The HSC is pretty complicated as it stands, and we've done our best to explain it in prior blog posts.

If you've read our "How the HSC works: Understanding New South Wales' Year 12 ATAR System" article, you might recall that there are quite a few options when it comes to your subjects for English, Maths and Science.

Let's take a look!


2 units of English is compulsory and will count towards your ATAR. In year 11 for most students their choices are (listed by increasing difficulty):

  • Standard English (2 units)
  • English Advanced (2 units)
  • English Advanced and English Extension 1 (3 units)

There are also EAL courses and English studies, but these are uncommon choices. The biggest difference between Standard and Advanced is that in Advanced you have to do a Shakespeare text. English advanced and extension syllabuses changed in 2019.

In year 12 students taking advanced and extension 1 can choose to pick up extension 2 as well. This is a major work where the students write a narrative (there is no exam component).

For both Standard and Advanced there are 4 modules, including a “common module” which both Standard and Advanced do. The 4 Modules are:

For advanced across all the modules you study 4 texts (1 in common, 2 in A and 1 in B). There must be at least one:

  • Shakespearean drama
  • Prose fiction
  • Poetry or drama

Mod C is completely separate from this. You also have to study a related text (of your choosing) in the common mod.

For standard it is the same but instead of Shakespeare they have a digital text.

For Extension 1 there are only 2 modules (as it is only one unit, it is half the work). There is the common module called “Literary Worlds” and then a choice of elective module. The choices are:

  1. Literary Homelands
  2. Worlds of Upheaval
  3. Reimagined worlds
  4. Literary Mindscapes
  5. Intersecting worlds

For each elective students study at least 3 prescribed texts as well as 2 related texts of their choosing (yes, all for one module).

The exam is a 25-mark common module response (critical or creative or both) and a 25-mark essay on the chosen elective.


Maths is optional, but obviously lots of students take it. In year 11 for most students their choices are (listed by increasing difficulty):

  • Standard 2 (2 units)
  • Advanced (2 units)
  • Advanced and Extension 1 (3 units)

There is also standard 1 but few schools offer this. The main difference between standard and advanced is that advanced is a calculus course and standard is not. The standard syllabus changed in 2019, the advanced and extension syllabuses changed in 2020.

In year 12 students taking advanced and extension 1 can choose to pick up extension 2 (1 unit) as well. This is a very challenging course. In contrast to English, if you choose to do extension 2 maths you do NOT sit the advanced exam. Technically, you are enrolled in advanced (therefore doing 4 units of maths) but by the time you get to the HSC you take the 2-hour Extension 1 exam and the 3-hour Extension 2 exam only. This means your extension 1 and 2 marks (each out of 50) get doubled to make up your 4 units worth of marks.

The year 12 topics covered are:


In year 11 science choices include:

  • Biology (2 units)
  • Chemistry (2 units)
  • Psychics (2 units)
  • Earth and Environmental (2 units)
  • Investigating Science (2 units)

In year 11 you can choose MAX 6 units of science courses.

In year 12 you can pick up:

  • Investigating science (2 units)*
  • Science extension (1 unit)**
  • Year 11 investigating science is not a prerequisite for this course. It is an easier course which some choose to replace their year 11 science with, in year 12.
  • *Science Extension is a course with a focus on the authentic application of scientific research skills to produce a Scientific Research Report generally acceptable for publication.

In year 12 you can choose MAX 7 units of science courses.

For every science course there is a depth study requirement. A depth study is an investigation/activity that allows the further development of one or more concepts found within or inspired by the syllabus. Normally this is an experiment / series of experiments where you “find out” things. Your teacher isn’t supposed to help you. For example, my year 12 chemistry depth study was a series of acid/base titrations.

Science labels their year 12 modules as 5, 6, 7 & 8 (continuing from the 4 year 11 modules) and they are:

In Conclusion...

The HSC system can be quite complex, and understanding what's going on can be very daunting for new students and parents.
