When you click the "Grades" link in WebAssign you'll now see something similar to the picture shown here. This would be the current grade report for a student having a 93.69 homework average (based on the homework assignments that have come due) and a 99 score on Test #1. This translates to a current grade estimate of 96.41. You can click any of the blue text to get the calculation detail on how that number is determined.
Generally the first test has the highest class average. So even if you did well on this test, don't rest on your laurels. If you didn't do as well as you would have liked on this test, give some consideration to what you might do to be better prepared in the future. There's nothing that compares to experience and practice. Since the tests are timed, you don't want to sit there scratching your head trying to figure out the approach to a question. Do contact Jenn or me if you want to discuss your standing in the class.
