Q: What Chemistry topics does ATARprepAI cover?

Anything on your syllabus. Every topic and every syllabus point listed on this page starts a quiz on that point alone, and the topic box takes whatever else you type — including a dot point copied straight out of the study design.

Q: Is ATARprepAI free for Chemistry?

Yes. The Free plan is $0 forever, needs no card, and you can try a Chemistry quiz without even making an account. Free accounts get a monthly allowance of freshly generated quizzes; the current numbers are on the pricing page.

Q: Do I need an account to start?

No. You can generate and play a Chemistry quiz signed out. An account adds saved progress across devices, streaks, and a bank of the questions you got wrong.

Q: Which exam boards does it follow?

WACE, VCE, HSC, QCE and SACE. Pick yours and the Chemistry questions use that board's command words and paper structure rather than a generic global syllabus.

Q: Are the questions actually marked, or just answered?

Marked. You attempt the question first, then it comes back scored against the criteria — with the specific line that lost the mark and what would have earned it.

Q: Is this just ChatGPT with a different logo?

No. A chatbot hands you a finished answer. This makes you attempt the question yourself, then marks your work against the exam criteria.

Q: Will the calculation questions show full working?

Yes. Worked solutions set out the balanced equation, the mole ratio, the substitution and the final answer with units, so you can see which line of your own working went wrong.

Q: Does it cover organic reaction pathways?

Yes — substitution, addition, esterification, oxidation and polymerisation, including multi-step pathway questions that ask you to name the reagents and conditions at each arrow.

The difference

Getting the answer isn't the same as learning.

A chatbot hands you a polished Chemistry answer. An examiner hands you marks. ATARprepAI closes that gap — you attempt the question, it marks your work, and you find out what to fix.

What you're actually tested on

What's on the Chemistry syllabus.

Chemistry is the ATAR science where the working is worth more than the answer. Calculation questions award method marks for the balanced equation, the mole ratio and the units, so a correct number with no working still loses most of them. The written questions are the mirror image: they want a reason in the language of collisions, energy and equilibrium.

HSC · NESAYear 11 Modules 1–4 (Properties and Structure of Matter, Introduction to Quantitative Chemistry, Reactive Chemistry, Drivers of Reactions), then Year 12 Modules 5–8 (Equilibrium and Acid Reactions, Acid/Base Reactions, Organic Chemistry, Applying Chemical Ideas).
VCE · VCAAUnits 1–4. Unit 3 covers chemical energy and how it is measured and Unit 4 the chemistry of carbon-based molecules, with a student-designed investigation assessed across Units 3 and 4.
WACE · SCSAUnits 1 and 2 in Year 11, Units 3 and 4 in Year 12. The SCSA examination is half the ATAR mark and is dominated by multi-step calculations with method marks.
QCE · QCAAUnits 1–4 with a data test, a student experiment and a research investigation, plus a 50 per cent external examination.
SACE BoardStage 2 is 70 per cent school assessment, including an investigations folio, and a 30 per cent external examination.

Boards revise their syllabuses — check yours for the current wording. Every point above is a live topic in the quiz builder: tap one to be tested on it.

How it works

Practise the way Chemistry marks are actually earned.

Pick a topic

Choose one of the Chemistry topics above or type your own, then pick your state. WACE, VCE, HSC, QCE and SACE each word their questions differently, and the paper follows yours.

Attempt it yourself

Exam-style questions with the mark allocation showing, so you know how much to write. You answer them — nothing is handed to you.

Get it marked

Your answer comes back marked criterion by criterion in seconds — what you earned, what you half-earned, and what the examiner never saw.

Fix the gap

Rewrite your answer with the feedback beside it, or take a fresh question on the same point, and the topics you keep losing marks on come back around in review.

A worked marking example

See where the marks come from.

An example from Chemistry: the answer, the criteria it meets, and the detail it needs next.

Where the marks usually go: Students name the Le Chatelier shift but never say what happens to K, or treat a faster rate as if it meant a higher yield.

Question 1 of 5 Standard Written 6 marks

In the Haber process, N₂(g) + 3H₂(g) ⇌ 2NH₃(g) is exothermic in the forward direction. Explain the effect of raising the temperature on the ammonia yield, on the equilibrium constant K, and on the rate of reaction.

Your answer

Increasing the temperature favours the endothermic reverse reaction, since the forward reaction is exothermic, so the equilibrium shifts left and the yield of ammonia decreases. The rate still increases because the particles move faster and collide more frequently, so equilibrium is reached sooner.

Three mistakes that cost Chemistry marks every year

01
Skipping the balanced equation. Mole-ratio marks are awarded from it, so an unbalanced or missing equation costs marks the correct final answer cannot win back.
02
Dropping units and significant figures. Most boards award a dedicated mark for both, and it is the single most commonly forfeited mark in the paper.
03
Answering an equilibrium question with “the equilibrium shifts right” and stopping. The mark scheme wants the effect on yield, on rate and on K stated separately.
