The function of a top-tier prelim is to inoculate students against examination shock.

Consequently, students who performed moderately well on this prelim often found the actual A-Level paper relatively manageable. Thus, the 2012 paper functioned as an effective training tool, raising the bar so that the official bar seemed lower by comparison. Indeed, historical data suggests that the national mean
