The hsc course is based more on the ottawa charter and the jakarta declaration. There are many science orientated aspects of the body you will learn, for eg the way atp/pc, the lactic acid system and the aerobic system assist the body in moving and how they provide energy, hardly anybody, apparently uses the long form of the chemicals.... so that is the basis of the core structure and the rest depends on the options the teacher gives....
so bottom line is it comes back to being sciencey or englishy.... if that makes sense... hope that helps
