Now that we have a test grade under our belts, the WebAssign average that you will find under the "Grades" tab is calculated by averaging your present homework score (on past due homework) and your test score (counting them as 50% homework and 50% test score). What you'll see is something like the picture here. This is how the grade report would display for a student with a homework average of 98.48 and a test score of 81.
