I have a degree in health and physed...when i was going to school PT was another year of schooling plus it was very hard to get into...i only had a 2.9 gpa(didnt really give alot of effort) so i decided to go into the fitness field instead...and did well for 8 years, but the last 2 have been shitty. PT does seem like a safe job....people always get hurt and dr's send them to pts often
no way youll get accepted with that gpa. if youre serious, find a school, see the dean of the school for sciences, see what classes you would have to retake, what route to go. they will probably tell you no chance right then if thats what they feel. if youre serious, thats what i would do.
and for going to be a nurse, again, absolutely no chance with a 2.9 gpa. thats just a ridculous recommendation.
