What is an IQ Test?
An IQ test is designed to measure your relative intelligence compared to others. But what exactly does it mean to be intelligent? The concept of intelligence is not clearly defined, which means an IQ test simply assesses certain cognitive capabilities. Therefore, comparing different IQ tests is not feasible; only repeated tests of the same kind can indicate whether your performance is above average (above an IQ of 100) or below average (below an IQ of 100). Keep in mind that the IQ score should not be taken too seriously—use it as a way to gauge your performance against others! This application aims to assist in brain training as well.
Brain Enhancement and Training
To enhance your cognitive capabilities, we have incorporated multiple tasks and exercises into the IQ Test app that aim to improve your skills. Whether you're preparing for a job assessment or a psychological evaluation, you can utilize these resources to sharpen your mind and achieve better outcomes. The tasks transcend just IQ testing, offering help in logical reasoning, math, and more.
