INTEGRITY: It is OK (and indeed encouraged) to discuss homework assignments with fellow students.
However, any and all submitted work must be your own.
Merely copying someone else's work is unethical, a waste of time, and may be penalized.
(This includes copying solutions found on the internet.)
Any substantive collaboration and/or usage of sources or AI tools has to be properly acknowledged.
See CWRU academic integrity policy.
