Start the Online Test — FreeAccessibility and convenience
Online IQ tests are accessible from any device with an internet connection — no need to schedule an appointment with a psychologist, travel to a testing centre or pay hundreds of pounds for professional assessment. Online testing democratises cognitive assessment, making it available to anyone curious about their reasoning ability. This test provides a reliable snapshot of your core cognitive ability in the format and on the timeline that suits you.
This online assessment measures the same cognitive dimensions as professional IQ tests — reasoning, pattern recognition, problem-solving and verbal/numerical ability. The key difference is accessibility: professional tests are more comprehensive, more precisely normed and clinically valid; online tests are faster, free and suitable for educational self-assessment.

Reliability and validity of online testing
Research shows that online cognitive tests, when well-designed, correlate strongly with professionally-administered tests (typically r > 0.85). However, online tests have broader confidence intervals — meaning while they give useful information about your general ability level, they are less precise about your exact score. Online tests are also subject to environmental factors (distraction, fatigue, motivation) that professional tests control for. For curiosity, self-assessment and general ability screening, online tests are reliable and valid. For clinical diagnosis, educational placement decisions or other high-stakes purposes, professional assessment is essential.
This 30-question online test measures three core dimensions of general cognitive ability (g factor). These dimensions predict academic performance, professional outcomes and learning capacity more reliably than any single cognitive metric.
Abstract Reasoning
Identifying patterns, sequences and relationships in abstract visual and conceptual information independent of prior knowledge.
Numerical Reasoning
Understanding numerical relationships, performing calculations mentally and reasoning about quantitative patterns and probability.
Verbal Reasoning
Comprehending language, identifying logical relationships between concepts and evaluating deductive and inductive arguments.
Answer each question carefully. No time limit — work at your own pace, though most people complete this in 10–15 minutes. Your score will be calculated immediately after completion.
