The Student View feature allows you, the instructor,  to see what 
your students see. As the instructor you can use "Test Student" to 
submit activities as an enrolled student. This is a useful tool for 
double checking if you have released enough or too much information to 
your students at any one time. 

 
Once your material is published.  A "Test Student" is automatically enrolled in your Gradebook. This
 is useful to check the information is displayed correctly. With the 
"Test Student" as a lecturer you can submit as a student to test the 
Canvas grading options. 
Once you have all your material 
uploaded or assignments created, double 
check any items that need be visible or hidden to students at particular dates and times. 
Use your "Test Student" tool to submit 
work and test the grading options. Once you are happy with what the 
student can view, you can reset Test Student for the next test.
