Who is not afraid of tests?
When I was a school kid (and not a very good one, mind you), I hated tests. I used to be so scared I was sick on the day. Sometimes, this worked and I got to stay at home, but most of the times I still had to go to school and take the test. The more I was afraid of tests, the worse my grades were. You could say that the worse I thought I would do, the more I feared the test.
