CR Grading seems to be an easy way to manage grading for multiple tests. You can read the directions for each question and read each response individually, so even if you are not the one that gave the test, you can still do the appropriate grading. It is very quick too, as you just have to mark 1, 2, or 3 next to the question. Then, when you are finished, you change the question that you are grading. It seems to be quick and manageable and allows for more graders so that the tests are grading in a more timely manner.
