Practice Records & Account Recovery

Bookmarks and exam lists are currently stored in this browser and do not sync across devices. If you forget your password, contact your teacher for account verification and a one-time recovery code.

Class Assessments

When an educator adds your registered account to a class, your assigned assessments, draft responses, submissions, scores and feedback are stored in the private account database. The educator who owns the class can review your participation, draft responses and submitted work. You can view your own responses and published results; other students cannot view them. No student email, response or score is included in a code package.
