Able at primary. Coasting at secondary?
Our 5-Step online Booster Course challenges students in early secondary school.
Simple to complex practice exercises, extensive review quizzes and explainer videos develop a deep, connected understanding across number, algebra, and geometry.
Our whole programme, one subscription.
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.
For children who find their current Maths work easy —
and relish the challenge of deeper thinking.
Our 5-Step 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.
Subscribe nowWho 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 subscription 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 subscribing and we'll refund you in full, no questions. After this, you can cancel any time and keep access for 12 months from the initial purchase date.
