A-level chemistry games, generators and revision tools
Free resources and games to support A-Level and AS-Level chemistry students across OCR A and AQA. Most resources also help with other exam boards, but specification differences are labelled where they matter.

Exam-board chemistry games
Use the board pages as revision maps. Shared material is reused where safe; AQA and OCR A differences are not quietly merged.

Calculation tools and simulations
Each generator creates fresh numerical data and exposes the reasoning after you have attempted the question.
Back titration generator
Purity calculations using a measured excess, dilution and aliquot titration.
Generate questions →Isotope problems
Relative atomic mass and unknown abundance calculations at two levels.
Practise isotope maths →Rate equation generator
Initial-rates tables, reaction orders, rate equations and rate constants.
Generate a rates question →Arrhenius equation
Two-temperature calculations and activation-energy practice.
Understand Kc
Build equilibrium expressions and calculate equilibrium constants.
Boltzmann distribution
Explore temperature, activation energy and catalyst effects.
Retrieval practice
Topic quizzes that bring errors back
Wrong statements return later in the same run. Explanations appear immediately and weak items can be saved locally for another day—no account required.
Study strategy
Not sure what to change?
The study-habits diagnostic turns vague advice into specific actions for calculations, organic chemistry, exam technique and spaced retrieval.
