Pre-requisite courses that can be outstanding at the time of applying are different for each school. This link lists them, but I think it’s best to check (or double check) with each school individually. I also know people in my program have told me that they applied to schools without having finished all the pre-reqs in time and were still admitted. I don’t have experience with this, and I wouldn’t recommend it, but that is what I’ve heard.
For specific PTCAS questions, I recommend asking PTCAS directly. I remember them having excellent customer service, and got especially quick answers when I tweeted at them. As for school specific requirements, your best bet is to check with each school individually.
Who else has PTCAS questions??
There are no gods in the PT application process, just professors and other administrators! But 64 hours a week is a LOT, so as long as you are able to articulate what you have seen and learned during that time, it will be a big benefit to you. I think it is especially great that you’ve experienced multiple settings as PT can vary quite a bit from in-patient to out-patient. Here are two previous posts I’ve written about clinic hours before.
