How this data is usedHelp
At Easy and Standard, options contain the same collection of plotted values. Match each value to its group and convert the indicated units. At Challenge, X and Y make up each group. Divide each count by that group’s own total to find its percentage. Every option totals 100% per group, so check the denominator and the labels. All bars start at zero and print their exact values. Filled and outlined bars distinguish series without relying on color. These are original reasoning exercises, not an intelligence assessment.
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 and Enter or Space to choose an answer. The number keys also select answers, except when another control is focused. After an answer, Enter goes to the next question.
Original practice puzzles, not a standardized assessment.
