The College of Engineering honor code applies to all exams. See
http://www.engin.umich.edu/org/ehc/index.html .
Concerning collaboration:
All homework assignments are to be completed on your own. You are allowed to consult with other students during the conceptualization of a solution, but all written work, whether in scrap or final form, is to be generated by you working alone. Violation of this policy is an honor code violation. If you have questions about this policy, please do not hesitate to contact an instructor.
The same policy applies to lab assignments, except of course, that lab partners are permitted to work jointly in all respects. Note that programs written by one lab group are not to be shared with other groups.
