REVIEW: Manhattan GMAT’s 6th Edition GEOMETRY Strategy Guide:

by on January 23rd, 2015

As I specified in my review of Algebra Strategy Guide, Manhattan GMAT’s 6th Edition Strategy Guides arrived on 2nd December. If you just came to know about these guides, I encourage you to first go through the Information discussed in Stacey’s two part article linked here: Part 1 and Part 2.

The below review is for the GEOMETRY Strategy Guide which is Guide No 4 in the set of 10 Strategy Guides.

ISBN: 9781941234037.


Geometry, like Algebra is an another important topic tested on the GMAT exam since we can very well expect to see a few problems on triangles or on some other shapes on test day. The Geometry Strategy Guide equips us with powerful tools to grasp and solve every geometry problem tested on the GMAT. It covers not only fundamental geometric principles and techniques but also nuanced strategies for tackling tricky questions involving polygons, circles, the coordinate plane, and many other topics. It is designed to provide deep, focused coverage of specialized areas tested on the exam. As a result, the students are bound to benefit from thorough and comprehensive subject material, detailed and clear explanations of fundamental principles, and step-by-step instructions of important techniques.

The book has a nice cover page, uses easy to understand language and consists of about 152 pages (including table of contents, some blank pages and advertisements), some 17 pages more than the previous edition. About 140 pages deal with pure solid content. It offers latest approaches for students looking to score in the top percentiles.

This is how the cover page of the book looks like:


It contains the following chapters (in order):

  1. Geometry Strategy
  2. Lines & Angles
  3. Polygons
  4. Triangles & Diagonals
  5. Circles & Cylinders
  6. Coordinate Plane
  7. Extra Geometry

Major Updates since the Last (5th) Edition

  • Sequencing of the chapters has changed from the last edition. I personally feel the sequencing is much better aligned now. Moreover, a few of the topics which were earlier present under a particular chapter have now been placed under a different chapter altogether. For example, ‘How to find equation of a line from two points’ was initially under ‘Co-ordinate plan’ chapter in the previous edition, but now have been placed under ‘Extra Geometry’ Chapter along with other topics which is a good move.
  • Introduction of 1 NEW Chapter on Important Strategies. The first chapter on Geometry Strategy outlines a great 3-step approach on all Quant problems.
  • The Strategy Guide contains 1 page sheet with all the important rules and formulas that one needs to know
  • Online access to Official Guide Problem Sets and 5 GMAT Interact Lessons.

Buying Information

The book can be purchased from various sources. It can be purchased from Manhattan GMAT’s website, from Amazon, or from any authorized retailer. The combo of hard copy + ebook access is available for 32.99$.


It is currently priced at $26 as per the information available on Manhattan GMAT’s website. Check here for more information.


  • Book is designed in a clear and an effective manner and is indeed comprehensive.
  • Each chapter discusses in good detail the theory points we need to know for the Geometry section of the GMAT.
  • Problem Sets following each chapter help in reinforcing concepts.
  • The strategy guide contains 1 entirely NEW chapter which outlines a great 3 way method to tackle any quant problem. It also provides an introduction to ‘estimation’ technique.
  • The organization of the chapters has been done well, streamlining learning in an effective way.
  • A nice introduction to Data Sufficiency with sample problems during the end of the book is a welcome addition. (Please note that this chapter is same across all the quant strategy guides).
  • The book does a good job of mimicking the style of questions found on the actual exam.
  • Detailed explanations to the problem sets at the end of each chapter will challenge the student to do better while topical sets of Official Guide Problems will provide the opportunity for further growth.
  • A copy of this strategy guide gives access to 6 online Manhattan CATs, Geometry online question bank of 25 questions of varying difficulty, 5 GMAT Interact Lessons and Official Guide Problem Sets. (The online resources won’t be available until we register our product on the website and are available for one year from the date of registering).


  • No information about Tangents to circles in the book. A small introduction plus a few practice problems would have been sufficient.
  • Problem sets of few chapters do not have more practice problems. Some of the chapters where I was looking to see more problems are: Triangles & Diagonals, Circles & Cylinders. Moreover—it would have been nice if there have been a separate chapter on ‘Overlapping Shapes’ or some practice problems on ‘calculate the shaded area’ question types that typically involve two or more shapes. These problems are generally very challenging in my opinion.

Bottom Line

Used by itself or with other Manhattan Prep Strategy Guides, the Geometry GMAT Strategy Guide will help students develop all the knowledge, skills, and strategic thinking necessary for success on the GMAT. It provides 60 practice problems of varying difficulty levels.

Rating: 4.5/5

P.S.: If you are going back to study mode after a few years of gap, you may find the information in the book a bit tempting. So, you may want to start with a Quant foundation book (Manhattan Prep’s Foundations of GMAT Math strategy guide, for example) first before getting your hands on this strategy guide. This is just a warning and in no way be taken as a critique to the book.

As a side note, please do expect to see some overlap in the review within the Quant Strategy Guides. All of Manhattan Prep’s GMAT Strategy Guides are aligned with BOTH the 2015 Edition and 13th Edition GMAT Official Guide.
