There's also a set of independant papers (not CSSA) that are used by some schools, but I'm not sure which schools use then, if they are actually what I think they are.Triangulum said:They're internal assessments set by the school. However, a lot of schools, both Catholic and otherwise, use the Catholic Secondary Schools Association (CSSA) trials, which are the same format as the HSC exam and are done to a fixed timetable across the state.
