I am retired and returning to my former (undergraduate) study of German. Currently I am beginning German Second and Third Years by Harry F. Reinert and Walter Kleinmann, Revised Edition (1994 ISBN 978-0-87720-577-7). I would very much like to get an answer key.
I have done a Google search and only came up with a digital one on Amazon which required that it be purchased for delivery to a school address.
Any suggestions?
