<p>He cannot retake. A 760 for maths 2 is not bad - it is not great for Harvard, but not bad. The reason the percentiles differ so much is that the collegeboard tries to keep a 700 in subject a the same as a 700 in subject b</p>
<p>How can that be you may ask when 700 in Korean may be the 20th percentile whereas a 700 in eng lit may be the 95th?</p>
<p>It is because some subjects are very self selecting - most people take maths 1, so the people who take maths 2 are Good math people. People who take physics are good physics people. Whereas eng lit - the most popular sat 2 test - is taken by everyone because it sounds easy (myself included).</p>
<p>SO</p>
<p>760 in maths 2 == 760 in Korean == 760 in lit even though the percentiles may be 75, 50, 95… Due to the collegeboard correcting to self selection in the test takers</p>
<p>So, the 660 is not good. The others are not bad, but not great. Since you cannot retake I would submit them all</p>
