Pre-test

Before you begin this course, test your skills by taking the following assessment to see where you stand. Keep track of your incorrect answers to know which skills you should study. You'll have a chance to take this same practice test again at the end of the course to see how you've improved.

All questions must be answered to submit your assessment.
