The version in Logos is very poor quality in terms of graphics. Perhaps where the book has been edited, the graphic that is pasted in is 99% of the time unreadable, which is a slight problem when the graphics are of vowels, boxes, etc. The workbook that goes with this course is of the same quality. In terms of learning the material, I felt like the content is organized best for a scavenger hunt. Imperative information is buried in footnotes often and trying to identify a clear path to success in terms of learning the material is difficult.
