Hey english honors student stepping in:

Hey, that thing is easy. I got a 4. Just study hard, and make sure you read the questions carefully and answer your best. It's not scary, it's a piece of paper. If you don't worry about it, it will come easier, rather than you getting so scared on how you will do. That is what happens to me on my playing tests. Of course I cannot speak for you, so you may have different ways of thinking about this stuff. Don't worry, really, it's not that bad. Just make sure you study, and you'll do perfectly. If there is no way to study(I remember studying for mine though), then practice your essay-writing skills. Is there any way you can ask your teacher for some help in your spare time(lunch for example) or for her to arrange an extra help session for people? My teachers do that all the time, I find it quite helpful. Even though they cannot tell you what is on the quiz, they can help you get prepared to look that test in the eye and say "I'm ready".
Sorry if I sound crabby, I'm really not... Good luck!
