ABOUT THE AUTHOR:
Hi, I’m Mao! I’m the author and producer of Peak Academics, a guide
designed to help students achieve their best results. I graduated in
2023 with an ATAR of 99.25, and I created this guide using the exact
study strategies that helped me reach that score. During Year 12, I
studied Chemistry alongside Specialist Mathematics and Physics, and
I believe in studying smart, not hard. In this guide, I’ll share everything
that worked for me to help you succeed.

QCE CHEMISTRY SYLLABUS
Overview of Units 1–4
The course is structured into four units, each focusing on different
areas of chemistry, which build on each other as you progress through
the two-year course.
Unit 1: Chemical Fundamentals
Unit 1 is all about laying the foundation of chemistry. You’ll start by
exploring the structure of atoms, understanding their components and
how they form different substances. Chemical reactions and their
energy changes will also be introduced.
Key Topics:
Structure of Atoms: Understand the atomic number, mass
number, protons, neutrons, and electrons. Learn about isotopes
and their significance.
States of Matter: Learn the properties of solids, liquids, and gases
and how they transition between states.
Chemical Reactions:
Types of reactions (e.g., synthesis, decomposition,
combustion).
Energy changes in reactions (exothermic vs. endothermic).
Conservation of mass.
Energy in Chemical Reactions: Focus on the role of energy in
breaking and forming bonds, and how reactions either release or
absorb energy.
