Hi @tslee ...
In addition to the great advice that you got from @james_whalley, I wanted to let you know that you can make suggestions to the written Guides here in the Community if you feel the documentation is not clear (or even if you find errors that need to be corrected). For example, in the Guide that you linked to:
How do I view a course as a test student using Student View?
...at the bottom of the Guide, you'll find a blue button for "Leave Feedback". This will open up a window where you can fill out a form about the Guide you are viewing to provide your suggestions. The Documentation Team will review your feedback and determine if any changes are necessary.
I hope this extra bit of information will be helpful to you.
