Although I have worked with excel a little in my past, I had no idea the things that excel could be used for. Without excel I am not sure how long some of those assignments would have taken me. Excel was a great tool that not only helped calculate the accurate data it also saved massive amounts of time. Excel is a key component in the business world so it is good that I worked with it so much. Some aspects of excel confused me at times but now that the course is over, I would say I am very comfortable with excel and will use it for future classes. My personal experience with excel is a positive one, I would have been a lot more lost without it. Our excel homework assignments really helped me focus on different skills within excel.
