Re: Difficulty levels

5. IMHO, the object comes from the repository w/o the level of difficulty that should be assign by author, or is considered as having lowest possible level.

6. IMHO, author should assign an object to a group of students (filtered or selected from the list). It's also possible to assign a group of objects (filtered or selected from the list) to a student or a group of students

Perhaps questions below should be answered too:

5. What happens when author adds object to his course from the Repository?
   Is difficulty level of that object stays the same or will be determined
   by current author?

6. Will teacher be able to assign his course objects to students by level of
