Exam-style feedback.

Q: What Science Extension 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 Science Extension?

Yes. The Free plan is $0 forever, needs no card, and you can try a Science Extension 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 Science Extension 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 Science Extension 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: Can it help with my Scientific Research Report?

Yes. Paste a section — question, literature review, method or discussion — and it comes back marked against the report criteria, with the specific sentence that weakened the argument.

Q: Does it cover the statistics?

Yes: sampling, descriptive statistics, significance testing, confidence intervals and the interpretation traps that cost marks in the report.

The difference

Getting the answer isn't the same as learning.

A chatbot hands you a polished Science Extension 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 Science Extension syllabus.

Science Extension is not a content course — it is a research course, assessed almost entirely on a scientific research report you design and write yourself. The examinable skills are framing a research question, justifying a methodology, handling statistics honestly and writing to the conventions of a scientific paper.

HSC · NESAModules 1–4, taken alongside another Science course. The assessment is dominated by the Scientific Research Report, with the externally assessed component built on the same research skills.

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 Science Extension marks are actually earned.

Pick a topic

Choose one of the Science Extension 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 Science Extension: the answer, the criteria it meets, and the detail it needs next.

Where the marks usually go: The most common fault in this course is treating a significant p-value as a large or meaningful effect — they are separate claims and each needs its own evidence.

Question 1 of 5 Standard Written 6 marks

A student reports that their treatment group had a higher mean growth rate than the control (p = 0.04) and concludes that the treatment causes faster growth. Assess this conclusion.

Your answer

The result is statistically significant because p is less than 0.05, so the difference is unlikely to be due to chance. However, the student cannot really say it causes faster growth because there might be other factors involved.

Three mistakes that cost Science Extension marks every year

01
A research question too broad to answer. “How does pollution affect fish?” has no measurable variable, no population and no scope, and everything downstream inherits the fault.
02
Summarising the literature instead of arguing with it. A review has to establish the gap the project fills, not list what other people found.
03
Reporting a p-value as proof. Significance is a statement about the probability of the data under the null hypothesis, not about the size or importance of the effect.
