Is there a thread going (or an old thread) of past Supplemental App. Questions?
Here are the schools I'm interested in:
UNC, UC San Fran, UL Chicago, USC, Pittsburgh, U of Washington, Wisconsin, UC Denver, UC San Diego, Northeastern
Use the search engine on the SDN portal and type in "Supplemental Application Questions" and see what you get.
Off the top of my head I would say no threads exist or its been a long while. This is mostly due to most applications asking the same / very similar questions. For the majority of programs, it's better to state them as "secondary applications" since PharmCAS for 90% of schools is considered the primary app that includes both PCAT and transcripts submitted with calculated GPAs.
