AP Chinese Exam Difficulty for Non-native Speakers?

<p>Hey so I'm taking the AP Chinese Exam this year and I have the Barron's AP Chinese Prep book. Does anyone know if the questions in Barron's will be as difficult as the ones on the exam because I found a good portion of the questions to be sort of difficult, and I'm a heritage speaker. I can speak speak and understand intermediate Chinese I would say, but I really want to do well and I'm afraid of the cultural and writing section more. If anyone's previously taken the exam could tell me how difficult it was I would be really grateful. </p>
