The right margin and text area is for marks and comments.
The left margin and shape rubrics (see below) are for tracking deducted points.
A deduction of "–X" is a warning that points will be deducted in your next assignment for the same error.
In the shape rubrics below, a checkmark (✔) means you lost no points for the item and a negative number means you lost that many points for the item. Each shape rubric is assignment specific.
