Every question in the question bank belongs to a category. If a question belongs to a category for the course, only teachers with access to that course can see and reuse the question. If a question belongs to a category for the system, the question can be seen and reused by all teachers in the system. To let your questions be used by other teachers, you might want to move them to a category that is accessible by other teachers.
Select the question(s) to move, select the category, and then click on the Move to button.
