If you were invited to participate in a coaching challenge you would have received a Coaching Activity Invitation email. Open this email and click the “View Activity” button at the bottom of the message.
Regardless of whether you are on a tablet, mobile phone, or laptop, you will be able to access your coaching account and participate in the challenge (Machine Analysis challenges cannot be completed from the Mobile Application at this time).
If your device has a web cam, you can record yourself from wherever you are to complete the challenge. You also have the option to upload an existing video – use this option if you have specific tools you prefer to use when recording.
For more information on how to complete a challenge, view this tutorial.
