Hello everyone, I'm fairly new to this whole forum and I have been reading through the posts here and realized my application this year certainly needed improvements if I am to get accepted into PT school (my sGPA more specifically). So i was just wondering if there are people here who have gone back to school after graduation to upgrade their courses and if taking 2 or 3 courses can actually have a significant impact on increasing acceptance chances? I guess im just a little worried of not getting in and I dont really know how common it is to reapply a second or maybe 3rd tim
