I'm not sure about either of these, as I have Crack DAT math.... which I think is an "okay" representation.... however, just an fyi if your looking to brush up on how to approach and solve some of the problem on the QR I found that "The Complete Idiot's Guide to Algebra Word Problems" was a freaking god send! (and free because I borrowed it from my local library) ..I've read in other forums that the real DAT has many word problems. This book provided MUCH better explanations that Crack DAT Math.
