Teaching materials from 2004, manual and DVD
Newer Student set bought a few years ago, lesson workbook and test booklet. My children used a separate notebook to write in so books are in good condition. Some pages removed for photocopying but all originals are present.
The older teaching materials worked just fine with newer student materials.
