In Finance 4335, students may use either Excel or hand-held calculators to calculate answers for problems that appear in problem sets and exams. 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, coupled 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 consisting of solutions for class problems, problem sets, and sample exams @ http://risk.garven.com/?s=solutions.
Keeping this calculator policy in mind, do not upload Excel spreadsheets to Canvas related to exams and problem sets. Your grades are based solely on how well you explain and support the answers you provide in the PDF documents which you upload to Canvas.
