With Test #1 finished, here's the report. A total of 64 students took the test. The class average was 87.4 and the class median was 94 (i.e. half the students who took the test made a score of 94 or above).
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.
