Click on Schools Online to log into the 2011 Higher School Certificate Components Report for each school.This report indicates how consistently each individual student has performed across different components of the examination. The figures do not indicate the performance of an individual student relative to other students, but the student's performance in each component relative to his/her performance in other components. 

The following animations represent molecular-level models of three classifications of pure substance based on the chemical bonding involved - metallic (e.g. solid copper), ionic (e.g. solid sodium chloride), and intermolecular (e.g. liquid water, liquid oxygen). Animations comparing substances in different states, and undergoing changes of state, are also listed so that the differences in intraparticle and and interparticle bonding can be discussed. This topic is known for the student misconceptions and confusion it can cause without careful visualisation. Temperature is correlated with the degree of particle movement.
