<p>Unlimited,</p>
<p>A 2100 SAT is essentially the minimum to get into a lower Ivy league school (a school like Cornell).</p>
<p>Quick tutorial here:</p>
<p>Top schools in the US:
Ivies (Harvard, Yale, Princeton, Columbia, Dartmouth, Penn, Brown, and Cornell), MIT, Stanford, Caltech, Franklin Olin, Coopers Union, Amherst, Williams</p>
<p>Next level:
Northwestern, Vanderbilt, John Hopkins, Notre Dame, Georgetown, Duke, Emory, Rice, UC Berkeley, UCLA, Michigan, Washington University at St. Louis, Virginia, Tufts, Chicago, North Carolina, Boston College, USC (Southern California), Carnegie Mellon, Middlebury, Pomona, Claremont McKenna, Wellesley, Barnard, and Reed (and maybe one or two others I left out).</p>
<p>Only the schools in the first list offer large financial aid to internationals (essentially almost free at all schools except for MIT, Stanford, and Caltech, where you will have to pay big bucks). The schools in the second level list offer some aid, but it is very limited and will be even more limited for internationals, since they know you may not repay once you leave the country-so they won’t give you much in the way of loans.</p>
<p>The other thing you need to know is that these schools (all of them, not just the first list) usually have a class of students that is made up of no more than 10% internationals. This means that a school like Yale, for example, which has a total of 5,000 students and admits about 1800 (in order to get 1,200 who will actually attend) will usually admit no more than 180 international students at the most. This means that they will admit maybe 2 to 3 students from Singapore at the most.</p>
<p>How difficult is it to get into a school like Yale? Well, over 25% of the students they admitted last year had SAT scores that were 790 or higher in Critical Reading, 790 or higher in Math, and 790 or higher in Writing. Since the internationals need to be near the top of the class, this means that you would need at least a 750 in each one of those to have a chance (or, in other words, a SAT score of 2250 +). Fortunately, not every school is that difficult, but you see my point.</p>
<p>I think you should try for the lower Ivies (Cornell, Brown, or Penn) where they would pay your tuition if you were admitted, as well as some of the schools in the second list I gave above if you can afford the tuition costs–or if you think you can get a job while here to make enough to pay most of the costs. Keep in mind that most of these schools, because they are the best ones here, are also the most expensive ones. Sorry, but that’s just the way life is.</p>
<p>Good luck.</p>
