I was in a similar situation, and I am not sure what your reasoning for your low GPA is, but for me it was a ten year health crisis and an abusive situation, which I addressed in my essay. I actually went back to school with a 1.9 (!!!!) GPA, but the community college I started at allowed replacement grades, so I raised my overall cumulative to a 3.43 by the time I got accepted, and have a 4.0 from my last 60 hours and pre-reqs. However, I still had several Fs outstanding from years ago, and OTCAS calculated overall GPA as 2.8ish, I think. It took me 4 years of work to turn my situation around and finish by undergrad, but I did it with the explicit purpose of OT, and made that clear to programs. I have got into every program I applied to so far. My advice would be to raise your GPA. Honestly, it is possible for you to turn it around for yourself and get in, but it will take a lot of work on your part (you almost definitely won't get in with under a 2.9-3.0, likely not with under a 3.3 unless you have good reasons and a killer essay). Other than that, get EXTENSIVE experience observing OTs in as many settings as possible, and get healthcare experience if possible. Good luck, I promise if you are dedicated enough it can be done!
