How it works

From a practice paper to a mark you understand, in four steps

The same journey every week: you set the work, your child does it, and you can see what happened to every answer.

  1. Step 1: Choose a whole paper, or single questions

    Assign a whole practice paper in one step, filtered by assessment type (such as WA1 or prelim), level, year and difficulty. Or pick single questions from the same bank. Every question was built from past primary-school exam papers and checked by a reviewer before it was published.

    Illustration: adding questions to a new assignment. Made-up data.

  2. Step 2: Your child answers online or on paper

    Typed answers, numbers and multiple choice on a laptop or tablet, saved as they go, and the page always says whether it has saved. Prefer paper? Your child can photograph a handwritten answer inside the paper, or you can upload a worksheet photo or PDF.

    Illustration: a question with its answer saved. Made-up data.

  3. Step 3: Marked, and every mark says how

    Exact answers are marked automatically against the published answer key. Written working is marked by AI and says “Marked by AI”. You do not approve each mark: if you think one is wrong, question it in one line and it is checked again automatically.

    Illustration: a submitted paper with automatic marks, an AI mark and a mark the parent questioned. Made-up data.

  4. Step 4: Learn from the marks

    After marking, your child sees worked solutions and can retry once after feedback. Progress shows the marks actually received, grouped by topic. No predicted grades, no mastery scores: a plain record you can talk through together.

In the app today

Everything a parent needs to run practice at home

All of this is built and in the private beta. We start with PSLE Mathematics; more levels and subjects will follow.

  • Whole papers in one step

    Assign a complete practice paper, filtered by assessment type, level, year and difficulty, or build your own set of questions.

  • Handwritten worksheets

    Your child photographs a handwritten answer inside the paper, or you upload a photo or PDF of a worksheet. It is read and marked like any other answer.

  • AI marks you can question

    Written working is marked by AI against the marking scheme. AI marks are final; question any one in a line and it is re-checked automatically.

  • Worked solutions and a retry

    After marking, your child sees how each question is solved and can try again once. You can switch retries off.

  • Review sets

    Build a mixed review set from questions your child has already answered and had marked. You preview it, then publish it like any assignment.

  • Hints and Ask for help

    Hints written with each question, a gentle “need a hand?” prompt, and an Ask for help note that goes to you, never to an AI.

  • Question a mark

    Think a mark is wrong? Question it in one line. An answer-key mark is re-checked at once; an AI mark gets an independent second review, and you can then ask a person once.

  • Study library

    Study guides, flashcards, mind maps, revision sheets and more, written once by our team, reviewed, and shared with every family.

  • Progress from real marks

    Marks your child actually received on submitted work, by topic. No predictions, no ability labels.

AI, kept in its place

AI helps with the marking. You can always question it.

Tuition Guru uses Claude, made by Anthropic, for one narrow job: reading and marking written working against the published marking scheme, with your permission. Every AI mark can be questioned, and a person can be asked to look.

What the AI does

  • Marks each part of the marking scheme, such as method and working.
  • Gets a second, independent AI check when it is unsure, and your child gets the higher mark.
  • Labels every mark “Marked by AI”, so you always know where a mark came from.

What it never does

  • Mark anything without your permission. Without it, no AI mark is given.
  • Chat with your child. There is no chatbot, and nobody can message them.
  • Diagnose, label or predict your child's ability or grade.
  • Overrule the published answer key. Exact answers are checked against it directly.

You stay in charge

Every mark tells you where it came from

You do not need to check every answer. Each mark says how it was given, and you can question any of them.

Marked
Final, from the published answer key. Multiple choice, numbers, fractions and units are checked exactly.
Marked by AI
Final, for written working, against the marking scheme. Where the AI was unsure, a second AI checked it first.
Mark questioned
You think a mark is wrong. It is re-checked automatically, and you get a reply in plain words.
Ask a person to look
Still disagree? A Tuition Guru reviewer keeps the mark or re-marks it, and tells you why.

Marks are never overwritten. Every version, including the AI mark and any re-check, is kept in the question's history.

Privacy and safety

Built for children, controlled by parents

Tuition Guru is used by primary-school children, so the rules are strict and written down.

  • Your permission first

    Nothing is sent to an AI service without your separate permission for each child. You can refuse or withdraw it at any time without losing anything that does not use AI.

  • You remove the details

    Before a worksheet page is sent for AI reading, you black out names and school details and approve the copy that will be sent. Your original upload is never sent.

  • Where your data is kept

    Your family's records and uploads are kept in our Singapore-region database and storage. The one exception is the optional AI step, which runs outside Singapore, as the privacy notice explains.

  • Photos do not linger

    Worksheet images are deleted after 90 days. We do not sell personal data, and we do not use it for advertising.

  • One parent account per child

    Each child is linked to one parent account, which creates and controls the child's login. We do not ask children for personal details, and there is no chat or messaging anywhere.

  • Erase it when you are done

    From your account page you can erase one child's data, or your whole account. We keep only a name-free record of the permissions you gave, for 24 months.

Read the full privacy notice and the AI and child safety statement. We hold no certification and claim no endorsement: we would rather tell you exactly what we do.

Questions

Questions parents ask us

Who is Tuition Guru for?
Parents of primary-school children preparing for PSLE Mathematics, who want to set the practice themselves and see exactly how each answer was marked. We start with PSLE Mathematics; more levels and subjects will follow.
How do I join the private beta?
The beta is invitation-only and open to up to 25 families. Email us to request an invitation. If there is a place, we send an invitation to your email address, and you sign up with that address. You then invite your child from your own account.
What does it cost?
The first month is free during the private beta. After that the planned prices are in the Pricing section. Billing is not switched on yet: there is nothing to pay today, and we will tell you before any charge.
Are these official PSLE questions?
No. They are PSLE-aligned practice questions built from past primary-school exam papers, with names and school details removed. Every question is reviewed and published by our team before it appears in the question bank.
Does the AI mark my child's work by itself?
Yes, for answers the answer key cannot check, and only with your permission. Exact answers, such as multiple choice and numbers, are checked automatically against the published answer key. Written working is marked by AI and labelled “Marked by AI”, and your child sees the mark when marking finishes: you do not approve each one. Where the AI is unsure, a second, independent AI checks the mark first. You can question any mark, and a person can be asked to look.
Is AI marking switched on already?
Not yet. Before it is turned on for the beta, it must first pass our own tests on made-up practice answers. Until then, written working waits for a mark, handwritten answers and worksheets are kept with your child's work but not read by AI, and everything else works as normal.
Does my child talk to the AI?
Never. There is no chatbot, nobody can message your child, and children cannot send anything to the AI themselves. Only a parent can choose to use AI, with separate permission for each child.
What if I disagree with a mark?
Question it in one line from the marked paper. A mark from the answer key is re-checked straight away; an AI mark gets an independent second review, and you are told the outcome in plain words. If you still disagree, you can ask a Tuition Guru reviewer once, who sees the answer and the marking scheme but not who you are. You cannot change a mark yourself, and every earlier version of the mark is kept.
What happens to worksheet photos?
Worksheet images are deleted after 90 days, and photo details such as location are removed when you upload. The privacy notice explains exactly what we keep and why.
Can I stop using AI, or leave?
Yes. You can refuse or withdraw AI permission at any time without losing anything that does not use AI. You can erase one child's data, or your whole account, from your account page. You can also ask us what we hold about you, or ask us to correct it.
