Yeah, it's possible. As long as it's not taking up TOO much of your time, and you'll know if it does. I'm working part-time, probably only until this summer, as full clinicals begin in the Fall. I work no more than 6 hours a week throughout the weekday. But you seem to be working more, so just see how it works out for you, although some would discourage from working at all during PT school.
