Sound familiar?
You didn't sign up to be the tutor.
But here you are picking topics, marking answers, deciding what to do tonight. The work the tutor or platform should be doing, you're doing. Most evenings, badly, because you're tired.

"The tutor's good. But it's one hour a week. The other six days, we're just guessing."
— James, dad to Oliver (Year 4, North London)
Stuck on a fractions question
"He asks me how to do it. I learned it differently. We end up both frustrated."
— Priya, mum to Ayaan (Year 5, Birmingham)
Tests bought, never marked
"I bought the practice papers in September. It's January. Three are done. None are marked."

StageX Academy Here to help
"This is exactly what I'm here for.
Let me take this off your plate."
How it works
Three steps. Then it just runs in the background.
- 01 Step 1
Your child practises every day
They log in, see their plan for the day a quick test, some revision cards, a topic to study. About 20 minutes. No decisions needed.
Practice - 02 Step 2
Lumi figures out what's next
Every answer goes in. Every pattern comes out. Where they're guessing. Where they're coasting. Where the gap is. Tomorrow's plan is built from what today's showed.
AI watches - 03 Step 3
Stuck? Lumi explains it right there.
Got it wrong? They tap once and Lumi walks through it the actual numbers, the actual mistake, step by step. No waiting. No awkward parent maths moments.
Help + visibility
The plan adapts every day. You stay informed without lifting a finger.
What changes when Lumi takes over the planning.
Not a sales pitch a week. Three moments. The kind a parent currently spends planning, marking, or worrying about.

Why is 3/4 + 1/3 not equal to 4/7?
Great question! You can't add fractions unless the denominators match.
Think of it like adding slices from different-sized pizzas…
- Explains in plain English, not textbook jargon
- Covers any topic - ask follow-up questions freely
- Teacher tone: patient, clear, encouraging

Q1 · Mathematics
easy
Look at the distance-time graph. What is the speed of the car?
A
20 km/h
40 km/h ✓
C
80 km/h
D
160 km/h
Correct — here's why
Speed = Distance ÷ Time. Read from the graph: 80 km ÷ 2 hours = 40 km/h ✅

With StageX Academy
What Tuesday feels like
😩
Tuesday, 9:14 pm
"Which book tonight?"
Six 11+ books on the table. No idea which one. She's already in bed.
✨
Tuesday, 6:00 am
Plan already waiting.
Built overnight. 3 tasks, 22 minutes, targeting exactly what she needs.
😩
Tuesday, 8:30 pm
"Who marks this thing?"
You do. After the kids are in bed. The pile grows.
✨
Tuesday, 4:31 pm
Every answer marked.
The moment she submits. Every error explained. You don't touch it.
😩
Every Tuesday
£30. One hour. Then what?
Great session. Then five days with no plan.
✨
Every day
A plan built from today.
Lumi adjusts tonight's plan from what she did this afternoon.
😩
Sunday night
"Is she actually improving?"
You don't really know. She says she's fine. Probably.
✨
Tuesday, 8:00 am
Thirty seconds. You know.
Streak, scores, weak topics. Everything before your coffee goes cold.
😩
Night before exam
She's never done a timed test.
The real 11+ will feel nothing like what she's been practising.
✨
Months before
The exam feels familiar.
Dozens of timed GL and CEM-style papers already sat. Exam day is just a Tuesday.
£200+/month.
One hour a week.
Six days of guessing.
A fraction of the cost.
Every single day.
Nothing to mark. Nothing to plan.

Honest about what Lumi isn't
Because over-promising is how trust dies.
Lumi is a serious, structured self-study platform but it isn't everything. Before you sign up, here's what you should know it doesn't do:
- It's not a live tutor. There's no human on a video call. If your child needs 1:1 explanation, Lumi works alongside a tutor, not instead of one.
- There are no video tutorials. Content is written, with worked examples not someone talking on screen.
- It's not for SATs specifically. Focused on 11+, though much of the content overlaps with KS2.
- No printable worksheets. Everything is on-screen, on any device.
- There's no guarantee. No platform can promise an 11+ pass but with proper, daily practice, Lumi gives your child the best chance of one.
With a tutor or without one. StageX works either way.
Some families use StageX alongside a tutor. Others use it instead. Both work because what matters is consistent daily practice, and StageX makes that happen automatically.

-
What ages is StageX Academy for?
Most children using StageX Academy are in Years 4 to 6 the 11+ prep window. It also works as solid KS2 enrichment for younger children, and older children using it for general confidence in these subjects.
-
Which exam boards does StageX Academy cover?
Content aligns with GL Assessment, CEM, ISEB Common Entrance, and general 11+ topics. You can target one board, or practise across all of them.
-
Does my child still need a tutor?
Honestly, most families find they don't need both. Lumi handles daily practice, marking, revision and weak-area targeting which is the bulk of what a tutor does. If your child needs someone to sit next to them and hold their hand through hard problems, a tutor still helps. But if you're using a tutor mainly because you don't know what to give your child to do Lumi does that part.
-
How long should my child use StageX Academy each day?
20 minutes is plenty. The plan is built for that. What matters more than time is doing it consistently a daily 20 minutes beats an occasional hour every time.
-
What devices does StageX Academy work on?
Any modern web browser laptop, tablet, phone. No app to install. Progress syncs across devices automatically.
-
Is my child's data private?
Yes. No ads. No data sale. UK-hosted. Parent-controlled accounts. We never share data with third parties for marketing.
-
Can I see what my child is doing?
Yes the parent dashboard shows everything: tasks completed, time spent, scores, subject mastery, the full AI plan history.
-
What if my child finds it too hard or too easy?
The system adapts to their level practice gets harder as they improve, and the AI plan focuses on weak topics. You can also skip or prioritise topics from the parent dashboard.
-
Can I cancel?
Anytime. No notice period. No retention games. The annual plan can be refunded pro-rata in the first 30 days.
-
What if my child finishes all the content?
The question bank and revision deck keep growing. Spaced repetition means cards loop back at the right intervals even after 'mastered' so retention stays strong all the way to the exam.
