Ratio, proportion and rates of change

Flashcards

Formulae, definitions and method prompts for GCSE and A-level maths, drilled with spaced repetition.

Maths in Science

The maths skills AQA tests inside GCSE science (at least 30% of Physics marks) — standard form, significant figures, percentages, rearranging equations and graph gradients — each with a method, a worked example and practice in a science context.

Revise by topic

Edexcel maths topic by topic — each page has the ideas on one screen, the marks the mark schemes report students losing, exam-style drills with full working, and a printable question pack.

Step-Up Maps

Moving up a level? See strand by strand exactly what's new — GCSE to A-level, GCSE to L2 Further Maths, and A-level to Further Maths — so you prepare the right things over the summer.

Worked Examples (faded)

Learn a method the way the research says works — see it fully worked, then fill in the blanked steps, then do it cold. From completing the square and the quadratic formula to the chain rule, integration by parts and partial fractions.

Mental Maths Trainer

A fast, Zetamac-style arithmetic drill — add, subtract, multiply and divide against the clock. Configurable ranges, a two-minute sprint and your best score saved in your browser.

Standard Form Trainer

Spot the correct A × 10ⁿ form — the right mantissa (1 ≤ A < 10) and power of ten. Ten quick multiple-choice questions with instant marking.

Rounding Trainer

Drill rounding to significant figures and decimal places — ten quick questions with instant marking. The free-marks skill every science paper tests.

Circle Theorems

All 8 circle theorems in the exact wording examiners want for the reason in a proof, with a tap-to-reveal recall drill.

Formulae to Memorise

Exact trig values, mensuration, the quadratic formula, trig identities and standard calculus results — the formulae worth knowing cold, with a recall drill.

Calculator Guides

The Casio fx-CG50 and fx-991 ClassWiz in the exam — graphs, the equation solver, statistics, distributions and numerical calculus, organised by the question type that needs them.
