If I were in your exact shoes, this is what I WOULD DO. I would probably take a year and enroll as a full-time student somewhere, CC or even better a 4-year university. You need to prove to the admissions committee that you are able to handle a rigorous courseload. I would take 4-5 classes a quarter/semester including more advanced science courses as well as re-take certain pre-reqs such as o-chem if you did especially poorly, and ace everything. I'm talking 4.0, anything lower and it's not as impressive, plus you're trying to raise your gpa FAST. The good thing about this is if you do well in your courses, you can ask a prof. or two for a fabulous LOR. I would also try to get involved on campus, fit in some cool volunteer work to beef up extracurriculars and, of course, rock the PCAT(highly doable).
A Master's degree or some other type of post-bac program would greatly improve your app. also but only if you do really well there. I personally don't think YOU NEED to take 2, more likely 3 or 4 years out to enroll in a Master's program if what you really want to do is go to pharmacy school. Take one year to work on that gpa, then apply. If you don't get in that year, keep working on that gpa, and apply again.
As my friend put it quite nicely.
try = possible fail, no try = absolute fail
However, what was the reason for the low grades throughout undergrad? I think you will have to diagnose the reason for that to ensure that it doesn't happen again. This is definintely an uphill battle and depending on the other aspects of your application, even if you get closer to 3.0 gpa, nothing is guaranteed but I think if you really really want to be a pharmacist, there's no harm done by applying in a year and trying.
A lot of pharm. schools out there value an upward trend in grades and if you can do extremely well from here on out, I think YOU CAN make up for that low gpa. 👍
