If you have been locked out of your course and cannot move on, it’s most likely because you have scored too low on a test.

Each teacher sets a threshold for the minimum percent you can get on a quiz or test and still move on through the course. If your score falls below that, the course becomes locked. All you need to do is notify the teacher of the course that you need a quiz reset and they can unlock that quiz so you can have more attempts to get a satisfactory grade. It’s helpful any time you are emailing a teacher to tell them your full name and what course and quiz you are referring to.
