This is not really how it works - look up the moderation process which matches the school 'end of year' marks to the HSC standard. Simply put, NESA take the cohort's HSC marks and shoves them onto the school's 'end of year' marks. This is to make things fair between schools. Some people think that their marks being worse in the HSC than at school is "being scaled down" - this is a function of their school teachers marking too easy/exams too easy and them not being as well prepared for the HSC.
| School 1 | | | School 2 | | |
| HSC Exam mark | 'end of year mark' | HSC 'internal' | HSC Exam mark | 'end of year mark' | HSC 'internal' |
Student 1 | 72 | 42 | 72 | 72 | 93 | 72 |
Student 2 | 76 | 48 | 76 | 76 | 95 | 76 |
Student 3 | 80 | 54 | 80 | 80 | 97 | 80 |
Student 4 | 84 | 60 | 84 | 84 | 99 | 84 |
As you can see, the exact marks your teachers give you in school have no bearing on your HSC internal mark - rather it is your rank and relative spaces between students. School 1 marked really harsh or had really hard exams and School 2 marked more leniently but they all ended up with the same HSC marks.
A little bit of shuffling happens if your ranks don't perfectly line up which is why people emphasise the importance of ranking.
Generally with my experience of English (standard in particular), the marking is quite subjective but within a school there should be some sort of consistency so nobody is really unfairly dis/advantaged. However, when it gets to the HSC, regarding standard vs advanced, the alignment process (turning the raw mark you scored in the HSC to a mark in one of the 6 bands) makes it a lot rarer for a student to get a band 6 in standard.
