Disclaimer: I am a newer student and have done my program's summer semester, but not a full-load year round semester yet. Many people in my program work, most (including myself) work around 10 hours a week but a couple do more. I find even 10 hours to be difficult, but others make it work, especially if getting straight A's is not something super important to them. I would recommend speaking to your program and asking about the requirements for your specific school, as many are different. Also be honest with yourself on how good you are with planning out schoolwork, completing things ahead of time, and whether you will have the stamina to attend class, go to work, and do a few hours of school work when you finally do get home. It also might be difficult to maintain a rich social life, or a good sleep schedule. I don't mean this to be totally discouraging because some people must and do make it work, I just think (based on my experience and talking to others) that it will not be an easy undertaking! OT school is rigorous and exhausting on its own, so you don't want to burn yourself out! Also, fieldwork II is a full time experience that almost definitely won't allow another job. However, you know yourself best! Consider asking what the class schedule is like, it seems so far (for example) that my program limits class to three days a week, which makes it easier to work, but those are long days! Best of luck!
