A cognitive abilities test is a test that measures how you think. It looks at all the different ways you use your brain when you solve problems and make decisions. The test looks at things like your memory, attention span, ability to learn new things and understand new concepts, and how quickly you can think and process information. There are different tests for different ages, so some tests are more challenging than others. The test usually takes around an hour and you get a score based on how well you did.
