Reading this result
The margin of error is theoretical: it assumes the difficulty of each question is exact, which the test's calibration has yet to confirm. The score is most reliable on the first attempt.
This test estimates logical reasoning. For a diagnosis (giftedness, learning difficulties), see a psychologist.

Your path
Each dot is a question, from easiest (left) to hardest (right). The blue line shows your estimated level: in general, people get right what is below it and get stuck on what is above it.
Your reasoning map
The questions rely on different types of rules. Here are the ones you found easily, and the ones that gave you trouble.
A question can combine several rules: it then counts in each of them. With 1 to 5 questions per type, this map describes today's test; it is not a diagnosis.
The answer key, question by question
Open a question to see your answer, the correct answer, the rule to find and the time you spent on it. Good to know: if you retake the test, matrices you have already seen will not be shown again as long as there are others left at an equivalent level.
