The short answer
Your HSC mark in each course is half school assessment and half HSC exam, and it is reported as a band, with Band 6 starting at 90. Your ATAR is a separate rank that UAC builds from scaled marks in your best 10 units, including 2 units of English. So study for both halves all year, and practise with past papers under exam conditions.
How your HSC mark is made
Every HSC course gives you three numbers: an assessment mark from your school, an exam mark from the HSC exam, and an HSC mark, which is the average of the two.[2] NESA puts it plainly: your mark is a 50:50 combination of the exam and your school-based assessment.[1]
Your school assessment marks are moderated before they count. NESA uses your school group's HSC exam marks for that course as anchor points, so marks from different schools can be compared fairly.[3] Each student's rank stays the same when school assessments are moderated.[3] Your place in the order is yours to earn, and the group's exam results set the scale.
| Band | HSC mark (2-unit courses) |
|---|---|
| Band 6 | 90 to 100[1] |
| Band 5 | 80 to 89[1] |
| Band 4 | 70 to 79[1] |
| Band 3 | 60 to 69[1] |
| Band 2 | 50 to 59[1] |
| Band 1 | 0 to 49[1] |
Extension courses use their own bands, E4 (highest) to E1.[1] Because exam papers change every year, expert judges set where each band starts on that year's paper, and those raw cut-offs are not published.[2]
What the 50:50 split means for how you study
- Assessment tasks are half of every course, so treat each one like an exam. A task early in the year counts towards the same HSC mark as the final exam.
- Moderation keeps your rank within your school, so where you finish relative to your classmates on internal tasks carries straight through.[3]
- Your school group's exam results set the scale for everyone's assessment marks,[3] so the exam still matters for students who did well in their assessments.
The study habits that suit a year-long, two-part mark are the ones with the strongest evidence. Spreading revision over weeks beats cramming the same hours into a few days.[8] Testing yourself beats rereading and highlighting, which a major review rated as low-utility.[7][9] Start with active recall and spaced repetition, and use them from Term 1, not just in trial-exam season.
Past papers and marking guidelines
NESA publishes past HSC exam papers alongside their marking guidelines.[6] The guidelines show what earns marks at each level, which is the clearest picture you will get of what the markers want.
- Pick a recent paper and do it timed, closed book.
- Mark it yourself against the marking guidelines, not against your notes.
- List every lost mark and why you lost it: did you not know it, misread the question, or run out of time?
- A week later, redo the questions you lost marks on without looking at the answers.
For essay subjects, plan every practice answer to the guideline's top band first. How to write better essays walks through that.
How your HSC results become an ATAR
Your ATAR is not your HSC marks. It is a rank against your whole age group, which UAC calculates from an aggregate of scaled marks in 10 units: your best 2 units of English and your best 8 units from everything else.[5]
UAC uses your scaled marks, not your HSC marks, and for most courses the scaled mark is lower than the HSC mark.[5] Scaled marks are not reported to students.[5] The stated principle is that you should be neither advantaged nor disadvantaged by choosing one pattern of study over another.[5] In practice that means choosing subjects you can do well in beats chasing the ones you have heard scale well.
Because 2 units of English always go into the calculation, English is the one subject you cannot leave out of your plan.
The other HSC rules to know
- Your Year 11 (Preliminary) pattern of study needs at least 12 units and your HSC pattern at least 10. Each must include 6 units of Board Developed courses, 2 units of English, 3 courses of 2 or more units, and 4 subjects.[4]
- You have to meet the HSC minimum standard of literacy and numeracy, which means reaching Level 3 or 4 in short online reading, writing and numeracy tests.[10] You have 5 years from starting your HSC courses to meet it.[4]
- English Studies counts towards your ATAR only if you sit its optional HSC exam.[4]
