Pre-PT?

I recently got accepted to Sociology as a transfer in COLA; my 1st and 2nd choices were Psychology and Health and Society. I’m fine with majoring in Sociology itself, I’m just worried about completing my prerequisites for PT school. Even if it is a BA degree, would it still be possible to take additional science classes to fulfill my prerequisites?

How did you get accepted into a major you didnt apply for?
