Did you provide support for all your answers – diagrams, tables, calculations …?
Quick comment on the case study. Please make sure that you include your support on how you solve the problems in your Word document that you submit. Show your work! Show the equation that you used to do the calculations. Show one calculation fully worked out. Use Excel to create your tables for the document. Use powerpoint to create your graphics (AoAs or AoNs). Cut and paste them into your Word document. NEVER just put an answer. We also grade you on the PROCESS. No process (also known as showing your work), you will lose a lot of points on your case study. Show the process and make an algebra error … that is a minor deduction.
