In Finance 4335, students are welcome to rely on either Excel or hand-held calculators to calculate answers for problems that appear in problem sets. However, in order to earn credit, students must show their work by providing logical explanations of how they get their answers, using properly formed English grammar, along with references to the appropriate theoretical concepts. The best examples I can think of how to “show work” appear in most of the various linked PDF documents comprising solutions for class problems, problem sets, and sample exams @ http://risk.garven.com/category/problem-set-solutions/.
Keeping this policy in mind, do not upload Excel spreadsheets to Canvas when you turn in your problem set assignments. I base your grades solely on how well you explain and support the answers you provide in the PDF documents which you upload to Canvas.
