AP U.S Government & Politics

This is my very first AP Class I took in my entire life and I am willing to take the test to receive the college credits for my future college. I got a C in the class because it was really hard to understand the english language as a foreign student. My main language is Spanish, but I am also know how to speak Arabic and English. My English is my 3rd language and I know it more than my Arabic. During my quizzes, I found it really hard because it feels like I am taking the SAT and everything is not really straight foward or self explanatory. So now, I want to challenge myself and try to get a score of 3-5 in this test, but I do not know how can I prepare myself or what is the test going to be like because I never took an AP Test and Class before. Anyone can help me please?
