CoreMark Coach · Cambridge Lower Secondary · Stages 7, 8 and 9

A PDF can't answer back. Coach can.

Coach is an AI tutor built on the CoreMark boosters. It teaches a topic step by step, sets exam-style papers, marks them, and brings back the topics your child finds hard for a quick review. It runs in your own Claude account, and once you have one, setting it up takes under a minute.

Made for Claude Free Claude account works Set up in under a minute Stages 7, 8 and 9

Two modes

Learn it. Then prove it.

Your child picks a mode and a topic, and Coach takes it from there. Every topic for your child’s stage in Maths, Science and Computing is covered.

Learn mode

Taught, not told

Say "learn" and a topic, like "learn Angles".

  • Pictures first. When a topic needs one, Coach draws a diagram for you in Claude.
  • An everyday example first, then the rule, then the mistake most students make.
  • "Teach it back to me." Your child explains it in their own words, so Coach can see what really stuck.
  • Fixes mistakes kindly, then shows how to write it the way examiners want.
  • Starts from the basics, or from wherever your child is.

Exam mode

Practice that feels real

Say "exam" and a topic, like "exam on Fractions".

  • Three sizes: a quick topic test, a longer practice paper, or a full Checkpoint-style mock.
  • One question at a time, like a real paper. No hints mid-paper on a mock.
  • Marked after you submit: method marks, accuracy marks, and the first step that went wrong.
  • Drawing questions: draw on paper, upload a photo, and Coach compares it with the correct drawing.
  • A clear report grouped by idea, not by question number, with what to practise next.

See a real session

This is what a session looks like.

Excerpts from real sessions with Coach. The student's answers are shown exactly as they were typed, mistakes and all.

What Coach does

A patient tutor, any time your child is ready.

Coach is designed to be warm and encouraging, and to teach in short, manageable steps.

Brings weak topics back

Coach notes which ideas were shaky and offers a quick review of them at the start of later sessions.

Finds the real gap

If a mistake comes from an earlier stage, Coach spots it, calls it a foundation gap, and patches that first.

Fresh questions every time

New questions each session, as many as your Claude plan allows. A booster stops at 20.

XP, levels and streaks

Progress your child can see. XP rewards effort and fixed mistakes, not just repeating easy topics.

Diagrams on the spot

Angles, circuits, cells, graphs and flowcharts, drawn by Coach in Claude whenever a question needs one.

Exam date mode

Tell Coach when the exam is, and it focuses on the weakest and highest-value topics first.

Adjusts on a hard day

If your child says it's too hard, Coach shortens the paper or switches to teaching. Mistakes are framed as gaps to close, never failures.

Stays on its stage

Each Coach is set up to teach one stage and politely redirects requests for other stages. It may revisit earlier foundations when it spots a gap.

PDF boosters vs Coach

Same CoreMark care. Now it talks back.

The boosters are great for focused practice on paper. Coach turns that same material into a conversation.

Better together

Coach was designed as an extension of the boosters' feedback: the same summary-sheet rules, the same marking style, the same common-mistake notes. Print a booster for paper practice, then use Coach when your child needs it explained.

How it works

Set up in under a minute.

No software to install and no instructions to paste. You add one file to Claude, once.

01

Open Claude

Sign in at claude.ai with your own account (the free plan works). Go to Projects, then New project.

02

Add your Coach file

Upload the Coach file for your child's stage (CM_AGENT_S7.md, CM_AGENT_S8.md or CM_AGENT_S9.md) to the project's files. That is the only file.

03

Check two settings

Check Memory is on (Settings → Memory) and turn on Code execution and file creation (Settings → Capabilities). Memory carries progress; the second setting lets diagrams show.

04

Say "hi"

Open a chat inside the project and type "hi". Coach introduces itself and asks what your child wants to do.

Each stage has its own Coach file, so pick your child's stage. Using more than one stage? We recommend a separate Claude project for each.

What you need

Made for Claude. Only Claude.

Coach runs inside Claude, the AI assistant made by Anthropic. Here's what that means for you.

A Claude account in your name

Claude's terms require account holders to be 18 or over. So the account is yours: you set it up, run Coach from it, and stay involved while your child uses it.

Free works. Pro helps for long sessions.

Coach works on Claude's free plan, diagrams included (turn on Code execution and file creation in Settings → Capabilities). For long study sessions or full mock papers, Claude Pro gives more room before you reach the free plan's limits. See Claude's plans.

Not for ChatGPT or other AIs

Coach is made for Claude only. It won't work in ChatGPT, Gemini, Copilot or any other AI app. Set it up on a computer at claude.ai for the smoothest start.

Safety and accuracy

Built with care. Best with you nearby.

We've taken great care to make Coach child-friendly. Guardrails are built into every Coach file, and its questions, answers and diagrams each get a check before your child sees them. Even so, we recommend a parent supervises. Claude accounts are for adults (18+), so run Coach from your own account and stay nearby, especially in the first few sessions.

  • AI can get things wrongIf something looks off, ask Coach to show its working, or check the booster solutions.
  • Your school's order may differCoach follows the curriculum for your child’s stage. Tell it what they are studying now.
  • IndependentNot affiliated with Cambridge or Anthropic.

Tips

Get the most out of Coach.

A few habits make a big difference, for your child and for you.

For students

  1. Teach it back properly.Explain in your own words, not Coach's. That's where real understanding shows.
  2. Show your working, even in practice.Coach gives method marks, just like the real exam.
  3. Short and often beats long and rare.Twenty to thirty minutes on most days works better than one long weekend session.
  4. Say yes to the quick reviews.When Coach brings an old topic back, that's exactly when it's about to stick.
  5. Ask "why?" any time.Even in the middle of a lesson. Coach will explain it a different way.
  6. Test yourself a day or two later.Exam mode works best once a topic has had a little time to settle.

For parents

  1. Sit in for the first few sessions.See how Coach teaches, then stay nearby while your child works.
  2. Read the end-of-exam report together.It groups mistakes by idea, so you both know what to work on next.
  3. Tell Coach the exam date.It switches focus to the weakest and highest-value topics.
  4. Pair it with a printed booster.Paper practice for exam stamina, Coach for the bits that need explaining.
  5. Praise effort, not just scores.Streaks and XP reward turning up and fixing mistakes. Celebrate those.
  6. Start a fresh chat for each session.Coach is designed to pick up from memory, and shorter chats are easier to look back through.

FAQ

Questions parents ask us.

Does my child need their own Claude account?

No. Claude's terms require account holders to be 18 or over, so Coach runs from a parent's Claude account. Set it up yourself and stay involved while your child uses it.

Do I need Claude Pro?

No. Coach works on Claude's free plan, diagrams included. For long study sessions or full mock papers, Claude Pro gives more room before you reach the free plan's usage limits. See Claude's plans.

Does it work with ChatGPT, Gemini or other AI apps?

No. Coach is made for Claude only. It does not work in ChatGPT, Gemini, Copilot or any other AI app.

What exactly do I get?

One Coach file for your child's stage, plus a short setup guide, sent by email after payment. You add the file to a Claude project once, and that's it. There's nothing to install.

How long does it last?

Each Coach file covers one school year and runs until the end of June. After that, Coach signs off for the year, and we’ll email you about the next edition.

Which stages are available?

Stage 7, Stage 8 and Stage 9 launch together. Each has its own Coach file and is set up to teach only its own stage. Reserve your spot to hear the moment they open.

Can it start from the basics?

Yes. Your child can start from the very beginning of a topic or jump to any point. Coach also checks earlier-stage foundations and patches any gaps it finds before moving on.

Does Coach remember my child's progress?

Coach is designed to use Claude's memory to pick up between chats and to note weak topics for review. Memory is a Claude feature, so we can't guarantee it saves every time; keep it switched on. If Coach loses track, tell it where you left off and it will carry on from there.

Can Coach get things wrong?

Occasionally, yes. Coach checks its questions, answers and diagrams before showing them, but no AI is perfect. If something looks off, ask Coach to show its working, or check the booster solutions. If it finds its own mistake, it says so and replaces the question.

Does it follow my school's chapter order?

Coach follows the Cambridge Lower Secondary curriculum for your child’s stage, but schools teach chapters in different orders. Tell Coach what your child is studying now, and it starts there.

How is this different from the PDF boosters?

A booster is a fixed set of 20 questions with worked solutions, great for practice on paper. Coach explains, asks follow-up questions, sets as many questions and papers as your child wants, marks them, and brings weak topics back. Many families will use both.

How long is the early-bird price available?

The ₹4,999 price is for the first 100 families. Drop your email to lock it: you get Coach at ₹4,999 instead of ₹9,999.

What happens when I reserve my spot?

You don’t pay anything. We lock the early-bird price for you and email you the moment Coach opens. If you change your mind, unsubscribe from any email.

Is CoreMark affiliated with Cambridge?

No. CoreMark is independent. Coach and the boosters are original practice material, not affiliated with or endorsed by Cambridge Assessment International Education.
