How can test anxiety influence a student's test score?

Test anxiety influences a student's score depending on really how bad it is. A lot, a student may second guess themselves on answers, frequently getting them wrong due to anxiety. When taking a test, you need to look at it like this; no matter what score you got, you tried your best, and even if your score is bad, just study study study and you can get an even better score on the next test.

When I took tests, I flunked them due to Anxiety, yet my class work were always A's. It'll kill your test scores.
