Before you start

One timer of 25 minutes runs for the whole set; the test submits itself when it ends.
Every question is worth 1 mark and a wrong answer costs nothing, so leave nothing blank. That is not how the source exams mark these questions, which means a score here is not comparable with the same questions attempted inside an exam mock.
Answers and remaining time are saved in this browser, so a reload will not lose your work.
Your result appears the moment you submit, with a worked explanation for every question.

Where these questions come from

Every question in this set already appears in the reasoning section of a real exam mock on this site. Reasoning is the one part of a paper that is not exam-specific, so the same puzzle is legitimate practice whichever of these you are sitting. That is why the set stands on its own here: the reasoning is the same reasoning, whatever paper it was originally written for.
