Grades are click-able menus that appear to the right of the subject titles when you write reports. In printouts they appear just after report text. They are a quick and easy way of putting 'results' information into subjects.
To choose a grade, hover your mouse over a grade 'button', it will turn red, click it and the grade menu will appear.
Grades appear in printouts just below the subject text, only grades that are not '- - -' will be present.
