A window will pop up prompting you to log in to Google. Log in using the .edu email address associated with your Google Classroom account.

Choose a classroom to import and press the “import” button.

Your Google classroom is now imported into Study.com! Any students that are enrolled in your Google Classroom will be put in "pending." Their accounts will be confirmed as soon as they sign in to Study.com for the first time and take their first assignment.
