Click on "My Sections" in the top bar, then “View Teacher Page”.
On the top right of your teacher page, click the "Create New Section" button.
To create a new section, you now have two options. You can either import a class from Google Classroom, or you can create a new section on CodeHS.
For more information on importing your roster from Google Classroom, check out this article: http://help.codehs.com/managing-your-sections-and-rosters/how-do-i-sync-my-google-classroom-roster-on-codehs
To create a section on CodeHS (if you're not importing from Google Classroom), start by giving it a name.
Then, you can choose the course you want to enroll your new section in. You can filter on courses designed for High School, Middle School, or other courses you may be enrolled in, like playlists.
After selecting the main course, you can either invite your students by email or share the generated URL with them so that they can enroll in your new class!
