I don't have access to real-time information, including the specifics of how students felt about a particular AP exam administration. To find out how students generally felt about a *specific* AP Comparative Government exam, you would need to search online for student reviews and discussions on forums like Reddit (r/APStudents, for example), College Confidential, or other online communities where AP students share their experiences.
Keep in mind that opinions will vary greatly depending on student preparation, individual strengths and weaknesses, and the specific questions asked on the exam. There's no single answer to "how was the exam?".
