When a student changes to a different class in your LMS, their work in the NROC Course Manager cannot be moved to the new class. Be sure that the student has access to the old class so they can finish the last unit they were working on. Then they can start the next unit in the new class.
If changing classes partway through a unit is unavoidable, the student will have to start the previous unit over again.
The student in Class A is moving to Class B. They are in the middle of Unit 3.
Ideally, the student should finish Unit 3 in Class A, and start Unit 4 in Class B.
If this is not possible, they would have to start Unit 3 over in Class B.
