cityoflights: I'd say you should re-evaluate your situation before deciding to spend the next 2-3 years doing something that may not benefit you in the end.
During my undergrad., I had a downward trend of GPA, which is something you don't want to have... I did really well in my prereqs (aka freshman and sophomore year averaging a 3.7). Then with my junior and senior years, I had personal circumstances where I had a few C's in my science upper-division courses, the rest B's, and only 2-3 A's. My GPA wasn't that low, but it's not stellar either.
However, the important thing is I know I can perform well in science courses, and pharmacy is what I
really want to do. I'm now in pharmacy school and doing well. Most pharmacy classes are not too hard, but they definitely require a
strong foundation in pre-requisite courses.
My take: spend a quarter/semester retaking O.Chem, Bio, Physics, and see how you perform in those classes. If you can do well (B+/A- average), and you can
stand what you're studying (aka you don't feel extremely miserable studying for an O.Chem test), then keep going. BUT if you really struggle getting a B/B+ average dong pre-req courses while putting in all your effort, pharmacy school will be very, very hard. Think
4 core graduate science courses per semester (plus other pharmacy practice classes which aren't "hard" per se, but you still have to go to class and complete projects for them). There is no point in doing something that makes you feel miserable, and I know quite a few people that keep trying (which is a good thing, but not for all circumstances), finally get into pharmacy school, but then give up because they can't handle the course load. There are other options out there that, while they may not give you a "doctorate" in the end, might be a better fit for you personally.
Also, I did well on my PCAT. I've no idea how "important" it was versus the other factors (letters of rec, ECs, research), but I did get interview invitations from two schools ranked in the top 10 (so you can rule interview/personality out as factors), so I'd like to think that my PCAT score did not hurt
(because my GPA most definitely didn't make me stand out).
