They are different. Some divisions, but not a big deal. However, note that the David series is different. I would think that if you wanted to take the series and did not want to spend the money you could. I just like to buy the new one to go with the later series because you don't have to look around inside the workbook.

If they don't buy them they can still do the study. Just is easier with newer books.
