Able at primary. Coasting at secondary?
Our 5-Level online Booster Course challenges children aged 11 to 14.
Simple to complex practice exercises, extensive review quizzes and explainer videos develop a deep, connected understanding across number, algebra, and geometry.
Is your child ready for the challenge?
Our two-section readiness test, about 30 minutes in total, will let you know if the course is right for them. Free, and nothing to sign up for.
Try the testThe usual answer is to rush them ahead.
We do the opposite.
When a child finds maths easy, they're often moved onto next year's topics.
We don't. We take the ideas they have already met and go broader and deeper.
Find the value of n.
A hexagon. A perimeter. A power.
Nothing here is beyond your child's reach — and yet most 12-year-olds who get full marks in class tests cannot do it.
Challenged, not accelerated
We take topics from early secondary and present questions that demand deep mathematical thinking.
Connected, not boxed
Most maths at this age is taught one topic at a time, so integrated questions such as these are often what bright children are least prepared for.
Retained, not forgotten
A quiz for every exercise and full reviews for every tier, so there is plenty of practice to return to, ensuring ideas are retained.
One quiz. Five topics.
A Low-Stakes Quiz from the Circumference tier. It asks about powers, index laws, perimeter, expanding brackets — and circumference. Down the side: seven more quizzes just like it, in that tier alone.
Instead of next stage's work early — this year's ideas, properly, connected, and still there in time to come.
Our whole programme, one payment.
Five core topics covering the Multiplication Law of Indices, Perimeter, Algebraic Expressions, Circumference, and Integer Addition & Subtraction.
Online Textbook
5 carefully crafted Learning Tiers. Tiers, not chapters, as each one subsumes the previous one to develop complexity.
Low-Stakes Quizzes
A dedicated low-stakes quiz for every exercise, plus full Learning Tier reviews. High variation deepens thinking.
Answer Library
Answers to each Exercise, Low-Stakes Quiz, and Full Learning Tier Review for students to check their progress.
When your child gets stuck, they can watch it worked through.
Every exercise in the book has its own worked-example video — 44 of them, each one a question taken step by step on screen, the way it would be explained in a classroom.
They are free on our YouTube channel and are not part of the £79.
For children who find their current Maths work easy —
and relish the challenge of deeper thinking.
Our 5-Level Booster Course challenges 11–14-year-olds in a way schools conventionally don't. Crucially, Maths isn't a list of disparate topics, each with their own rules and methods. Instead, it's an interconnected whole. With Simple to Complex, Maths is presented as such, with each new Step requiring mastery of the previous one.
£79 for 12 months access.

Worth comparing
A private Maths tutor in the UK typically charges £30–50 an hour. The Booster Course costs less than two hours of tutoring — for a full year of structured mathematics the whole household can use.
And unlike a weekly session, it's there whenever your child is: after school, at weekends, through the holidays.
Get accessWho is it for?
Able, interested children at the end of primary and the start of secondary school — approx. ages 11–14. It's a challenge and boost programme, not a catch-up scheme: it stretches children who find Maths easy and makes them excel further.
What exactly do we get?
The complete Simple to Complex Mathematics Booster Course in the online reader, extensive library of Low-Stakes Quizzes, and a full Answer Library. Worked-example videos are available free on YouTube.
Does one membership cover siblings?
Yes. It's priced per household, not per child — brothers and sisters share the same membership at no extra cost.
We home educate. Does it fit?
Very well. The programme is a complete, structured spine that will allow you to benchmark your child's level and progress in mathematics.
How is it different from Maths apps?
Apps drill fragments. This is a full curriculum, written as a book by practising teachers and backed by the research on how children actually retain mathematics.
What if it isn't right for us?
Email us within 14 days of purchase and we'll refund you in full, no questions asked. It's a one-off payment, so there's nothing to cancel — your access simply runs for 12 months from the day you buy. One thing to know before you get there: at checkout you tick to start your access straight away, and under UK law starting straight away means the automatic 14-day cancellation right no longer applies. Our own refund promise is separate from that, and is unaffected.
