Currently, a theory test is conducted using a computer which is equipped in a special keyboard adjusted to provide answers to theory test questions. In the past a theory test consisted of a number of tests in paper form where the candidates had to write correct answers using a pen. Today, because a special software is used, ale examination questions are mixed and every theory test is different. All questions appear at random. So you have to think logically. Some people say the current version is much more difficult because you could practically learn every test set by heard without thinking much about it. The examination starts with a trial version so the candidates have a chance to familiarize themselves with the rules and methods of providing answers and they also find out how the keyboard and the software work. Each question has three answers: A, B and C. As this is a multiple choice test, there many possibilities - only one answer can be correct, two or all three. Candidates have 25 minutes to do their theory test. After this time computers stops the examination and you are not allowed and not able to make any further changes.
