How do I find what Prereqs to take

Hello OT community, My SO is very interested in becoming an OT. I'm applying to PT school and I know we have PTCAS where you can easily reference the prerequisite courses and average accepted GPAs for most schools. Is there a similar link for OT prereqs and GPAs? If not, what do most of them look for for prereqs and GPAs? Thanks!
