You can find all modules on your homepage. Work through them one at a time to complete your Day 0 training.
Make sure you complete your training before Day 1. You won't need to complete the training all at once. Your progress will be saved if you exit the course.
You will earn badges as you progress through the course, each one building up your Amazon toolkit.
Once you have completed all modules, you will be ready to move forward on your Amazon journey.
