The longest course is about 3 hours and some of the shorter courses are 20 minutes or less. I recommend diving in as you need—spending more time upfront and then coming back as you need to like a library.  PRO TIP: Make sure to complete the corresponding workbook assignments as you work through the course modules. They really make this experience so much more tailored to YOU. If you’re worried about having the time to work through the content, know that this course never expires! You can learn at your own pace from the comfort of your own home. You’ll have lifetime access to all of the course materials, and you can rewatch them, replay them, and enjoy them as often as you’d like.
