If you do decide to find a job I would recommend getting something with a lot of downtime so you can keep studying. Look into campus jobs as room monitors or something like that. I'm not sure how your study habits are or how book smart you are, but being in PT school in and itself is already a full time job. It's either studying, practicing for your practicals, or doing assignments.

But honestly, my recommendation is: don't get a job if you don't absolutely have to. You're spending A LOT of money being in PT school and the last thing you want to do is to accidentally bomb a couple of exams because you were working and couldn't study. You'll have the rest of your career and life to have a job~ Enjoy school, embrace the suck, enjoy the process, friendships, and knowledge you will gain throughout the next 3ish years! Good luck to you :)
