I have a question!!!

No, idea. If it's anything like MD/DO, 2 semesters of biology, 2 semesters of physics, 2 semesters of chemistry, 2 semesters of organic chemistry, 2 semesters of english, with a sprinkling of one semester of math, and one semester some kind of social science.

You need 2 semesters of physics, english, and chemistry for pretty much any science or engineering major, and at least one semester of math too. So, I'd start on those if you still haven't decided what you want to do.

 

some PA programs also require A&P, while med schools do not. that's really the only difference i've noticed...

 

some also prefer microbiology...

Here is PCOM's PA program prereq list:

Here is Desales' PA program prereq list: (very highly rated..)

I would study something that I could see myself doing in the case of not being able to be accepted to either type of school.

Not to be a wet blanket about this but most freshmen premeds don't make it to the finish line. Always have a backup plan.

 

bunch of quitters...

 

There's a PA forum which might have better answers.
You should know that in addition to required coursework (which you can get from the programs' websites), many PA programs require significant clinical experience such as EMT work. They accept many types of experience, but they expect much more than 1 or 2 afternoons a month shadowing some clinician.

 

There is an actual application site for PAs (I am way too lazy to look it up) but I do see you have mentioned both Pennsylvania sites on there so I will plug King's College into that mix (one of the top rated PA programs on the east coast). I would find that website and look for the answers there (again, far too lazy).
