A new create and edit experience for Quizzes occurred in the June 2022 release of Brightspace (20.22.6). The goal is to simplify common tasks for first-time or infrequent users, while giving easy access to the advanced features that our experienced power-users love. Bringing consistency to how activities in Brightspace are created helps achieve this goal.
