its pretty complex
basically
they group all yoru schools internal assessment marks For a subject(lets call that G)
then they get your internal assessment mark for that subject (lets call it X)
and they put X/G
which will give u a percentage of your internal assessment over the total group for that subject (lets call that P)
so X/G = P
now,
oncce the subject is done externally
they get all the external marks from your cohort and add them together (lets call that A)
then they get your internal percentage (P) and they put
P multiplied by A
as your internal moderated assessment mark
so the percentage of your itnernal mark of the total internal marks multiplied by the total external marks gives u your moderated internal mark
then they get that, add it to your actual external exam mark, divide it by 2
and bobs your uncle
your aligned hsc mark
whcih then gets sent to uai centre where it gets eviscerated
