Readiness: Building Exam-ready

Q3. $5,000 is invested at 4% p.a. compounding annually. Find the balance after 3 years. (2 marks)

Your answer $5,600 let's fix this · verified answer: $5,624.32

Where the 2 marks go

Method: use compound interest: 5,000 × (1.04)3 · 1 mark
Answer: $5,624.32 · 1 mark

You used simple interest. Compounding earns interest on the interest too. Up next in your plan: two more to lock it in.

Practice only helps when you find out what you got wrong, and why.

One teacher has a whole class and can't sit with you through every question, and a private tutor isn't always within reach. RedTexta gives you the in-between: practise on exactly your weak spots, marked against the verified answer straight away, with the method taught at the point you slip, until the topic's solid.

How it works

Three steps, starting from a question you got wrong. Works right on your phone.

1

Snap what you got wrong

Doing a practice paper? Photograph a question you got stuck on and tell RedTexta what you put. It reads the printed question — your working and any marks are ignored — and pins exactly where it went sideways.

2

See the fix, make it stick

You get the worked method, plus a step when you ask for one — marked against an answer worked out in advance, so it's exact, not a chatbot's guess. Then a fresh question of the same type to lock it in.

3

Want the bigger picture? Find your level

A quick adaptive check, about 5 minutes and stop anytime, builds a plan around your gaps — so between papers you're always working the most exam-costly ones first.

Maths you can trust: it builds the skill, not shortcuts.

RedTexta works out the right answer to every question before you see it, so the answer marking is exact, never a chatbot's confident guess. And when you slip, it teaches the method and shows you a step when you ask; it doesn't just hand over the answer. The skill becomes yours.

A general AI chatbot

  • Confidently gets maths wrong, and you can't tell when
  • Just hands you the final number to copy
  • Doesn't know the HSC syllabus or how the marks are awarded
  • Leaves you stuck in the exam, where there's no chatbot

RedTexta

  • Marks your answer against a verified key, never a chatbot's guess
  • Teaches the method and reveals one step at a time, so you do the last bit
  • Built on the NSW syllabus; marks method and answer the way the HSC does
  • Builds the skill you keep for the exam room

It's built to support how your school and NESA approach AI: a tutor that teaches, not one that does the work for you, with your working staying your own. And the maths is verified, so you're never learning from a wrong answer.

Built to be good for you

Learning that earns your attention honestly, and respects how you think.

Healthy by design

It fits a spare minute and leaves you a little sharper. Nothing here is built to keep you hooked. The only reason to come back is that last time genuinely helped. Get a real win, then get on with your day.

Made for how different brains learn

Clear and low-clutter, one next step at a time, with a worked example right where you get stuck. You set how you like your feedback. Built on Universal Design for Learning: good for everyone, essential for some.

Aligned to your course, not generic worksheets

RedTexta is built on the NSW HSC Mathematics Standard 2 syllabus. Its papers look and mark like the real thing: it knows a method mark from an answer mark, weights topics the way the exam does, and shows you exactly what the markers reward.

Live now: NSW HSC Mathematics Standard 2. More subjects as their paper generators are ready; we'll only ever show you what's genuinely ready.

Built for everyone who wants the marks to climb

It doesn't just mark you; it teaches you the fix and plans what to practise next. Clear, encouraging and specific, never just "show your working".

Fresh papers when you need them

A fresh paper whenever you need more practice, and no two are the same, so there's nothing to memorise.

Accurate marking

Marked against a verified answer key, so the answer marking is exact, not a chatbot's guess.

Help the moment you're stuck

The worked solution, a step when you ask for one, and a tutor to talk it through, right there in the question.

It's on your side

It teaches, it never judges. End a session whenever you like, and everything you tried still counts.

You want to know it's helping, and that it's the right kind of help. RedTexta is built to be the responsible alternative: the kind that makes them better, not the kind that just does the work for them.

Builds skill, not shortcuts

It teaches your child the method and gives a step when they're stuck, never just the answer to copy. Built to support your school's and NESA's approach to AI.

See the progress

Add yourself as a sponsor for a simple dashboard: a readiness snapshot showing where they stand now, and how it improves as they practise. Measurable progress, not just hours logged.

Always on hand

On hand whenever they have a moment, with no booking and no scheduling around a tutor's calendar.

🔒

Safe with their work

Their work is theirs. We're clear about how data is handled, and we don't sell it.

A learning tool you can stand behind. It gives feedback, not answers, so it supports academic integrity rather than undermining it.

Feedback, not answers

Scaffolds and questions that prompt the student's own thinking, with no model answers to copy.

Acknowledgement log

Students can produce a log of feedback received and changes made, helpful if your school asks them to declare the work is their own (e.g. NESA's "All My Own Work").

Syllabus-aligned

Marked against a verified answer key and the NSW syllabus: exact, and consistent with how the HSC awards method and answer marks.

School & centre licensing

Per-seat or site licensing for your class, faculty, or tutoring centre.

Questions, answered

Is this cheating?

No. RedTexta teaches you the method and gives feedback on your own working, and doesn't do the question for you. For exam prep and practice, it's just like getting a tutor's help.

Is it a real person?

No, it's automated, so you don't have to book a time. Because the answer to every question is worked out in advance, the marking is exact rather than guessed, and it teaches the fix the way a great teacher would.

What about my privacy?

Your work is yours. We explain clearly what we keep and for how long, we don't sell your data, and you can delete it.

Which subjects can I use?

Live now: NSW HSC Maths Standard 2. More subjects will appear here only once they're genuinely ready, and we'll tell you when yours lands.

Do I need to download an app?

No. RedTexta works in your browser on your phone, tablet, or laptop, and you can add it to your home screen like an app if you want.
