HSC Chemistry is structured as a Year 11 Preliminary course followed by the Year 12 HSC course, where final external assessments are completed.

Topics are aligned with the HSC exam structure and can be used directly for targeted practice.

Year 12 (HSC) topics contribute to the final ATAR and focus on exam-level applications and analysis.

Chemistry is a single HSC science subject, so the table shows year-based topics rather than Units 1–4 or Areas of Study.

This page focuses on NSW senior Chemistry topics so conceptual, calculation, diagram, and analysis requirements can be compared clearly across Year 11 and Year 12.
