My personal opinion regarding this question is that one must determine his or her priorities first. If he/she desires to get out into the workforce as soon as possible, then one should pursue going for two years. In those two years, decent GPA, volunteer, and extracurricular activites/pharm. job should be maintained. If you can do well in with your GPA and fortify that understanding with a high score on the PCAT in all areas, then this will leave little doubt in the school's mind regarding your academic abilities. Mix this with a pharm. tech license, I don't see how you wouldn't get in.
Also, take into account that in four years, the competition for getting into pharm. school will be even greater than today. I can see more people pursuing bach. degrees then to get in. However, most people with bach. degree don't hold 3.8, 3.9 gpa's. But if you work hard in those two years and take a full load of courses each quarter/semester and get A's, then in my opinion, you should get preference over the bach. degree holder because you were able to accomplish the task in a shorter duration with greater success than a bach. degree holder would.
