Please note
If you are a part of only one class on Sowiso, do not archive it! If you archive your only class, you won't be able to get back into it again. The only way to get back in is by contacting support.
Watch a quick video:
To archive a class, go to Settings at the bottom left. Under "Manage classes" choose "Archive class".
To see the full archive, click on "Archived classes".
Then click on "Restore" to remove the class from the archive and use it again.
