<p>Multivariable and Linear Algebra, since they are not AP courses, fall under the Pre-matriculation Credit policy of the Trinity College of A&S if you want them considered as college courses. Basically the course has to meet the following criteria to receive credit:</p>
<p>1) were taken on the college campus;
2) were taken in competition with degree candidates of that college;
3) were taught by a regular member of the college faculty;
4) were part of the regular curriculum of the college;
5) were taken after commencement of your junior year of high school;
6) were not taken on a study abroad program completed prior to matriculation at Duke–restriction does not apply to transfer students if such credit was granted at the former institution;
7) yielded a grade of B- or better;
8) were not pre-calculus or English composition courses; and
9) were not used to meet high school diploma requirements.</p>
<p>All of these criteria must be satisfied according to the PMC policy for credit to be considered. And you have to send in your college transcript, and 2 additional forms, one of which goes to your high school for certification and the other goes to the other college for certification. If the multivariable and linear algebra were taken as part of a high school curriculum, the credit is probably not possible and you’d have to settle for placement which should be easier to get. </p>
