You thought you could sign up for AP GOPO without doing essays? Haha, you're really funny. Essays take up a huge percentage of your grade, so learn how to be a better writer now, you'll thank yourself later. There's always an essay on each unit exam, but it's over stuff you have covered. Besides the unit exam essays, we have one for each semester, and possibly one on your finals. Try to keep every major thing fresh on your mind when the AP Exam is creeping up, you never know what four essays they will choose as topics.
