HELP PLEASE: SAT Subject Tests in Jan?

<p>Hey guys, I just took the II's in Dec. and got a 630 on Lit. and a 500 on Math. I'm ok with Lit but I know I BOMBED Math I. I'm not applying to an Ivy or anything, and the only school I'm applying to that needs them is BU... but it's my top choice!!! Should I retake Math I, and maybe add in US History (and a retake of Lit.) as well? Or do subject test not count as much as the SAT I's (at least to BU) and I shouldn't be freaking out?
ALSO, I can't find on their site if they even accept scores from the Jan tests!?!?</p>

<p>Obviously I need to register ASAP so your advice is soooo very much appreciated.</p>

<p>BU just does not say (or even indicate) last test date accepted. So only way to actually determine is call or email it.</p>
