Follow the below steps to create demonstration accounts.
Sign in and click Administration.
Click Classes.
Click New Class.
Enter the Name of your demonstration class, select the order of tests, and click Save Class.
It is helpful to name the class something like "demonstration" or "demo" to distinguish it from the other classes in the school easily.
Click Students. Click + Student.
Enter demonstration student account information.
It is helpful to use "Demonstration" and "Student" as the first and last names for the new account to make it clear to others accessing school data that this is not a real student account. For example, first and last names could be Demo Student1, Demo Student2. The usernames could be demo1, demo2, etc.
Delete demonstration student accounts after you have completed your demonstration testing.
After you use the demonstration accounts, you should delete accounts so this data is not integrated into the overall school data. Click the check box next to the student's name and then click delete students. Or you can select the demonstration class in the Class filter and click the checkbox at the top of the list to select all students. Then click Delete.
