Personally, I think it's good practice not to worry about others and tests and test takers other than myself.  It is a short cut and gives me more time to think and process. 

Are you thinking about "test anxiety" where one becomes so anxious at the advent of an examination that they just perform tragically?And do you mean ignorance or stupidity?   In any case here's some information about "test anxiety">>>

What Is Test Anxiety?
Test anxiety is actually a type of performance anxiety — a feeling someone might have in a situation where performance really counts or when the pressure's on to do well. For example, a person might experience performance anxiety when he or she is about to try out for the school play, sing a solo on stage, get into position at the pitcher's mound, step onto the platform in a diving meet, or go into an important interview.

Like other situations in which a person might feel performance anxiety, test anxiety can bring on "butterflies," a stomachache, or a tension headache. Some people might feel shaky, sweaty, or feel their heart beating quickly as they wait for the test to be given out. A student with really strong test anxiety may even feel like he or she might pass out or throw up.

Test anxiety is not the same as doing poorly on a certain test because your mind is on something else. Most people know that having other things on their minds — such as a breakup or the death of someone close — can also interfere with their concentration and prevent them from doing their best on a test.   READ MORE HERE>>>http://kidshealth.org/teen/school_jobs/school/test_anxiety.html
