The Holland Interest Inventory, which is available here, is an electronic version which will calculate your career pathway based on your interests and abilities. The best way to use this file is to download it to your computer by saving it and then opening it from your computer or x-drive. Saving it will allow you to use the file within M.S. Excel and not through an internet browser.
Make sure to follow the directions and use a CAPITAL "X," not a lower-case "x."
