This portion of the self-evaluation is designed to test your knowledge of the ridge quality (clarity) map and center point of reference.

To mark clarity:

Select a paintbrush color, then click and drag on the canvas to paint an area that color. Adjust the paintbrush size by clicking the paintbrush icon and using the slider that appears. Click on the eraser to switch your cursor to an Erase tool.

The guidelines for each color are below. In each case, if there is doubt as to which level of ridge quality to assign, use the lower quality.

To mark the center point of reference:

Determine whether you want to mark a center point of reference or a lateral centerline, then select that tool. For the center point of reference, click on the center point, then click again to set a radius of uncertainty. For a lateral centerline, the mouse's vertical position doesn't matter. Click anywhere along that vertical line to set the lateral centerline.

Setting another center point of reference or lateral centerline will erase any existing markings. You can also use the Delete tool to clear your marking.
