Headaches of Tests

You know when you study and study and study and endlessly study for an upcoming exam and by the end of it you feel like you have everything down?  Your friends can quiz you on certain theories, words, philosophies within the unit and you can answer them like you're giving off your first name.  Then when the day of taking your exam comes you get in there with your highest confidence ever met and you sit down, wait for that test to come to you and once it does you open the first page and then.... then... well then you realize you don't know jack.  Isn't that so funny?  Then you do the best you can and after you turn it in and leave you're just thinking what the hell?  I just bombed that test.  Does it make sense?  Nope.  But you have another exam next Thursday, so you have to get over it and hope it doesn't happen to you again.
