For most courses when you complete an Activity (quiz) or a Chapter quiz you are provided with the answers.
When you review your answers make sure that you carefully read the questions as well as the answer options as they might not be displayed in the order you saw them when taking the quiz initially.
The system will show you which is the correct answer as well as which is the answer you chose.
Here is an example of a quiz question answered INCORRECTLY:
In this case the correct answer to this question would be A: 204.71 and it is displayed under "Correct Answer"
The student chose the wrong answer C:205.46 which is displayed under "Your Answer"
When a question is answered incorrectly the system provides the student with feedback, displayed under the blue tabs.
Here is an example of a quiz question answered CORRECTLY:
When the student's quiz answer is correct then both the "Correct Answer" as well as "Your Answer" will match.
Also the feedback box will display the words "Your answer is correct"
