Free test, stronger coverage
Twenty calibrated items are sampled from a 300-item bank and balanced across pattern, quantitative, verbal, spatial, and formal logic reasoning.
Online IQ-style scoring
Results use item difficulty, guessing correction, response time, completion quality, and score interval reporting.
Useful score context
The report highlights rushed attempts, incomplete coverage, and domain imbalance before interpreting the score.
