If I became a part-time student and take 5 (instead of the normal 4) years to finish my degree, will it affect my chances into professional schools? I'm looking more into physiotherapy, but if you know anything about other healthcare jobs, that willl help too.
Let me know. Thanks.

Different schools have different rules. The rules will be clearly stated somewhere on their admissions website, so I'd recommend you do the research for the schools you're interested in.

I know for social work it doesn't matter if you're full or part time, they just go back to how many credits you have until it equals a final year or final two years. Just check out the schools you're interested in applying. You can always call or send an email if you're unsure.
