FAQ

Frequently Asked

Everything you need to know before you start. Tap any question to reveal the answer.

Why do I study but forget everything in the exam?
Because re-reading notes feels like learning but barely sticks. Your brain keeps what it has to actively pull back out — so you remember more by testing yourself than by reviewing. Study Decoder is built around that: here's the full breakdown of why you forget, or jump straight into conversational flashcards and practice questions that make it stick.
How do I actually remember what I study for the HSC?
Three things, on repeat: active recall (test yourself instead of re-reading), spaced repetition (review just before you'd forget), and real exam-style questions under pressure. Full routine here — or let our spaced-repetition flashcards and free HSC practice questions handle the schedule for you.
How is this different to ChatGPT?
ChatGPT isn't trained on the syllabus. Our bots are trained directly on the official NESA documents — and they're fully interactive, so you can chat, follow up, and dig deeper into any topic.
Which subjects do you support?
All 45 NSW HSC (Stage 6) subjects across English, Maths, Sciences, HSIE, Creative Arts, TAS, PDHPE and VET — plus Years 7–10 English, Maths and Science for junior students.
Is there a free version?
Yes. You can try every tool for free with daily limits. Upgrade only if you want unlimited use, longer chats and full access to PDF exports.
Will the answers actually match what NESA wants?
Our bots reference the syllabus dot-points, glossary and marking guidance directly. Practice questions are styled like real HSC items, and feedback is mapped to the criteria markers actually use.
Can I cancel anytime?
Yes. Subscriptions are month-to-month — cancel from your account in one click. Lifetime access is a one-off payment with no recurring charges.
Is my data private?
Your chats and uploads are tied to your account and never sold. We only use them to power the tools you're using right now — that's it.
