Extra Practice !, 6/27/2020 By Manal Tatanaki (Stone Ridge VA)
The workbooks are in B&W, unlike the textbooks. However, the layout is still great and the pictures and illustrations are clear. I do find the workbooks essential because they provide extra practice for the material learned in the textbooks.
