Thus, always document all help that you receive. Documentation consists in specifying from whom the help was received, the extent of the joint effort, and the depth of the help. In some cases you will work as a member of a group and the group will submit its work for a single grade. In these cases, help received and material generated within the group does not have to be documented. However, sources outside the group must be documented.
Documentation is required for all graded homework.
However, if the homework assignment does not specify that this assignment will be graded, even if your instructor later grades it, then documentation is not required. This allows us to distinguish between someone who didn't require documentation and someone who forgot to document. List by title and author all reference materials used in accomplishing the assignment. You need not document your course text and assignment sheet. In rare circumstances, you may wish to quote a statement made by others.
