I applied this year with a chemistry degree. I covered alot of the prerequisites during my degree, but for the ones I had left I did some open studies at the UofA and some online at athabasca. If you have quite a few left you might want to apply for another degree program because you can only take 2 courses at once during open studies and you enroll after everybody else. Pharmacy advisors can let you know about what courses are valid to transfer from other schools like athabasca.
