As you're in the student role in this course, you're already seeing things from the student perspective. However, when you're an instructor in a course, you'll often want to ensure you have everything setup correctly by using a student view. Canvas does have this option.

Enter Student View

Click "Settings" in the course menu.
Click the "Student View" button on the far right.

Exit Student View

While in student view, your screen will have a magenta border and a magenta ribbon at the bottom.

If you're reviewing a quiz or assignment in student view, you will be limited to the same rules as normal students. This means that if you have a quiz set to 1 attempt, you will only be able to go through it once. However, you can clear all activity you've taken in student view by clicking the "Reset Student" button at the bottom right. This will allow you to attempt a quiz/assignment/etc. multiple times.
When you are ready to return to your normal course role, click the "Leave Student View" button.
