The high-ceiling culture-fair IQ test is similar to our culture-fair IQ test in that it's primarily designed to test IQ while minimizing cultural and educational biases. The main difference is the difficulty level. The questions are much harder and rely on more spatial ability to solve them than our standard culture-fair test. Like the previous one, this test relies on pictures and images rather than on words and assesses your spatial abilities. The concept of spatial ability consists of several components such as mental rotation, spatial perception, and spatial visualization.
