Just as students must correct mistakes in assignments and Mixed Review, students correct errors on exams after the teacher has saved grades and enabled Corrections.
Corrections for an exam show on a student's screen above the dotted line.
From the student's view, corrections are completed by correcting the mistakes and practicing for the follow-up exam by solving the $ problems above the dotted line.
After the student corrects the mistakes from the exam and earns a point on a similar problem, the student will have $ problems above and below the dotted line.
Remember, the $ sign prioritizes practice for each student.
