Difficulties of a theory test
Like with almost every test in life, there may occur some difficulties with a theory test. They may vary depending on the situation but generally we might divide them into two separate groups. First is concerned with the fact that the test is based on computers. Like every computer, those that are used to provide theory test, might broke. It even happened during my exam. Fortunately not with my computer but a woman sitting next to me. Everyone was focused on their test while suddenly we heard a loud beep sound and her computer crashed. She was lucky though, because the staff has repaired her computer immediately. But technical problems are not the only problems. Another factor that might cause the problem are the people who are answering the questions. If they are not familiar with a free theory test, they might press the wrong button and finish their examination before answering all the questions. You have to know, as well, how to go back to previous questions. I hope you won't encounter any problems during your test.
