ACPTWannabe is correct. I asked the same thing months ago. At that time, I did not realizes PTCAS had a tab for all the schools, listing each schools pre-reqs. So I keyed in my entire transcript into Excel. Then I put a column beside each to put an 'X' in. Then wrote a formula to calculate the GPA of the classes X'd. This allowed me to run through fairly quickly, marking each schools pre-req, get a pGPA, then clear the X's and run through another. Since I was considering many schools, this ended up saving a lot of time as I considered pGPA's.
