Number Properties GMAT Preparation Guide (Manhattan GMAT Preparation Guide: Number Properties)
About the ManhattanGMAT Strategy GuidesThe ManhattanGMAT Strategy Guides offer students a unique balance between two competing emphases: test-taking strategies and in-depth content understanding. Most prep courses focus on the strategic portion of the GMAT - timing, shortcuts, etc. However, we believe that unless a student has a solid understanding of the content, the tricks won't be of any use.  Therefore, we include practice problem sets that build specific foundational skills in each topic as well as advanced content that many other prep books ignore.
