For students
Find out what you actually know before the exam does
Re-reading your notes feels like revision and is not. Answering questions and marking them honestly is. This is a library of questions, by topic and by level, with worked answers behind every one.

Why it works
Revision that tells you something
The point of practice is finding the thing you have wrong. Everything here is built around making that happen sooner.
Worked answers, not just the answer
When you get one wrong, the solution shows every step - so you can see which line your working went off, rather than staring at a number that does not match yours.
One topic at a time
Filter to moles, or organic mechanisms, or electrochemistry. Revising the thing you are avoiding is much easier when you can find it in two clicks.
The mistakes that cost marks
Misconception sets are built around the errors students actually make. They are worth doing precisely because you will probably get some wrong.
Written by a chemistry teacher
Someone who has marked thousands of these papers wrote the questions, the distractors and the mark schemes - so what you practise is what the exam asks.
Fifteen minutes counts
Rapid recall is fifteen quick questions across topics you did weeks ago. It is the cheapest way to find out what has already faded.
Your specification, your board
GCSE, iGCSE, AS and A Level, mapped to AQA, Edexcel, OCR and CIE - so you are not practising content that is not on your paper.
How to use it
A way to revise that is not just re-reading
You do not need a revision timetable to start. You need one topic and one honest attempt.
Start with what you are avoiding
Pick the topic you would rather not think about and do the misconception set for it. Getting things wrong here is the entire point - it is cheaper than getting them wrong in June.
Do the questions properly
Work through the topic sheet with the answer pack face down. Marking as you go feels faster and teaches you nothing.
Mark it honestly
Then open the worked answers and mark against the scheme. The marks you did not get are your revision list for next week.

Fair questions
- Is this just past papers?
- No. Past papers are free from your exam board and you should use them. These are teaching resources: questions grouped by topic so you can drill one thing, with worked answers that explain the method rather than mark schemes that assume you already know it.
- I am not sure which level I am on.
- GCSE and iGCSE are the exams most people sit at 16; AS and A Level at 17 and 18. If you are unsure, your exam board and specification code are on the front of any past paper your school has given you.
- Can I print them?
- Yes - they are PDFs made to be printed and written on. You can also work through them on screen if you would rather.
