 These two tests have more similar sample groups to the CSAT than private mock tests do.Moreover, the PCSAT's examiner committee is similar to that of the CSAT, so the types of questions resemble those seen in the CSAT.In particular, since the CSAT Simulation is hosted by the same institution as the CSAT, it is being used to predict the level of difficulty or the types of questions that might appear in the same year's CSAT.
