Seminar Rules and Structure Usual format of seminar will involve a brief discussion of a concept and then working with the Excel template for that unit. You should try very hard to download and examine the template before seminar. We will be working with Excel during the seminar and you will need to have it up and ready. Since it is an audio seminar you can be actually working in Excel as I talk you through the procedure. You do not need to post unnecessarily but I would like to know that you are working the problem and whether you are having success or trouble with the procedure. Social posts (It is raining, Hi, Bye, My car broke down) will not help your participation grade.
