If a student has been accidentally removed, they can easily be re-enrolled. The student's work should also be restored by completing these steps.
2. The student will select "Sign In" on the login page next to "Already have a Science Interactive account?"

Note that the student must select this "Sign In" link. The link on the upper-right hand corner will not complete the process correctly.
