You mean BRS Pathology? Well, BRS Path and Pathophys for boards and wards are slightly different. BRS path is purely pathology but the other book also incorporates some phys,pathophys, and perhaps a few treatments too. If you are studying path, go with BRS. The 2 books take different approaches. Just by itself, the pathophys for boards and wards is probably not sufficient at all for path exams but BRS path is.
