I have a degree in Journalism, and am now in nursing school. Credits accepted for transfer were Psych, Soc, Speech, English Comp.--maybe a few others. Do you have many Science credits already? I didn't. Unfortunately, most of the BA credits cannot be applied to the BS degree. However, I have heard that having a previously earned BA does become relevant at some point, as it demonstrates that you have taken higher level courses requiring critical thinking, and that the critical thinking competent is what the BS provides. Good Luck!
