In 1974, this general knowledge test was given to a group of 250 American high school students. Most of them did not get better than 15 questions correct on this test, which mixes easy and hard questions and varies on topics such as Geography, mythology, history, and hard sciences. Now, 45 years later, this test holds up remarkably well, and I wonder how well high schoolers would do. Since we don't have them around, how about you? Put your knowledge to a literal test, and see if you can beat the original group's average.
