Be sure that all your work is really your own. When you're writing papers, taking tests, writing code and submitting any assignments, be careful to claim only what is your own personal work.
Attribution
Whenever you quote someone or base your ideas on another person’s work, you must document the original source that you used. If you are unsure what is allowed in your course, refer to the syllabus and ask the instructor. This counts for homework assignments, research papers, exams, and individual/group projects.
