For CR Grading, you click on the CR Grading Icon from the home screen. You click on the test that has the questions you want to grade and click select. It will show you the instructions and questions as the students see them, a grading rubric, and show you a spreadsheet of the students responses. You read the response, determine the rubric score, and mark it in the bubble next to the response. Once you've graded all the responses, you can move on to the next CR question and grade the responses.
