To score an exam, head over to the Exams page by hovering your cursor over the Home button to expand the dropdown navigation pane, and selecting Exams.
Find the exam you want to score, and select the Score Exam button underneath it!
Input your answers, then click to move on to the Next Section.
(You can also use the Score This Section button to quickly see what you answered correctly, and incorrectly, on an individual section.)
After inputting your answers for all exam sections, click the Score Exam button!
The question mark in the far right column will mark a question as a "guess." This should be used for anything you (you guessed it!) guessed on, or any questions you didn't have time to get to. The guess marker will not change your score, but it will flag those questions, making them easier for you to come back to when you review!
