I listed on my Pharmcas application that I was planning on taking the PCAT again. I got a few interview offers with my first PCAT score but UF put my application on hold until I received the new score. After the new score came in around March, I got accepted to UF.
So if the schools like your first score or two, they'll go ahead and call you up for an interview... otherwise the majority will wait until the new score comes in, so long as you met all of their other requirements.
