About the NimbusCalc IQ Test
Our IQ test is based on modern psychometric principles and measures fluid intelligence – your ability to solve novel problems, recognize patterns, and reason logically. The test includes questions from four cognitive domains:
- Logical Reasoning – deduction, analogies, pattern recognition
- Mathematical Ability – numerical sequences, arithmetic, quantitative thinking
- Spatial Visualization – mental rotation, shape completion, spatial relations
- Verbal Comprehension – vocabulary, analogies, verbal logic
Your raw score is converted to a standardized IQ score with a mean of 100 and standard deviation of 15, based on a large normative sample. The result includes your IQ, percentile rank, and a classification from "Very Low" to "Superior".
Premium users receive a full breakdown of their performance in each domain, personalized improvement recommendations, and unlimited test retakes.
