Understanding These Sample IQ Test Questions

First and foremost, IQtestprep.com’s IQ tests are for entertainment purposes only. While our IQ questions and answers have been developed and refined to test real aspects of intelligence similarly to popular cognitive abilities tests, they are not as comprehensive as official intelligence tests. You’ll need to contact a local testing center, psychologist or Mensa chapter to take a proper IQ test that would be used in a professional evaluation or to gain entrance into a high IQ society like Mensa which requires a verified IQ in the 98th percentile.

Genuine IQ Test Sample Questions

While the IQtestprep.com practice tests focus highly on information processing, most modern tests focus on a wider variety of aspects of intelligence. In formulating an IQ score, the popular Wechsler tests focus on the following indices:

  • Verbal Comprehension Index
  • Perceptual Reasoning Index
  • Working Memory Index
  • Processing Speed Index

There are subtests within each of these indexes where the IQ test proctor will provide questions and when you answer correctly your score for that subtest will improve and increase your index score for that component of your intelligence. A selection of these subtests is then combined upon the test’s completion to make up your Full-Scale IQ, or FSIQ. Average intelligence would be someone with an FSIQ score of 100.

Sample Similarities Subtest Question

An example question from this type of IQ test would be within the similarities subtest in the Verbal Comprehension Index. In this test, the proctor will provide you with two items, so for example, “milk” and “orange juice”. The subject is asked to provide information as to what the items have in common. A highly specific such as, “They’re both beverages” would be worth two points while a less specific answer such as, “They’re both liquids” would be worth one point. These questions will be presented in a series, and you will either receive partial or full points for each correct answer, or you will be cut off after too many incorrect responses and you will proceed to the next section of the test.
