<p>Which SAT Subject Tests should students take?</p>
<h1>To satisfy our application requirements, applicants must take two SAT Subject Tests. Students should not submit two Subject Tests in mathematics to meet this requirement. Candidates whose first language is not English should ordinarily not use a Subject Test in their first language to meet the two Subject Tests requirement. . Applicants may wish to convey the breadth of their academic interests by taking tests in different subjects. All students are encouraged to submit additional Subject Tests (which may include one in a students first language), Advanced Placement or International Baccalaureate test results, or any other evidence of the breadth and depth of their academic accomplishments. </h1>
<p>look at it in another way… when all else are equal colleges could favorably look at a student with better AP scores as AP scores (not the original intent) and SAT II scores (more so) are used to validate your school grades.</p>
