Would somebody please help me with AP Chemistry ASAP, PLEASE!

<p>Everybody please listen to me. This is my very first AP and its only about 7-10 days away. I am incredibly nervous. Now I read the princeton review, i took the 2 practice tests, i took the 84, 89, 94, 02 exams at home but i keep getting high 2's and low 3's. I would go over the mistakes of 84,89,94 and then take the 02 and 08 (in class) but i would still get a raw score of around 3. Maybe it is because I only answer the ones im totally sure about. Should i answer all of them for once to see how i do? I havn't even practiced the FR yet :( because i'm so hopped up on getting the mc right. I just wanna 4 or a 5, would somebody please help me. How can i improve? Any online websites that teach exactly to the ap exam. I am also looking desperately for the 2008 exam at home (online) because it would probably be most similar but I can't find it :'(. I did find the 08 practice if anyone wants it. I havn't really done that yet so should i? but i don't wanna fail it again :(.</p>
