In honor of our Independence Day, Time has developed a fun, interactive quiz to determine how well you know the map of the United States. The quiz asks you to draw each state one at a time, and then will update the map with your version as you go along. As more people complete the task, they will compare all participants and give out some fun data.
The process: "Once you’re finished sketching the outline with your mouse or finger, we’ll compare your version to the actual boundaries and give you a letter grade as feedback. The algorithm that we wrote to compare your shape to the actual one is forgiving of differences in minor undulations of the borders, so you only need to focus on drawing the overall contours of the state. Grades are slightly curved to be more lenient on highly complex borders."
Take the quiz here. Good luck!
