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, then you can’t assume that x is an integer, and you…

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 and learning how to identify them. In this and subsequent…

The Logic of GMAT Data Sufficiency

I recently received an e-mail from someone undergoing a mini-crisis over GMAT Data Sufficiency.

Along with requiring an abundance of abstract thought, its strange wording and structure naturally induce students to make mistakes. Here, I’m going to discuss the #1 mistake students make on data sufficiency: They don’t evaluate the statements independently! Let’s look at a…

How to study (and not study) for the GMAT

A wise dude named Einstein once defined insanity as such: “Doing the same thing over and over again and expecting different results.” Despite the somewhat philosophical tenor of this quote, I find it highly applicable to the situation that confronts many GMAT test-takers. Having developed and familiarized themselves with a certain approach, many GMATers come to practice that approach habitually, even when it yields less-than-desirable…

The downside of commercial GMAT materials

As a full-time GMAT tutor and a frequent reader of GMAT forums, I see many students who spend a decent chunk of their prep time using commercial materials. In a way, the use of commercial practice questions is almost inevitable: If you sign up with a company, you do so with the belief that its materials will accurately reflect what’s on the GMAT, and you…
