If a student knows how to communicate, they can solve this problem: warn the teacher, take a sick leave if they feel they are not ready, and other options.

If they did not do this, they failed the exam on communication with other people.

In addition, we are not always able to make decisions in ideal conditions. We need to learn how to solve problems under pressure, in emotional turmoil, and when we are not feeling well.
