How the System Indicates Grading Status
The main view of the feature will flag any assignment that needs grading with an icon that looks like a calculator with an explanation point. Additionally, the Status column includes a notation of the number of students whose assignments need grading.
When you navigate to the assignment overview, each student whose work needs grading is also marked with the calculator/exclamation-point icon and highlighted in yellow.
When you view the Student List, if any students have assignments that need grading, you will see the same yellow highlighting and calculator/exclamation-point icon.
