Sometimes, when there is a lot of text within the common wrong answer or correct answer rows (rows 2 and 3 of your assignment report), it will become large and take up a lot of space on the screen, making it difficult to see student responses.
We recommend collapsing the first few rows of the assignment report by clicking on the black triangle to the left of "Problem/Student" column title. This will allow you to see and scroll through your student data more easily.
