AP World Nerves

<p>So i'm studying with the "5 steps to a 5 world history " book and i've taken the practice tests in the book and man are those questions tough. I've had a great teacher this year and an A/B average but i'm not sure i'll get a 5 on my exam. I've got the DBQ down and that's about it. I feel like when i get to the CCOT or CC i'll freeze up because it will be on something i have no knowledge of. Any advice from an ap student freaking out here?</p>
