RACHEL MARTIN, HOST:
Good morning. I'm Rachel Martin. History, policy, American institutions - all topics you might expect on the AP U.S. Government and Politics exam. One you might not anticipate - a free response question about Taylor Swift. CNN reports that the surprise prompt put a smile on some students' faces. And hey, even if they didn't score well, they could always just, you know, shake it off.
TAYLOR SWIFT: (Singing) Baby, I'm just gonna shake, shake, shake, shake, shake - shake it off, shake it off.
