To complete a course, you need to do the following:
Take each of the 4 end of module quizzes (You can take these as many times as you like.)
Take the final exam, and pass with 70%+ correct answers. (You can have 3 attempts at this, if you need to.)
All other activities are optional. However, each activity is designed to help you to put your newly acquired knowledge into practice.
We therefore recommend that you complete these activities too, to get the most out of your training.
