Want to test out your grammar knowledge? The New York Times recently published this series of short, interactive quizzes that allow readers to take a stab at copy editing sentences from recently published articles. Each quiz features about a dozen sentences taken from actual Times articles. Readers are then tasked with identifying the word that needs editing. When they select the correct word, readers can see how well they did in comparison to other quiz-takers. This interactive activity may especially appeal to instructors of upper-level writing classes. As of this write-up, the series includes nine quizzes. By following the link above, readers can check out the most recent quiz and find a link to previously published quizzes.
