What PrepHSC is

PrepHSC is HSC practice. Your child answers questions, gets a mark, and sees the skill behind each mark they lose, then gets the next question that works on that skill.

Physics (Modules 5 to 8) is open now. Chemistry, Biology, Maths Standard 2, Maths Advanced, Maths Extension 1, Maths Extension 2 and Ancient History open at launch in March 2027.

It is practice, not a tutor and not the real HSC. Marks are not official HSC results, and we do not promise any HSC result.

PrepHSC is not affiliated with or endorsed by NESA.

How answers are marked

• Multiple choice answers are checked automatically.
• Written answers are marked by AI, not by a teacher, against each question's own criteria. A second pass checks the first, and the numbers in a calculation are checked by code.
• Answers the AI cannot mark safely go to a person on our team.
• AI marking can be wrong. If your child thinks a mark on a written answer is wrong, they can flag it once, and a person checks it. The mark can go up, go down or stay the same.

How marking works

What it costs

• Free: multiple choice questions every day. No card needed.
• Every written answer costs real money to mark, so limits on how many can be sent apply on every plan. The Terms list them.
• Prices are in Australian dollars. Stripe collects card details. We never see them.

Pricing

Renewing and cancelling

Pro renews automatically, every month or every year, until it is cancelled.

It can be cancelled online at any time from the Account page, which opens Stripe's billing portal. Pro stays on until the end of the month or year paid for, with no further charge, then the account moves to Free. Cancelling does not refund the time left, but your rights under the Australian Consumer Law still apply.

Age, and your agreement

Students must be 13 or over.

If your child is under 18, a parent or guardian must know they are signing up, and must agree to the Terms before they buy Pro. At sign-up, they tick a box to say they are 18 or over, or that a parent or guardian knows they are signing up.

We do not ask students how old they are. We rely on what they tell us at sign-up. We do not check their age or contact you.

What you can see

Parents and guardians do not get a login or a view of a student's account. Your child sees their own answers, marks and weak areas when they sign in.

If you have a question, email us at support@prephsc.com.au.

Your child's data

• Accounts, answers, photos, marks and weak areas are stored with Supabase in Sydney, Australia.
• Written answers and photos are sent to Anthropic, our AI provider, in the United States, to be marked. We do not add your child's name or email, but anything written on the page goes with it.
• We do not sell data, we do not show ads, and we do not train AI models on student answers.
• We use cookies only to keep students signed in and remember their dark mode choice. No advertising or analytics cookies.
• Your child can delete their account from the Account page at any time.
