<p>From Dartmouth website:
“You may apply for Early Decision even if you have not yet taken two SAT II: Subject Tests. You must, however, take two SAT II’s no later than January of your senior year. These test results will be used in further evaluating the applications of deferred Early Decision applicants and for academic placement of accepted candidates.”

<p>As for placement, as far as I know SAT II subject Tests are used for placement/waiver of Language requirement like Spanish or French. As for subjects like Math , Chemistry and History placements are made using AP scores or IB.</p>
