You must be as accurate as possible when creating your solutions since more accurate information will result in more accurate scoring. Use the “zoom” tool and the “full-screen cursor” to make it easier to create more accurate solutions. A “check” tool is provided in several vignettes to help you identify problem areas such as overlapping elements. Tolerances are built into each scoring program that allow for slight inaccuracies. These tolerances vary from vignette to vignette based on the importance of the feature being evaluated.
