We have been trying to use this edition in class for the past few weeks. There are some terrible typographical errors. And then there are multiple sections where they will give two different definitions for the same term on the same page. Too many of the facts listed in the A&P; sections have been checked against other books only to find the Milady's is incorrect.Not to mention that the workbook and the text book, supposedly by the same author, will have mis-matched information in different chapters. If I was able to get a refund, I would definitely be sending both of these back to Amazon. (So would my instructor and several classmates)
