Numbers and Logic

While applying for jobs, I kept coming across numerical and logical reasoning tests, and could never find enough questions to practise with. So I built Whetstone, which generates fresh questions every time and explains the mistake when you get one wrong.

Practise word problems, tables and charts, deductive puzzles, and number, letter and figure series. You can practise without a clock, or sit a timed test.

Whetstone is free and open source, and its code is on GitHub. If a question looks wrong, use Report a problem on it and I’ll fix it.
