When I first encountered the GMAT, I was working at a major test-prep firm as a GRE and SAT instructor. At the time, I was 23 years old, and had absolutely no thoughts of business school. For that matter, I hadn't even finished my undergraduate degree; I was dancing professionally during an indefinite hiatus from university, and there was no reason why I would have any interest in the GMAT. But as luck would have it, my company needed a GMAT teacher, and I was ushered into a computer lab to take a practice test. After clobbering the ACT, SAT, and GRE, I figured that the GMAT would be basically the same deal. For the first time in my test-taking life, I did "just okay" on the practice GMAT. I did well enough to be initiated as a GMAT instructor, but I was nowhere near a perfect score.
And my curiosity was piqued.
Fast-forward eight or nine years, and I'm still playing with the GMAT. I've worked as a private tutor for a long time now, and I've spent quite a bit of time tutoring the SAT and GRE and ACT--but there's a special place in my heart (or brain?) for the GMAT.
The GMAT is, without question, the most complex and nuanced standardized test out there. There's absolutely no way to boil the GMAT down to a nice, simple series of tricks. The GRE, by contrast, employs an extremely limited set of questions; once you know what to expect on the test (particularly the quantitative section), it's just a matter of execution. The GMAT seems almost infinite, and they seem to write questions that only the most ridiculous of geniuses are able to solve. (When I took the GMAT last year, I spent eight minutes on a single question... and still had absolutely no idea how to solve it. Whoever writes these questions is a bad, bad dude.)
So that's why I'm here, all these years later. Still playing with GMAT, still trying to figure out every little nuance and evil question, so that I can offer the most help possible for my friends and students who want to achieve their MBA goals.
