My philosophy
For many years now, I have looked at the GMAT as much more than an entrance exam to get into a good business school.
Due to the amount of effort that is usually required to reach a desirable score, the GMAT offers those who are up for the challenge a unique opportunity. Achieving greatness on the GMAT is about much more than mastering the content. In many ways it is about achieving mastery of self.
Like a professional athlete or musician who learns to master his/her craft from hours of careful study and self-discipline, most successful high GMAT scorers have not only learned the Content inside and out, but they have also perfected the Processes and Strategies that are needed to succeed. I like to call this putting the “pieces” (PCS) together:
P = Process
C = Content
S = Strategy
Process
Scoring well on the GMAT requires a very high measure of accuracy on questions that are at or below your desired score level (though much less so for questions above that level since an adaptive test expects you to miss those). In addition, you have to be able to keep your cool under the extra pressure of the ticking clock.
The answer to both challenges lies in having a fine-tuned process. Like a pilot who has carefully honed the protocol that he/she must be able to blindly undertake before flying a plane, the successful test-taker must have a well-rehearsed process for each question type on the test.
Achieving this means taking apart every detail of the solving process including: how to read the question, when to start writing — if at all, what to write, how to organize your scratch pad, what internal questions to ask in order to advance your thought process, and how and when to use process of elimination on the answer choices. Practice is essential, and consistency is paramount. From the outset, I work closely with my students to first observe their innate processes and then to help them instill the best practices to ensure repeatable success.
Content
To do well on the test you also need to have a pretty thorough mastery of all of the content tested. I say pretty thorough because sometimes you can get away with a slightly less-than-perfect understanding of the content, if for example you employ a more practical strategy on a Quant question. In general though, content mastery is particularly relevant for Sentence Correction questions (i.e. grammar rules) and for the entire Quantitative section.
It might surprise you, however, that the issue that I find that most students have with content is less about understanding the “what” of the content, and more about the “how” and “why”. One of the most common complaints I hear from students about the Quant section, for example, is “I often don’t understand what they are asking. Once I understand what they are asking, I can do the math”.
Welcome to the GMAT! Key to content mastery is understanding how to recognize what they are asking: how to break down the language and recognize key phrasing that indicates a certain topic or set of relationships (e.g. why is this question testing perfect squares, or inverse proportionality, or adverbial modifiers, or parallelism…).
This is an integral part of content mastery. When I teach my students the content of the exam, I always insist on them demonstrating the ability to apply their knowledge in the context of real questions, with an understanding of why it is relevant to do so in each case. I also rely heavily on a kind of analysis similar to what doctors call “differential diagnosis”; in this process we look at similar presentations and learn to distinguish different content subtleties or areas.
Strategy
Arguably one of the most important secret ingredients to success on the GMAT is the use of strategy. The term strategy here refers to a few different aspects of preparation. Time management is one important aspect. The clock creates a clear and present challenge for most test-takers, especially on the Quant section of the exam. Learning how to manage your time on the Quant section, including benchmarking, strategically guessing when necessary, and proper pacing, is a vital part of your preparation.
A second integral part of strategy, though only relevant for the Quant section, involves different methods for approaching questions. I use the acronym MPC to encompass the variety of options that are often available for solving most Quant questions.
M = Mathematical
P = Practical
C = Conceptual
The Mathematical involves the more traditional use of Algebraic tools, i.e. writing and/or simplifying algebraic equations or expressions. The Practical entails more hands-on “plugging and chugging”, estimating, or computing. Finally, the Conceptual involves more abstract reasoning based on mathematical definitions or properties. Being able to properly blend these strategies in a way that is both suited to an individual’s particularly skill set and to the nature of the question is something I work on at length with my students.
Finally, the ability to navigate common traps and pitfalls and to strategically guess when necessary (part of time management) encompass another aspect of strategy that I emphasize throughout my work with students. In many ways being strategic on the GMAT involves staying ahead of the curve, the curve that the test writers are intentionally trying to set in order to delineate different levels of scorers.
Of course, the “pieces” (PCS) of the GMAT do not exist independently from one another, but rather are intimately linked to one another. Content mastery is aided by an intimate knowledge of various strategies that can be used to solve a given question. Good process goes a long way to helping you maintain good time management. Proper preparation for this exam should involve learning these skills and then practicing them both in unison and then in conjunction as they will actually be used on test day.
