IQ Test

The IQ Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests IQ-style general reasoning across four kinds of item used in cognitive ability tests — number and letter series, verbal analogies and vocabulary, logical deduction, and abstract and spatial patterns — under time pressure. Score 70% or more on its 20 questions to earn a verifiable Cognitive Ability (IQ-Style Reasoning) certificate (SOA-IQ). Every question is based on published standards and research — including International Cognitive Ability Resource (ICAR) (ICAR Project), Psychology 2e (OpenStax (Rice University)), English grammar reference (Purdue OWL) — and each answer is explained with its source.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Cognitive Ability (IQ-Style Reasoning) certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: International Cognitive Ability Resource (ICAR) (ICAR Project); Psychology 2e (OpenStax (Rice University)); English grammar reference (Purdue OWL); Cognitive Reflection and Decision Making (Frederick, 2005) (Journal of Economic Perspectives); Prealgebra 2e (OpenStax). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Number and Letter Series (Arithmetic sequences, Multiplicative patterns and Letter patterns); Verbal Reasoning (Analogies, Vocabulary and Odd one out); Logical Deduction (Syllogisms, Conditional reasoning and Ordering and quantities); Abstract and Spatial Patterns (Shape sequences, Rotation and reflection and 3D reasoning). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

Job seeker, Student, Graduate applicant, Puzzle enthusiast and Career switcher. It suits anyone who wants a quick, verifiable way to show IQ skills, from students and career switchers to experienced professionals.

Yes. The IQ Test is free and covers all of these: 20 scenario questions in 20 minutes, each answer explained with the source it comes from, so it works as interview and exam practice. It isn't a full course, so use the areas you miss as your study list. Scoring 70% or more earns a verifiable certificate.

No. This is a reasoning test in the style of cognitive ability assessments, scored by the share of questions you answer correctly. A clinical IQ score needs a standardised, professionally administered test such as those used by psychologists. Use this to practise and to show reasoning skill, not as a diagnosis.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
