As I’ve said to other readers, when to enroll in PT programs is a personal decision. Most students enroll after graduating, but others take time off to work, gain additional experiences, or, like me, they didn’t decide to become a PT until after working in other careers.
If you don’t get accepted, I recommend asking for feedback from the schools that have rejected you and gaining additional PT experiences before reapplying the next year if you still want to be a PT.
