This test is originally from Japan, where it's named 精神年齢チェック. Please answer every question honestly. Nobody will see your answers.
The result has nothing to do with your Intelligence Quotient. For the purpose of this test, we define Mental Age as a measure of a person's psychological abilities in comparison to the number of years it takes for an average child to reach the same level. For example, if your mental age is 10, regardless of your actual chronological age, you are mentally similar to a 10-year-old.
