When actually applying to PT school your major does not matter. You will have to fulfill the pre requisite courses which oftentimes includes physics, anatomy/physiology and calculus. Therefore science related majors will meet those pre reqs without taking additional classes.
I graduated from PT school with a class size of 50. One classmate was an English major and two did career changes from engineering , the other from a marketing job. And of course there were several biology and kinesiology-exercise science majors. Don’t think you have to go the traditional route if PT interest you. A non traditional major on one hand makes you stand out amongst so many applicants and will spark conversation if granted an interview for PT school.
In college, you may change your mind , possibly several times. So whatever you major in, if you decided PT school is for you, make sure you have your prerequisite completed.
