The flashmob made chicken noises, confusing others around them.
A New York State exam. There are Earth science, biology, and chemistry regents, math sequential A and B regents, english regents, F-Language regents, Global/American History regents, and God-knows-what-else regents.
I've takenBio, Global, and Earth science and they were easier than the teachers made it seem.
