A Note on Year 11:
If I had one thing to say to someone going into year 11 this year it’s that this is the time to start working hard. Not only are year 11 concepts crucial to year 12, but often the content is similarly difficult. That does have one big benefit though, if you find yourself struggling now, don’t stress; it will only get easier as you build understanding and study techniques, especially if you work closely with your teacher or a KIS Tutor.
Module 1: Properties and Structure of Matter
Key Concepts:
- Elements, compounds, and mixtures.
- Atomic structure, isotopes, and electron configurations.
- Periodic table trends and bonding types (ionic, covalent, metallic).
Tips for Success: Focus on understanding atomic structure and how it influences properties. Work hard to find an intuitive understanding of periodic trends as it will build the basis of why it all works.
Module 2: Introduction to Quantitative Chemistry
Key Concepts:
- The mole concept and stoichiometry.
- Balancing chemical equations.
- Concentration calculations and gas laws.
Tips for Success: This is your first introduction to calculations in chemistry so try to be neat and show all your working. The biggest marks lost are often the silly mistakes so be careful!
Module 3: Reactive Chemistry
Key Concepts:
- Types of chemical reactions (e.g., synthesis, decomposition, combustion).
- Reaction rates and factors affecting them (e.g., temperature, catalysts).
- Energy changes in reactions (endothermic vs. exothermic).
Tips for Success: Pay close attention because this will be a massive component of Module 5 of the HSC course. To succeed here, I would suggest building clear, detailed notes you can keep coming back to when you get lost.
Module 4: Drivers of Reactions
Key Concepts:
- Enthalpy and entropy.
- Gibbs free energy and spontaneity.
- Redox reactions and electrochemical cells.
Tips for Success: Learn the relationship between enthalpy, entropy, and Gibbs free energy to predict reaction spontaneity. For redox reactions, practice writing half-equations and balancing redox equations. Use diagrams to explain how electrochemical cells work.
Understanding the HSC Modules:
Year 12 HSC Chemistry is divided into four modules, each exploring different aspects of chemistry. The key to success is not only perfecting an understanding of each module but also being able to synthesise information across the whole subject and package it into a single answer.
Module 5: Equilibrium and Acid Reactions
Key Concepts:
- Static and dynamic equilibrium in chemical systems.
- Factors that affect equilibrium (Le Chatelier’s Principle).
- pH, indicators, and the properties of acids and bases.
- Calculations involving equilibrium constants (Keq) and solubility products (Ksp).
Tips For Success: Focus on predicting the marking criteria and tailoring responses to the exact wording of the question, you’ll find it much easier to earn maximum marks—practice will help you identify what works.

Module 6: Acid/Base Reactions
Key Concepts:
- Bronsted-Lowry theory of acids and bases.
- Acid-base titrations and calculations (e.g., finding concentrations).
- Buffers and their role in maintaining pH.
- Indicators and their use in titrations.
Tips for Success: For titration calculation questions, always include a balanced equation, clear steps, and correct units - it’s very easy to get lost with so much going on. Practice setting out your working logically, as messy calculations can cost marks.

Module 7: Organic Chemistry
Key Concepts:
- Nomenclature and functional groups (e.g., alkanes, alkenes, alcohols, carboxylic acids).
- Reaction pathways and mechanisms (e.g., substitution, addition, oxidation).
- Polymers and their synthesis.
Tips for Success: Having a very neat set of notes is super important for this section, and everything is easier with a set of flowcharts and tables to explain it all. Create flowcharts to map out reaction pathways (e.g., how alkanes become alkenes, then alcohols, then carboxylic acids). This visual approach helps you see the connections between reactions.

Module 8: Applying Chemical Ideas
Key Concepts:
- Analysis of inorganic substances (e.g., gravimetric analysis, colourimetry).
- Chemical synthesis and design (e.g., green chemistry principles).
- The role of chemistry in society (e.g., pharmaceuticals, environmental management).
- Interpretation of data from analytical techniques (e.g., NMR, chromatography).
Tips for Success: Be prepared to pool everything you have learnt in the other modules, as this module is all about practical application. Questions often ask you to identify substances or explain trends, so get comfortable with reading and interpreting a variety of data sets. This kind of thing only comes with practice so don’t stop doing practice questions.

3 Key Takeaways For Exams
- Practice Past Papers: Simulate exam conditions to improve time management and identify weak areas.
- Tailor Responses to Marking Criteria: Predict what examiners want and write to meet those points exactly, don’t waste time showing off!
- Stay Calm and Logical: In the exam, read questions carefully, plan your answers, and manage your time effectively. If you are methodical about your approach you will have plenty of time to finish, so don't stress!
These skills may seem hard to master, but with the right Chemistry Tutor, you can be ready to ace it in no time.

FAQs
What’s the hardest module in the HSC?
Personally I found Module 7 the most challenging because of the sheer amount of content in it, and that it was conceptually quite different to modules 5 and 6. However, with clear planning and organisation, it shouldn’t be too challenging - every person is different!
How important is the syllabus?
The syllabus is your bible—every exam question is based on it. Use it to structure your study plan and ensure you’ve covered every dot point. Pay special attention to verbs like “explain,” “calculate,” and “evaluate,” as they indicate the depth of response required.
What are the most common mistakes made in exams?
Not reading the question properly. So many times I thought I had seen a question before and just jumped straight in only to realise I had forgotten the main part of the question. Make sure to highlight the keywords and plan your responses before starting.
