ExploreAbout this exam
Investigating Science Stage 6 (2017) is a NSW Board Developed Course in Science, offered as a 2-unit course in Year 11 (course number 11215) and Year 12 (15215). It is designed for students who want to understand how scientific knowledge is built rather than to specialise in one discipline: the Year 11 course starts from observation and moves through inference, generalisation, scientific models, and the relationship between theories and laws, while the Year 12 course asks students to run their own investigations, report findings, examine how science and technology depend on each other, test a claim scientifically, and consider the ethical, social, economic, and political influences on research. There are no prerequisites, corequisites, or eligibility requirements, and the course cannot be studied by self-tuition. Each year includes 30 hours of course time for depth studies and at least 35 hours of practical investigations, so assessment rewards hands-on work and written scientific reports as well as content knowledge. Preparation should combine the module content with regular practice at evaluating evidence, identifying assumptions behind claims, and writing structured reports; the syllabus, sample scope and sequences, sample assessment schedules, HSC exam papers, and standards materials published by NESA are the best starting points. Students may count up to six units of Science in Year 11 and seven in Year 12 toward pattern of study requirements.
What you'll study
About HSC Investigating Science preparation
What is the format of the HSC Investigating Science exam?
The public syllabus page does not state the exam's section structure, question counts, or mark allocation, so check the current NESA assessment and exam information and past HSC papers directly. The syllabus itself lists performance band descriptions, an exam equipment list, HSC exam papers, and HSC standards materials as the assessment support for this course.
How difficult is Investigating Science compared with other sciences?
The course has nil prerequisites, corequisites, and eligibility requirements, and it focuses on how evidence, models, theories, and claims are evaluated rather than on heavy mathematical preparation. Difficulty depends mostly on how well you can design fair investigations, interpret data, and write clear scientific reports, which are explicitly part of the Year 12 course.
Can I repeat or retake the course or exam?
The source material does not describe any retake, repeat, or resit policy for this course, so no such policy is stated here. Ask your school or check NESA's current rules for your situation rather than relying on assumptions.
How much time is set aside for practical work and depth studies?
Each year provides 30 hours of course time for depth studies, which may be one investigation or a series of investigations and may sit within one module or across several. Practical investigations are essential and must occupy a minimum of 35 hours of course time each year, so plan your study around both.
In what order should I study the modules?
Work through Year 11 first: Cause and Effect – Observing, then Inferences and Generalisations, Scientific Models, and Theories and Laws. The Year 12 course builds on those skills and concepts, moving through Scientific Investigations, Technologies, Fact or Fallacy?, and Science and Society. NESA publishes sample scope and sequences for both years if you want a suggested pacing.
What are the most common ways students lose marks?
The syllabus emphasises conducting your own investigations and communicating findings in scientific reports, so weak reporting and poorly justified conclusions are likely trouble spots. In the Fact or Fallacy? module you must scientifically examine a claim, which rewards careful evaluation of evidence rather than accepting plausible-sounding statements. Practise structured report writing and evidence critique regularly.
Are there any subject exclusions or prerequisites?
Prerequisites, corequisites, and eligibility are all nil. The course is excluded with Investigating Science Life Skills (course 16642) in both Year 11 and Year 12, and it cannot be studied via self-tuition. A student may count up to six units of Science in Year 11 and seven in Year 12 toward pattern of study requirements.
Is the syllabus changing, and does that affect my preparation?
NESA states that a new Investigating Science 11–12 Draft syllabus is available for consultation as part of the NSW Curriculum Reform. No effective date for a replacement syllabus is given, so prepare against the current 2017 syllabus and confirm arrangements with your teacher.
Where can I find official practice materials?
The NESA syllabus page links HSC exam papers and HSC standards materials, plus sample scope and sequences, sample assessment schedules, and a sample depth study task for Module 1. NESA also notes that sample assessment schedules and tasks are being updated to align with new ACE Rules, including a new limit on take-home assessment tasks from Term 4 2026.
