In my last GMAT blog post, I mentioned that it’s possible—at least in theory—to apply to nearly any major MBA program with only a GRE score. Very few top MBA programs (hello, BYU and Haas!) stubbornly refuse to accept GRE scores, and the creators of the GRE have generously produced a handy GRE to GMAT score converter to make the GRE more appealing to MBA admissions committees. You could easily argue that MBA admissions committees aren’t 100% comfortable with the GRE yet, but it’s certainly possible to be admitted to most MBA programs without touching a GMAT book. So if you’re completely convinced that you’ll do better on GRE than on the GMAT, then there’s no reason to hesitate.
Which brings us to the next question: what are the differences between the two tests, and what are the chances that you’ll actually do better on the GRE than on the GMAT? Although I think that most people will score similarly on the two tests, it’s conceivable that you could gain an advantage by taking the GRE, depending on whether the differences between the two tests work in your favor.
The first major difference between the GRE and the GMAT is probably irrelevant to your odds of admission to business school, at least for now. The GRE includes two 30-minute writing assessments, instead of the GMAT’s combo meal of one AWA and one 30-minute Integrated Reasoning exercise. But as you hopefully know already, neither the AWA nor the Integrated Reasoning is likely to have a substantial impact on your odds of admission. So at least for the next few years, that particular difference between the GRE and the GMAT doesn’t really matter.
On the quant side, the GRE lacks the data sufficiency that all GMAT test-takers (*cough*) dearly love; instead, the GRE includes a less-tricky question type called quantitative comparisons. The GRE also includes some numeric entry questions that require you to come up with an actual number yourself. And the GRE also gives you data analysis questions, which aren’t terribly common on the quant section of the GMAT. So if you hate data sufficiency and love data analysis, you might be happier taking the GRE. (The GRE also offers a simple on-screen calculator, but I’d argue that it really doesn’t help all that much—the numbers are rarely cumbersome on either exam, especially if you’re well-trained in the art of finding intelligent quant shortcuts.)
On the verbal sections, the differences between the GRE and the GMAT are substantial. Both exams include some sort of reading comprehension and critical reasoning questions, but the GRE has no sentence correction questions. Instead, you’ll face some vocabulary-heavy text completion and sentence equivalence questions. So if you have a strong vocabulary and hate GMAT sentence correction, then maybe the GRE is for you.
Structurally, there are also some major differences between the GMAT and the GRE. The GRE has several shorter sections and only one extended break, roughly two hours into the test. I would argue that the GRE feels like running wind sprints: once you finish your two 30-minute AWA sections on the GRE, you’ll suffer through two scored quant sections (35 minutes each), two unscored verbal sections (30 minutes each), and one experimental section, which could be either quant or verbal. The GMAT, of course, includes one 75-minute quant section and one 75-minute verbal section. The total amount of test-taking pain is similar, but the heart of the GMAT consists of two long, painful marathons, instead of a set of shorter sprints. I’m not sure which is worse, but I promise that I’ll whine about the GRE’s format in my next blog post, after I retake the GRE for the first time in several years.
And now for the most important difference between the two tests: the GMAT is question-level adaptive, while the GRE is section-level adaptive. If you get a few consecutive questions correct on the GMAT, you’re likely to see tougher questions almost immediately. But the GRE only “adapts” between sections. If you do really well on the first quant section, then your second quant section will be extremely difficult. And it won’t matter what you do with the first few questions within each GRE section—the test doesn’t adapt until you move from the first quant section to the second quant section, or from the first verbal section to the second verbal section.
In some ways, that’s absolutely wonderful: on the GRE, each 20-question section is “fixed” once you start the section, which means that you can go back and review the questions that you’ve already completed within that section. It’s a completely different test-taking experience than the GMAT. Most of us feel much more comfortable with the GRE in this respect; there’s something extremely comforting about the idea that we can skip questions and come back to them later, or revise our answers if we have extra time at the end of any given section.
So yes, the two tests are substantially different, but the bad news is that I’ve seen plenty of students take both exams, and their GRE scores tend to be very comparable to their GMAT scores. But if you’re absolutely convinced that GRE questions will be systematically easier for you than their GMAT counterparts, then don’t hold back: the GRE might be ideal for you. If you’re not convinced that you’ll perform substantially better on the GRE, then stick with the GMAT: you never know when you might fall in love with Haas or BYU, and regret your decision to abandon the GMAT in favor of the GRE.
