People taking exams sometimes have some or all of the following symptoms.
 
* A growing feeling of impending doom in the days and weeks leading up to the test or exam.

* Dryness of the mouth, upset stomach, tension headaches, insomnia, etc.
 
* Their voice quivering and weak in a spoken exam.
 
* Unable to write, type or do other manual tasks because their hands are shaking so much.

* Staring at an exam paper... and not being able to think of a single answer!
