## GMAT Verbal: Think Before You Write

The GMAT Verbal can be tough to crack. While GMAT Quantitative percentiles have been steadily increasing over the years (compare old GMAT Quant Percentiles from 2007 to this current Quant percentile chart), Verbal scores have mostly stagnated, with, for example, a 40 scaled score from 2007 corresponding to same percentile now (again, compare old GMAT…

## GMAT Verbal: Can You Really Improve Your Critical Reasoning?

Conventional GMAT wisdom suggests that you should spend the majority of your time preparing for the Quantitative section. The reasoning behind this claim is largely valid: The Quantitative section tests mathematical reasoning in a highly nuanced way, and before you can even begin to learn and recognize these nuances, you need to brush up on…

Everyone who takes the GMAT suffers from at least some anxiety. I’ve taken it three times and scored 760+ each time, but even at my last sitting, I remember feeling that rush of adrenaline and nerves as the test started. In the back of your mind, you will always wonder whether they will suddenly throw…

## GMAT Calculations: Avoid the Dirty Work!

If you’ve been studying for the GMAT, you’ve inevitably found yourself in a situation where you were thinking “If only I had a calculator!” Many of my students express this sentiment, especially when doing weird digits questions or when forced to evaluate seemingly impossible percentages or fractions. I’m going to say here what I tell…

## Factoring Exponential Expressions

Most of the time on the GMAT, manipulations with exponents are fairly straightforward. Usually, you’ll see two terms with a common base, and you’ll be expected to divide or multiply those terms (such as: 25 / 23 or 35 x 38). However, when you get to some of the higher-level questions, you’ll be expected to handle situations in which…

## Causality on the GMAT

One of the most common types of arguments you’ll see on the GMAT will be cause-and-effect. A cause-and-effect argument can best be thought of as one arguing that a certain fact or phenomenon directly brings about another one. One of the pitfalls of any causal argument is that the seemingly apparent causal connection might not…

## GMAT Quantitative Concept: Disguised Quadratics

If you’ve been studying for the GMAT, you’ve probably encountered situations that require knowledge of quadratic equations and how they work. In so doing, you’ve also probably memorized the following three equivalencies: (x + y)2 = x2 + 2xy + y2 (x – y)2 = x2 – 2xy + y2 (x – y)(x + y) = x2 – y2 Knowledge of these…

## GMAT Data Sufficiency: Breaking Your Assumptions

One of the most widespread mistakes I see students make on Data Sufficiency concerns the information they consider when evaluating a statement. To properly determine whether a statement is sufficient, you must be focused on using only the information given. If, for example, a statement only tells you that -10 < x < 10, but says nothing else,…

## GMAT Anxiety: Do Something!

As a full-time GMAT tutor, I work with many people who have taken the exam at least once before, and, in many cases, multiple times. For many of these students, the GMAT is no longer “just” a test they need to get into a good business school, but something almost existential. Though I hesitate to…

## GMAT Sentence Correction: Relative Clauses

As an independent GMAT tutor, I find that many of the students I work with struggle on Sentence Correction because they find it difficult to breach the gap between grammatical intuitions and concrete grammatical rules. In such cases, I find that students benefit most from clearly delineating the grammatical rules that appear on the test…
