There are also some schools who do use PharmCAS that don't look at the PCAT score regardless (california schools come to mind). However, even if they say they don't consider it, if someone is looking over your pharmcas application and happens to see a sub-par PCAT score, it is highly likely that it will subconsciously be taken into account when you're being compared with the 30 other people with similar GPA and ECs and just happen not to have a glaringly weak PCAT.
Your best bet is just to shore up your weak points the best you can so that they are at least in the average pool.
