HSC Maths Standard 2: the 100 mark exam for 2027, the Year 12 topics and how to practise

The HSC Maths Standard 2 exam

Checked against the NESA syllabus pages on 11 November 2026. The new Mathematics Standard 11 to 12 Syllabus (2024) started in Year 12 in Term 4 2026, and 2027 is the first HSC exam for it.

The exam focuses on Year 12 outcomes, but the Year 11 Standard course is assumed knowledge and may be examined. The 2027 HSC written exams run from Wednesday 13 October to no later than Friday 5 November 2027, and NESA releases the timetable on Friday 30 April 2027. Mathematics Standard 1 has an optional exam; Standard 2 is the one with a compulsory HSC exam and it can count toward your ATAR through the Universities Admissions Centre.

The Year 12 areas of study

Year 11 sets the groundwork in formulas and equations, linear relationships, earning and managing money, measurement and time and location, networks, paths and trees, and data analysis. Each year is 120 hours.

How the mark and bands work

Your course mark is a 50:50 combination of your HSC exam mark and your school-based assessment mark. In a 2 unit course Band 6 is 90 to 100, Band 5 is 80 to 89, Band 4 is 70 to 79, Band 3 is 60 to 69, Band 2 is 50 to 59 and Band 1 is 0 to 49. Your school sets its tasks, normally weighing 10% to 40% each, with at most one take-home task worth up to 15%. The UAC calculates the ATAR from moderated assessment marks and exam marks.

Worked examples

Annuities

You save $500 at the end of every quarter for 3 years at 4% per annum compounded quarterly. That is 12 payments at 1% per period, so the future value is:

The $6000 you paid in has earned about $341 of interest. Check your reference sheet before the exam to see how the annuity formula is given, and write the number of periods and the rate per period first.

Network flow

In a pipe network, the maximum flow from source to sink equals the capacity of the minimum cut. Find it by drawing a line that separates the source from the sink and adding the capacities of the arcs that cross it in the direction of flow. The smallest such sum is the answer, so test every cut you can see, not only the first.

The normal distribution

Test scores are approximately normal with mean 72 and standard deviation 8. A score of 88 is two standard deviations above the mean, so its z-score is (88 − 72) ÷ 8 = 2. About 95% of scores lie within two standard deviations, so about 2.5% score above 88.

Try a normal distribution question from the Probability course, then press Mark:

Using the daily paper as a trial

Each daily paper has 8 original questions and 25 to 35 marks, a short timed trial of 35 to 45 minutes, not a full Standard 2 paper. For school trials and their dates, see our HSC trials guide, and for the other courses the HSC Maths guide.

The Year 12 Statistics paper fits the statistics area: the normal distribution, correlation and regression, data presentation, measures of location and spread, and probability questions. Skip hypothesis testing, the binomial distribution and sampling, which are not in Standard 2. Annuities, networks and trigonometry are not on this paper, so practise them from your own notes or past HSC papers on the NESA site.

Exam answers

Answers and a worked mark scheme for the daily paper come with today's paper once it's marked. They are ours: NESA publishes its own marking guidelines after each HSC.

Common mistakes in HSC Maths Standard 2

• Using the annual rate per period. Divide the annual rate by the number of periods in the year, and count the payments.
• Stopping at the first cut in a network. The minimum cut is the smallest of all of them.
• Not interpreting a correlation. A strong correlation does not show one variable causes the other.
• Rounding too early. Keep full calculator values until the last step.
