Preparing for AP computer science A exam

<p>So I'm a sophomore this year taking AP compsci. I have a good grade in my class but all the things we've been doing in class are no where close to the rigor of the ap exam. I was just wondering if anyone who's taken this class before or is currently taking it has any strategies or tips for preparing for the exam particularly the free response section because I have no clue how to approach those. I'd really appreciate any help/ advice. :) </p>
