Generally, a bare minimum score is at least a 50%, but even with that score your probably going to want to apply to lower tier schools to have a chance. On average, a decent score to shoot for is at least a 70% composite. I mean, if you do apply with this PCAT score, you definitely want to make sure other parts of your application are absolutely stellar. Like a 3.8 GPA or higher for example, like TONS of volunteer experiences, TONS of leadership experiences, experience as a Tech, and are able to explain your PCAT scores thoroughly within the admission essays or personal statement. Also, lets say that you got a 20% on your first PCAT, and this time you got the 43%, that will look good for Admission Committees, but again, with this score, you want the rest of your application to be absolutely stellar. Schools have reported ranges between 25% and 99%. I guarantee the guy with the 25% had a stellar rest of his application and a very good reason to why he got that score, in addition to proving he can handle the rigor of Pharmacy School.
I got a 70 percentile on the PCAT. I got a 98% in Chem, 85% in Math, 80% in Bio, Verbal 33%, 4% in RC, and a 4 on the writing. I got into the #3 Pharmacy School in the country, University of Minnesota - Twin Cities!
