Questions students ask
Which exam boards does A Level Chemistry cover?
AQA, OCR A. Choose your board when you open the app; the topic practice and mock tests follow it. You can change board in Settings.
Does it work for AS as well as the full A level?
Choose AS or A Level in the app. The course filter follows your selected board: content that is AS for AQA can be A Level only for OCR A, and vice versa.
What can I do for free?
The free tier opens the first available subtopic of each topic and the first reference-card category; the same 660 free questions are on this website. A subscription or a one-off lifetime purchase unlocks all topics: 2,900+ questions and 210 reference cards.
How are required practicals covered?
Practical revision is organised by technique, with AQA required practicals and OCR A Practical Activity Groups mapped to the relevant topics. Use the questions and notes alongside supervised practical work at school or college.
Does it say which facts and formulae I need to learn?
The 210 reference cards carry board-specific labels: "In your booklet" when the core information is printed in your exam data or formula booklet, and "Learn this" otherwise.
