There isn't a complete list anywhere, unfortunately. I had to email most of the schools that I'm interested in to find out which ones do and which ones don't. Some have the information under the FAQ or Pre-req page on their website. Otherwise, most schools do take the higher grade, at least out of the ones that I looked into.
Which schools have you found to take the higher grade? So far I have these schools :
Duke
Western
Loma Linda
University of saint Augustine
University of Mary
Arkansas state university
CSULB, UNE, Washington Univ at St. Louis, Touro Nevada, Elon, Chatham, URI, UNTHSC, RMU, Marymount.
My point was that you should probably find schools that you're interested in, and then email them, because chances are that they'll take the highest grade. The list will be insanely long if you try to find all the schools that do.
PTCAS rarely says if a school accepts higher grades, in my experience anyways. It was on the FAQs for each school's website more often, and even then, I had to ask a majority of the schools. I agree though, look on PTCAS and the school's website thoroughly before you email admissions.
