The Certificate program consists of 3 stages, for a total of 19 modules. Most modules will take 1-1.5 hr to complete. The quizzes should only take 5-10 minutes to finish. If you were to take the Certificate course all at once, you could finish this within a week. However, you have up to 12 months to complete the certificate, which is useful if you are working or studying full-time.
