Can a third "meh" SAT Subject Test hurt you?

<p>I intend to apply to several top tier institutions (Duke, Dartmouth, Yale, UPenn, possibly Vandy), some of which allow score choice, some of which require full disclosure, and all of which require 2 subject tests.
My SAT subject test results are as follows: US History 760, Literature 720, Math One 640. From what I understand those first two scores should be sufficient, but that last one isn't really Ivy caliber. In order to take advantage of the College Board's 4 free score reports I had to send my scores <em>before</em> I knew my results. As such my Math 1 score was sent to institutions which allow for score choice, which may not have been ideal.
Some schools (like Dartmouth) only consider the best 2 subject test scores, at least according to their website. But is it possible that this math score could hurt my candidacy for some (or all) of these institutions? If so, is it worth retaking the Math 1 test in December/January to fix it?
Thanks in advance.</p>

<p>Of the schools you list only Yale and Penn require all scores and both use two highest subject tests for admissions. Dartmouth and Duke also use two highest subject tests if you submit more than two. Vandy does not require but will consider SAT IIs submitted if they help you.</p>
