The test is divided into two subtests, each of which lasts about 45–60 minutes. The first part (Basic Skills I) tests basic skills and consists of 22 questions, and in the second part (Basic Skills II) you complete 14 questions to check your higher-level math skills. You can choose the order and the times when you want to complete the tests. However, before you can start the first test, you have to complete a short preparatory section (consisting of four tasks). These serve to show you how to enter mathematical expressions.
