Upgrading to the Premium license won't affect your student's progress at all. They'll keep their same account with all their progress data and history. What changes is that the teacher or parent gains access to Premium features, such as printable activities and the ability to assign custom programs.
After integration with rostering methods like Clever and ClassLink can sometimes create duplicate classes and student accounts. If this happens, the student's progress will not be lost but may be found in a different student account than the one currently used for sign-in.
Please email XtraMath Technical Support (support@xtramath.org) to report this issue, and they will merge the classes and students so that each student has a single account containing all their progress.
Example
Jane Doe created a class and has been using XtraMath with her students. Her school has now added a ClassLink integration. The ClassLink sync created a new, ClassLink-linked class in her account, which had the same list of students that she had added manually earlier in the school year. However, it also created new student accounts. The students’ original accounts still have all their progress data, but it’s their new blank accounts that are linked with ClassLink sign-in. With Premium license our support team can merge the classes and students so that each student has a single account containing all progress as well as the ClassLink association. Now when a student signs in through ClassLink, they can continue where they left off prior to the integration.
