Spanish Speaker Taking Spanish?

<p>I a fluent Spanish speaker and my high school requires you to take two years of foreign langangue regardless of ability. Because I was never taught how to read and write, I tested into Pre- AP Spanish 2 and will take Pre- AP Spanish 3 next year. I originally did not want to take AP Spanish 4, but I am starting to rethink it. Is it worth it to take AP Spanish 4 if I am already a fluent speaker?</p>
