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 taken Bio, Global, and Earth science and they were easier than the teachers made it seem.
The most pointless set of exams in the country. They're even worse more stupid than the SATs. And only in New York are they a requirement for graduation. 9 times out of 10, you don't need to even take the class to pass them.
I got a 90 on a practice biology regents before I even entered 9th grade.
