How to play

Check the labels and units first. For a percentage increase, compare the increase with the starting value. For a share, compare one value with the total of all four. All data is fictional.

Each round has six questions and no time limit. Choosing an answer locks it. Review the steps, then move to the next question. Finish all six to save the round. Active time includes reviewing the steps, but does not count time when this page is hidden. Speed does not affect your score.

Use Tab to reach a control, then Enter or Space to choose it.

Original practice puzzles, not a standardized assessment.
