>
<h1>2: It doesn’t matter if you get a 2400 in terms of aid, at top colleges anyway. Conversely, some colleges consider if you need FA if you are an international student, and it is a mark against you if you do need aid. Once you are admitted, aid is determined separately.</h1>
<h1>3: Please read the College Confidential site before you post such a silly question. It is silly because many people post many similar questions, and no one has any answer but “it depends”.</h1>
<h1>4: And read the CC site more, to learn about which students get accepted and which don’t. I have a friend who went undergrad to school in India, and to Johns Hopkins for her PhD. In the US, it is easier to get into graduate school and the prestige is still there.</h1>
<p>From the College Board: “382 out of 1,547,990 college-bound seniors received a 2400 in 2010”. I would find it interesting to see how many of them were not US citizens.</p>
<p>Another anecdote: my son got an 800 on the math section of the SAT, no questions wrong. He has several friends with much better GPAs and better test scores, but not ONE has gotten an 800 on math. Even the kid with the 2380. Even the kid taking multivariate calculus (most of them are in AP Calc BC). So ONE perfect score in an area that my son’s friends are very very good in out of 20 kids my son knows in his honors and AP classes. Now you start figuring out you need 800 on math AND 800 on critical reading AND 800 on writing. It is not as easy as you might think. </p>
