Quiz 4

Quizzes are short assignments due after each lecture that allow you to apply each week’s concepts to new problems. Each quiz is open-book: you may use any and all non-human resources during a quiz, but the only humans to whom you may turn for help or from whom you may receive help are the course’s heads.
