Excel is an amazing tool that can do the majority of the math for this class. Have you used it before? What have you found to help you out with Excel? Is there a youtube video that has been helpful? Is there a website or book (paper is the worst). What are you using to help either refresh your memory on Excel or learn it for the first time.

Please post a link to a video that has been helpful and let me know what resource you think is most useful. Is there a different website that has been helpful?
