Each quiz and the final exam questions come from question banks that are three times the size of the quiz or exam. For every question asked there are three available questions in the bank. Each quiz randomly chooses questions from the bank. You may see some repetition of questions, or questions of a similar nature, but each time you take a quiz, it will be different from the previous attempt.
You have as many tries on the quizzes in each course as you need. No one will see your quiz results so don’t worry if it takes you a couple of tries.
Course final exams may have a limited number of attempts. For more information about course final exams, click here.
