Year 9 Algebra: The Crash Course
Year 9 algebra, where quadratics arrive. Indices and standard form, factorising, simultaneous equations and curved graphs, engineered into 57 pages you can master in one afternoon.

Overview
This is the whole Year 9 algebra year, rebuilt for revision and one clear level up from Series No. 02. Fifty-seven pages take a student from negative and zero indices and standard form, through binomial products and factorising, into simultaneous equations, deep rearranging, quadratic sequences and the first curved graphs — then straight into an Exam Lab that rehearses it all under pressure.
It is designed to be skimmed in thirty minutes the night before a test, or worked through properly in two to four hours for a genuine, lasting grip on the year. Every calculation and worked solution has been verified, and the coverage is checked against the shared core of the UK, US, Canadian, Australian, New Zealand and Singapore programmes.

- Rearrange formulae with squares and roots without losing signs or steps
- Find the nth term of a quadratic sequence and recognise the shape of any curved graph
What’s inside
Formula library
Glowing formula cards: the rule, what it means, when to use it, why it works, and a worked example.
3-level worked examples
Every method shown at three levels of difficulty, so the step up is never a cliff.
Trap-and-fix pairs
The wrong working beside the right working, so misconceptions get corrected on sight.
32 numbered key facts
The non-negotiables of the year, numbered 01–32 for fast last-minute review.
The Mistake Museum
Twelve exhibits of the errors that cost real marks, each one defused.
Exam Lab + cheat sheets
The LAUNCH method, worked missions, a 24-question mixed review with solutions, and two cheat sheets.
