Mike....
First of all Congrats on getting into USC. Now as for your question... UOP vs. USC. Well... here's the low down. USC teaches your "pharmacy" earlier on in school. SC is one of the few schools that have a first year externship program. During your first year, you are ceritified to administer immunization shot ( eg flu shots , Hep B, TB...etc) and you practice giving shots at local pharmacies or at health fairs. You are also trained in many disease states such as hypertension, diabetes, cholesterol ... During your second year, you have IV rotations. USC is the only school in california that provides you this training!!! And it is up to date to the current government safety standards. During your fourth year you have some awesome clerkship rotations. USC is one of the few school that allow students to travel abroad (japan, hong kong, europe...) and out of state to do your clerkship. Not to mention the various dual degree programs offered PharmD/MBA, PharmD/JD PharmD/MPH etc... USC has also been around for 100yrs!!!!!! and has a great alumni network that actually care about you!!! (i got many job offers from SC alumni ). USC provides student with awesome academic opportunites/experiences not available at other schools.
Now the discussion about the passing rate.... i have to agree with BMB... i doubt the 2.7% is statistically significant. If you want to play with numbers... you can always say... at USC only 5 failed while at UOP 8 failed... that changes how you read things.
But honestly.... if you're lookings just based on academics... both schools will get you your pharm.d and you will pass the board exam. The bigger question is... what do you want to get out of pharmacy school? I think USC will give you a better experience. But you have to ultimately decide which school will make you happier.
PM if you have any more questions!!
