How long has it been since you graduated from high school? Do you remember how to use a protractor? Do you know what the synovial membrane is? Who preceded Winston Churchill as prime minister? When did the Civil War end? By the time students reach that monumental "senior" year, they are in command of a lot of knowledge. They study core subjects like math and English but also take many elective courses that range from art to accounting. Do you think you have what it takes to compete with their knowledge base? Over time, many of us forget what we learned in high school. Why not take our test to determine if you can pass 12th grade all over again. Show off your smarts and dazzle us with your wits! We’ve created a 12th-grade test that covers all the subjects seniors are likely to study. Put on your thinking cap and begin!
