StudyBuddy now runs on a new platform, and this older site has been retired. The link you followed no longer works.
To get into your course, go back to your course in D2L and open the StudyBuddy access link your instructor posted there. It will take you to the right place and you'll use the same access code as before.
Can't find the link, or it still isn't working? Email support@studybuddy.live with your course name and we'll send you the correct link.
