Changing a SATII Test Date?

<p>So I'm in a pretty unfortunate situation.
I'm was planning to take the World History SAT II in June, but I can't because I'm part of this immersion trip/community service program with one of my classes. We'll be leaving on May 28th. I'll be gone for about 2 weeks.</p>

<p>Is it possible for me to take the test at an earlier date? There is no subject test for World History in May. And I can't take it in December because.. well.. I'd still be taking the subject. So I am wondering if it is possible to take it during May 15th-27th? I read on college board that I can change the test date for an additional fee, but it doesn't say any requirements or restrictions.</p>

<p>Does that mean if I contact College Board and tell them about my situation I can take the test a week before I leave? I just need to take it before May 28th.</p>
