Mensa.org offers one timed, 30-question practice quiz, the Mensa Workout. Types of quiz questions include unscrambling letters to form a word, interpreting sayings, identifying patterns in a sequence, logic problems and math problems. Quiz takers can see their score and the correct answers for each question at the end.
The practice quiz is not an IQ test and does not qualify a person for Mensa membership. Scoring does not give an equivalent IQ score. US.Mensa.org also offers a 30-minute practice test that requires purchase of a test key and that provides an equivalent IQ score for the test score.
Other websites that offer Mensa practice tests as of November 2015 include Archive.RJG.com, Pleacher.com and Lifesmith.com.
