Original IQ-Style Reasoning Test
Work through 25 original problems across five reasoning domains. Your result includes a transparent practice score, section breakdown, and an explanation for every item.
Balanced coverage
Five questions in each reasoning domain
Difficulty rises within each domain, so the result is less dependent on a single type of puzzle.
Pattern Reasoning
Detect rules that govern sequences, pairs, and matrices.
Quantitative Reasoning
Solve numerical relationships and practical math problems.
Logical Deduction
Identify conclusions that must follow from stated rules.
Verbal Reasoning
Work with meaning, analogy, and precise language.
Spatial Reasoning
Mentally rotate, reflect, and track objects in space.
What your result means
The score is the percentage of these questions you answer correctly. It helps compare your own performance across the five sections and review missed items.
Important limitation
This is an educational IQ-style practice test, not a standardized or professionally administered intelligence test. It has not been normed on a representative population, so it does not produce a clinical IQ score, diagnosis, percentile rank, or eligibility decision.
All questions on this form were written for Cognitive Index and are not third-party assessment items.
