Aptitude tests usually include questions that relate to logical and verbal reasoning, analysis and recognition of patterns, figures and numbers, and error recognition and correction capabilities of the candidates. These tests come in different formats and can also have different structures. There are for instance adaptive tests that adapt to the candidate’s level of intelligence during the test. Aptitude tests are usually strictly timed and correctly answering as many questions as possible is key to success. To pass these tests, regular and intensive practice is a necessity.
