When in the Post Columns - Term view of your gradebook,
the average of all grades for quarter 3 in your gradebook. This field is not directly editable because it is calculated by Aspen. To change the number grade in this column, you must change Q3 assignment grades that will affect this Q3 average.
When you click Update Post Columns, the value of Q3 is copied to Q3Grd. This is the grade that will appear in the students report card / transcript.
It is directly editable. If you edit the value for a student, a red circle with a line in it will appear. This icon simply means that the value has been changed by you. Sometimes, you will see a blue exclamation point next to the value, this means that the grade was changed by administration (e.g., with a grade change form).
