You can select the Grader Report within the Grades menu:
The grader report is a great view for getting a quick glance at your grade book. I would not recommend using the Grader Report to enter grades on a consistent basis. Instead, I would suggest that the Grader Report should be used to override grades that were mistakenly entered. If you do this, the grade will change to a yellow color (which indicates that a grade has been overridden from what was originally awarded). There is a time and place for the grader report view, but I would not recommend exclusively entering grades from that view.
