Self-studying both AP Spanish Exams for a Non-native Speaker

<p>Today I decided that I am going to self-study both AP Spanish exams, Literature and Language, for May 2015. I am a high school junior right now and this year I am overwhelmed with AP classes, but I'll have a much lesser workload during my senior year, so things will be a lot less hectic. Just to give some background with languages:
9th grade, I thought that my Spanish class would actually teach us to speak the language. Boy was I wrong. I bought an Assimil course (they're amazing, by the way, and I absolutely recommend them) for Spanish. Using the Spanish one first, I learned enough to merit myself a lower-intermediate level by the middle my sophomore year. I was advanced enough that my Spanish II teacher asked me over and over again if I was bored in class, and I said that I was, so I was switched to Spanish III in the middle of the year, where my teacher was absolutely amazing--he used absolutely no textbooks and taught us through TPR storytelling. That was when I gained knowledge of Spanish rapidly, and that continued through the summer. At this point, I can hold a conversation about general topics pretty well and I can understand almost everything (that I've read so far) on BBC Mundo, and I can get through high school-level novels with some difficulty. </p>

<p>Knowing this, how hard would a self-study be? I'm in AP English Literature right now, and it seems to me like the Spanish Literature test is almost the exact same thing, just in Spanish, while the Language test seems a lot more varied and less specialized. For those of you who have self-studied/are taking the class, what books are you using, and which would you recommend for me? I am also trying to come up with a curriculum for myself to follow, so anything will help. Thanks in advance.</p>
