Past AP Essay Questions Organized By Topics

There are many AP Biology essay questions that teachers can use for test questions, homework, discussion points.  This file is organized by topic as much as possible.  Please remember that questions beginning 2000 were more likely designed with multiple topics across the curriculum rather than the single topic essay questions of old.  Hence, sometimes it was difficult to place a question within one topic.  This is a good thing!
