Mixed practice – not an official exam

These newly written problems offer general math practice. They are based on a Swedish selection of topics, not aligned with any country's exam or curriculum. Difficulty may differ from local tests.

Topics on this sheet

These groups describe the exercises, not a local curriculum:

  • Number sense · 1Powers, square roots and scientific notation.
  • Algebra · 3Algebraic expressions, equations and systems of equations, square rules.
  • Geometry · 5Pythagoras' theorem, circles, volume, distance and scale.
  • Probability and statistics · 2Probability and averages such as the mean.
  • Relationships and change · 5Linear functions, proportionality, percentage change and interest.

About this generator

For broad revision, pupils need mixed practice, not one topic at a time. Each sheet picks problems in turn from equations, systems of equations, Pythagoras, linear functions, percentage change, interest, powers, probability, volume, circles, proportion, square rules, mean and scale. Choose words, calculations or a mix, and create a new version for another round. The topics are based on a Swedish selection and do not match any specific national exam. The answer key is calculated by the website, so it always matches the tasks. No sign-up is needed and no personal data is collected.
