Why don't/do you like taking tests

Why do I don't/do like about taking test. Well lets start why I like taking tests, their fun boring and take a lot of time, what isn't there to like? You see I like to take test so I can show my knowledge of the subject. Plus in most classes you can take all the time you need to take the test. When you are not finish with the test what you could do is to study more for whatever is on the test. You could easily have looked through the test to find out what you'll be tested on next time you come to class. Pure genius. 

Now on to the bad things with taking a test. It is long and boring, why? Because sub-consciously the mind is thinking "oh no! I have no idea what to do so I shouldn't care, but I should if I want to pass whatever this class is." So the mind would slow everything down to gather as much information of whatever subject as possible. Making the test seem boring and taking a lot of time because it is taking a lot of time and nothing else is happening. I could be wrong with this but it does sound plausible, who knows maybe its because you don't like the school system and want to rebel against it, or you could have a crapy day or someone could have farted. What ever the cause may be we'll find away to make it boring or time consuming and waste time.
