I would agree with the previous poster - your GPA's are similar to what mine were and your GRE's are really good so the vast majority of schools would consider you a viable candidate (IMHO). Just focus on additional and varied observations because the schools really like to see a variety of exposure to the different PT settings. While doing those observations, try to develop a good relationship with the PT's so that you can potentially call on them for LOR's. One thing that I found somewhat difficult was finding a professor to list as an LOR contact. Not all schools require it (a few of the ones I applied to did require it) but I struggled with that only because I went to a large undergrad school and the student-professor relationship was tough to develop.
