Error while taking practice theory test

Sometimes when we are part of a group or we participate in an even that is interesting to us we are only focused on the main goal, forgetting that we are able to get something more from this situation. What do I mean? It can be clearly seen at the example of school. The main goal of going to school is to get some knowledge and finish it. But at the same time we are able to do things that are not strictly connected with it. For example, we can meet very interesting people that might be our friends for life. We can also attend additional classes that allow us to expand our hobbies, passions, etc. There is always a possibility of getting something ?extra" in each of this situations. That formula applies as well to driving course. Instead of only listening to lectures and making some exercises we are also able to do something else. Most of the people are not aware of the fact that there is a possibility of taking practice theory test after standard classes. You are able to stay a bit longer and try your luck with passing practice theory test on the computer. It looks exactly the same as if it was a real examination. Recently when I was doing such test, there was an error as something was wrong with the computer. I thought that if something like this would have happened on the real exam that would be a disaster. Luckily it was just a practice theory test.
