Competition Preparation

RACI Australian Chemistry Quiz Preparation

To prepare for the RACI Chemistry Quiz, revise core chemistry language and representations, practise explaining why reactions and trends happen, and work past papers under the 60-minute, 30-question pace — the quiz rewards applied reasoning in context rather than isolated recall. Run by the Royal Australian Chemical Institute, the International Chemistry Quiz (formerly the Australian National Chemistry Quiz) is one of the most widely sat chemistry competitions in the world and an accessible, engaging entry into chemistry beyond the classroom.

Key facts at a glance

What the quiz tests

The RACI Chemistry Quiz presents chemistry in real and unfamiliar contexts and asks students to reason from it. Rather than reciting definitions, students interpret information — a reaction, a trend, a piece of data — and apply chemistry to explain or predict. The three signals the organisers themselves highlight are revising core chemistry language and representations, being able to explain why a reaction or trend happens, and connecting chemistry practice to broader science data questions.

Content by level

Because there are four tiers, each student meets chemistry pitched to their stage. A rough guide to the emphasis at each level:

LevelTypical emphasis
Years 7-8States of matter, mixtures, basic reactions, particle ideas, reading chemical information
Years 9-10Atomic structure, the periodic table, bonding, reaction types, simple stoichiometry
Year 11Quantitative chemistry, bonding and structure, reactions and energy in more depth
Year 12Equilibrium, acids and bases, organic and applied chemistry at senior depth

A practical preparation plan

  1. Secure the language. Make sure chemical symbols, equations and representations are second nature for the level — misreading notation costs easy marks.
  2. Practise ‘why’ questions. For each fact, rehearse the reason behind it; the quiz rewards explanation over recall.
  3. Work in context. Use questions set in real situations and data, since that is the quiz’s style.
  4. Time it. 30 questions in 60 minutes is a comfortable pace, but practising it removes any clock anxiety.
  5. Review past papers by type. RACI publishes past papers; sort misses into ‘didn’t know’ and ‘misread’ and target the pattern.

Common mistakes to avoid

Because the quiz is multiple-choice and time-limited, the marks students lose most often are not about deep chemistry — they are avoidable. The first is misreading the chemistry notation: confusing a subscript with a coefficient, or a charge with an oxidation number, turns a known answer into a wrong one. The second is over-thinking the early questions, which are usually meant to be quick, and then rushing the harder ones at the end. The third is treating the quiz as pure recall and freezing when a question is set in an unfamiliar context. Practising on past papers fixes all three, because students learn the question style, the sensible pace, and the habit of reading a context calmly and extracting the chemistry it is actually testing. A short, honest review after each practice paper — one line per mistake naming its cause — turns those papers into the most efficient preparation available.

Where the quiz fits

The RACI Chemistry Quiz is an excellent, low-pressure way to test and grow a student’s interest in chemistry, and a natural complement to school study. For students who enjoy it and want more depth, the next step is the Australian Science Olympiad Chemistry exam, a far more demanding senior competition. See our ASOE Chemistry preparation guide for that pathway, and build foundations with the Ace Achievers Chemistry Acceleration course or the Chemistry Olympiad course. A free diagnostic can show whether a student is ready to push further.

Frequently asked questions

How do I prepare for the RACI Chemistry Quiz?

Revise core chemistry language and representations, practise explaining why reactions and trends happen, and connect chemistry to broader data questions. Work through past quiz papers under the 60-minute pace. The quiz rewards applied reasoning, not isolated recall.

What is the format of the RACI Chemistry Quiz?

The International Chemistry Quiz consists of 30 multiple-choice questions to be answered in 60 minutes, sat either on paper or online. There are four levels: Years 7-8, Years 9-10, Year 11 and Year 12.

When is the RACI Chemistry Quiz in 2026?

The 2026 quiz window is 3–7 August 2026, with registrations closing 17 July 2026. Entry is through your school, so confirm the exact sitting day and deadline with the school.

What topics does the RACI Chemistry Quiz cover?

It covers chemical reactions, bonding and conservation, the interpretation of chemistry information in context, and applied reasoning across the chemistry content for the student's level rather than rote facts.

Is the RACI Chemistry Quiz the same as the old Australian Chemistry Quiz?

Yes. The International Chemistry Quiz (ICQ) is the renamed competition formerly known as the Australian National Chemistry Quiz (ANCQ), run by the Royal Australian Chemical Institute.
