Does your P4 grade in PowerSchool show up in your final report card? Does a P grade on PowerSchool count towards your GPA?
This is probably school dependent so take it with a grain of salt, but P4 stands for period 4 so if that’s a normal class then probably. If its lunch or something probably not. A P grade means passing and shouldn’t be calculated into the GPA.
You should probably ask the administration since no one is familiar with your school system.
