i second that!
The barron's appears ok, but I have found a few mistakes myself...
The one benefit to the barron's book is that Lehman (author) has some valuable advice and resources found at the end of the book, such as helpful advice on how to prepare for the dat,(not with barron's 🙂 ), what to expect in the interview, etc,....
i found the kaplan to be very helpful, and improved on my retake by 2 on the percep, and 1 on the academic..
take care, and good luck
