Classes are loaded or synchronized from your classes in your Google Classroom account. You have to set up your classes and students in Google Classroom first, if you have not done it already, to use Smoothwall Classroom Manager. Once your classes are loaded, you can click a class to start a session and remove any students not present.
Classroom Manager only supports the Chrome browser for now. Therefore, if you used Internet Explorer or Firefox, we recommend that you download and use Chrome to get the best performance for Classroom Manager.
