About us
Original questions. Real exam style. No shortcuts.
KodonKlasses is a product of Kodon Systems — built by people who were frustrated by photocopying textbooks and pasting from PDFs, so we built the tool we wished existed.
What we do
We write original Maths questions modelled on the structure, difficulty and marking culture of real exam boards — Edexcel today, expanding to AQA, OCR, GCSE, IGCSE, CBSE, ICSE, IB and IAL. Every question is checked before it enters the bank. Tutors build worksheets in minutes; students practice with weekly sets matched to their year.
Our promise
Every question is original — never copied from past papers or textbooks. Every machine-checked answer is mathematically verified before it reaches you. No advertising, no tracking, no selling your data. Just practice that works.
Who it's for
Students in Years 7–13 (Grades 6–12) who want to practice the way they'll be examined, and the tutors who teach them. If you teach or study any of the boards we cover — or the ones we're adding — KodonKlasses is being built for you.
Our policies
We take data protection seriously — especially for young users. We collect the minimum needed to run the service, we're registered with the UK's Information Commissioner's Office, and accounts for children are managed by parents.
