Under the Honor Code at Stanford, you are each expected to submit your own work in this course. On many occasions, however, it is useful to work with other students or to ask for general advice from the course staff or other experts. Such activity is both acceptable and encouraged, but you must indicate any collaboration or assistance on your solution sets. Any collaboration or assistance that is not given proper citation may be considered a violation of the Honor Code. Furthermore, study groups should be limited to three students. In any event, you are responsible for understanding and being able to explain the solutions you submit. The course staff will pursue aggressively any suspected cases of Honor Code violations.
