Great material to strengthen your performance with Number properties. Some typos.
I downloaded the Nook book and found it very handy for studying. The Nook book is considerably cheaper than the print book and you get full access to 6 practice tests after e-mailing MGMAT your proof of purchase. The content is a great refresher of rules and has some practice sets. Chapters 9 and 13 point to the relevant questions in the official GMAT guide. Occasionally there are a few typos. E.g. on page 49, you are asked to calculate the number of multiples of 7 that are between 100 and 150. The explanation states: Number of terms= (Last-First)-increment+1 = ( 147 / 105) / 7 +1 = 6 +1 = 7.Was this review helpful? Yes NoThank you for your feedback.

Clearly this should be:
Number of terms= (Last-First)/ increment+1 = ( 147 - 105) / 7 +1 = 6 +1 = 7.
Generally the occasional typo does not interfere with the meaning, but is a nuisance.
