 Welcome to Unit 3 of Sailor.org's Spreadsheets course. In this unit, we'll build on what you've learned to make a practical, real-world spreadsheet of your very own. This unit will help to reinforce the steps you've learned so that you can apply your skills later on in a workplace setting. Good planning and wise use of formulas will help make your spreadsheet clear, flexible and effective. Experiment and don't be afraid. What you gain in professional ability and convenience will more than make up for the obstacles you might face along the way. It should take you about an hour to complete this unit. Good luck.
