The interesting thing about pschool is that many programs don't even require a BSc or BA (though MANY applicants have them..)
-Some schools require the "PCAT", other schools do not.
-Some schools used the "pharmcas.org" website for the initial application and others do not.(most have supplemental applications on top of the pharmcas application, and the supp app can be pretty extensive, too- like UCSF.)
a good resource is any of the pharmacy professional organization websites, like
http://www.aphanet.org/
also, pharmacy.org & pharmcas.org are also good places to start.
The science prerequisites vary for almost every school..
At the very least: 1 year of Physics, 1 year of Gen Chem, 1 year of Ochem, 1 year of Calculus, 1 year of Bio, 1 semester each of speech, econ, and psychology are usually standards, and some schools also require microbio, biochem, as well, and some schools even more. It all varies and you have to look into the requirements for each school. Not sure where you are, but in california, there is a website called assist.org that gives you an idea of what courses are accepted as prerequisites from other CA schools.
good luck!
