Submit HW through the Learning Management System (LMS) - say, Blackboard or BrightSpace. Do not email HW
Combine all relevant files (e.g., images, MS Excel, ...) into a single PDF file.
As far as possible, document in the files themselves - your name, Assignment name, description, etc.
Every assignment requires a narrative, which should appear at the front of the PDF package. In this narrative, include such items as: the objective of the assignment; how you solved it; results; conclusions, what you learned; the overall experience; challenges that arose.
