Amazingly (to me and, probably, to my eighth-grade science teacher) I did pass this little quiz; see my badge of honor below. The questions cover a range of content from photosynthesis to physics. And you can review the answer sheet at the conclusion of the "exam."
What's most interesting is that this is not a science-related site, but rather an Internet dating service called Just Say Hi. Not sure what an online dating site and science quizzes have in common. They have several other online quizzes, too (How Addicted to Coffee Are You? and The Germ Quiz -- How Many Germs Are There On Your Keyboard may also be worth a click.)
A fun diversion, anyway, amidst the heightened focus on math and science these days.
