The only way to view your course exactly as a student sees it is to create a LaunchPad student account by signing up for free trial access.
You will need to use a different email address from your LaunchPad instructor account.
You can also access a student preview when you are signed in as an instructor, but this view will not be exactly the same as a student's experience of the site.
