Reports submitted after the due date will be considered late and will be graded according to the following equation:

How to use the Excel grading rubric: The "fixed scale" grading sheet is based on a "poor" to "excellent" 5-point scale with the points on the scale equal to 0.0, 0.25, 0.5, 0.75, and 1.0, respectively. These values are locked and are not changeable without unlocking the worksheet.
