Linear Equations & Systems
Linear equations, lines, systems, inequalities, modelling, Desmos strategy and a large official-question-bank paraphrase workshop.
DIGITAL SAT MATHEMATICS · CF MATHS NOTES
The SAT library now begins with three complete chapters. Each chapter pairs narrative lecture notes and worked examples with a separate worksheet for independent practice.
CHAPTER LIBRARY
Each pair is designed to work in order: learn the structure in the lecture notes, then complete the worksheet without the worked examples beside you.
Linear equations, lines, systems, inequalities, modelling, Desmos strategy and a large official-question-bank paraphrase workshop.
Ratios, unit rates, proportional relationships, scale factors, percentages, repeated change and real-world SAT modelling.
Function notation, interpretation, linear and exponential models, quadratic features, transformations and graph-based problem solving.
HOW TO USE THEM
Read the narrative explanation and cover each worked solution before attempting it.
Move to the worksheet and complete the whole set before checking the collected solutions.
Repeat the questions that were slow or uncertain under a short time limit.
Use SAT practice and mock modules once the separate chapter methods are secure.
