I think one of the most important factors is early application. PharmCAS is scheduled to reopen on June 15. I don't believe that they are going to actually send the apps until August (you can double check that), and if so, that gives you almost 2 months to gather your materials together. Plus, if you kept a copy of everything from last year, that will save you tons of time and headaches when entering all of it again this year. I know that some schools (Midwestern - Glendale, for instance), will create a pending file for you if you go ahead and send in your letters of recommendation, even without having your application. You'd have to check with each school on that. Glendale is one that will be on rolling admissions this year, so it's in your best interest to send it in asap.
Also, like I've posted before, if you are taking summer courses and want those grades to be included in the GPA that the pharmacy schools will see (providing you submit your application prior to January 2005), then wait to submit your application until August. PharmCAS will not let you add your summer grades if you submit the application prior to completing those classes. You would have to wait until their updating session in January. Hope this helps.
