The data relating to each of your HSC courses shows all values used by the Board of Studies in the processing of your results, from initial input data (ie school assessment marks and raw marks for each examination question) to your final reported results.
It is presented in an approximately chronological order of processing, rather than in the order specified in your FOI request. Also, for clarity, some data presented is additional to that requested by you. This data is where there are additional steps in the processing of the data, such as optional question scaling (where students may choose from a range of options in an examination) and common paper equating in English (Advanced), or for completeness.
