Same here. I always get nervous to the point where I make the dumbest mistakes on tests, mistakes that when you get the test back and look through it, you see exactly what you did wrong and you wonder why you wrote/chose the wrong one instead since the right answer was so obvious. Some people just happen to be very nervous test writers. I know for a fact if I wasn't like that I would have an appriximate 97 overall average, but well, because of those ridiculous mistakes my average is usually around 87.
I just can't believe how ignorant some people can be though. They truly believe that if a person gets a higher mark on a test, for example, that means that that person is automatically smarter. What they fail to see is that there are alot of people out there who spend hours day and night, every waking moment, studying, studying, studying, memorizing every single word of a textbook, regurgitate everything that the teacher/prof says. But does that make them intelligent?
Sorry, it just really gets to me sometimes.
