As far as very basic study guides go, this is a pretty good one. I don't know whether Wright himself wrote the study questions (I suspect he didn't, as some of them are a bit cheesy), but overall the book accomplishes its purpose, guiding the reader through Galatians and hitting the highlights. I did not read the companion volume, the N.T. Wright for Everyone volume on Galatians, but will probably pick up a copy soon.
