Instructions

M1A2-Quiz module 1 is a 25 question multiple choice quiz. There are a total of 100 points possible.

Please choose the best answer that is listed. Each question is worth 4 points. You will have 45 minutes to complete the quiz. Once you open the quiz, you must complete. You will not be able to reopen the quiz if the time has elapsed.

You will be evaluated based on your responses to the quiz questions. Collectively, quizzes are worth 15% of your final grade.
