Help with AP US History?

Please, only serious answers. This year, as a Sophomore, I took AP US History. I've been a rather good and successful student throughout the year. I can average a good, solid 4 on practice exams. I tend to get around 75% correct on the multiple choice, and I've never gotten an essay or DBQ back with a grade lower than a 6, with a rather hard essay grader for an instructor. But, now I'm beginning to psyche myself out, so to speak. I walked into the classroom on Monday to see it totally decorated with all of the posters and visuals we've made throughout the year, not one area was not covered. Just seeing all of the topics, and people, and events, etc., makes me think... What if they have that one category that I don't do so well on, and make it a large portion of the test? All I think I really need now is a pep talk... So, anyone willing to help a 16 year old feel better about the huge test next Friday? :)
