It is difficult to read the radio buttons and tell which student they belong to because there are no lines between each row. Could you please add the option to add lines to the rows or have one row be one color, and another row be another color (for example, row 1 has a white background and row 2 has a light blue background)? This would make it easier to read, help work to be completed more quickly, and would reduce the chances of making errors. Thank you for considering this request.
