<p>There’s no difference. Liberal Arts schools just call the degree “BA”. It was amusing writing BA instead of BS on my grad school apps, but seven of the ten schools I applied to happily accepted my “BA in Astrophysics, anticipated May 2008” from Wellesley, so you’ll be fine.</p>
<p>I’m a little bummed though, I wish I could have the BS, MS, PhD combo, but hey, the school I’m doing the master’s/PhD from gives SMs anyway.</p>
