But what is intelligence? This is not a defined term and so intelligence is just what an IQ test measures. Therefore, different IQ tests can not be compared, just the same test, and it simply tells you if you have solved the tasks better (over IQ 100) or worse (under IQ 100) than the average. So do not take the IQ that seriously, just test how you cut off compared to others! This app is also developed for brain training. --------------------------------------------------------------- Brain booster and brain training --------------------------------------------------------------- To improve your brain performance, we have added numerous tasks and exercises in the IQ Test app that will increase your performance. So if you are about to take an employment test or a psychological test, you can use it to train your brain and get a better result. The tasks are not only in the IQ test area, but also help to improve logical thinking, math and more. --------------------------------------------------------------- Information about in-app purchases and subscriptions --------------------------------------------------------------- There is a Pro subscription in the app. The following notes apply: - The Pro Subscription offers you additional IQ Test functions such as explanations, further tests, numerous exercises and much more. - The Pro subscription is valid for 1 month and will be automatically extended for this period if you do not cancel 24 hours before the end of the period.

About

calYc

Read full description

calYc uses the four basic arithmetic operations and defined number ranges to set arithmetic problems. The level of difficulty is determined by selectable symbols (hatching chick, standing chick, etc.). If a selected symbol is chosen again, further application-related information (e.g., number ranges) and settings (e.g., time, sounds, multiplication tables) become available. If the time measurement is set, a maximum of 20 seconds is added for solutions at the most difficult level and a maximum of 10 seconds for solutions at other levels.
