That is a great question, to which I do not know the answer. What I have done is created one large (11x13) envelope for each high school course. On the outside I tape a printout of the blank subject assignment/grade page from MySeton. As assignments are completed and graded, they go in the envelope. When the course is done, the envelope goes into a Banker’s box. By graduation the box is full and it goes on the shelf. 1 box!
