Well, I can't really do much other than assure you that it's true.
If it helps my case any, you should note that as far as the GMAT is concerned, I happened to be in a particularly favourable position. English is effectively my native language, and I'm not all that many years out of high school; both of these mean that it took less time for me to "catch up" than it would for many test-takers, who seem to me to be up to 30 years old and native speakers of languages other than English. In addition, my classes in high school included a large helping of mathematics (A-level Mathematics, Further Mathematics, and Physics), which likely helped fortify my quantitative ability.
It just happens that English and mathematics are, and have always been, two of my strongest subjects. I'm certainly no genius - if the GMAT tested my Mandarin Chinese, or my geography, then I'd probably have landed at a total score of 200. If I'd become a Literature student in high school like I was planning to as a teenager, I'd likely have needed a lot more time preparing for the GMAT. It might be a flaw of the GMAT that it only tests these two subjects, but I figure that that's why MBA applications consider more than just the GMAT.
That being said, I do feel that the GMAT Pill suited
my style of learning particularly well. Other programs may well work better for some of you, and you should certainly feel free to look at all of your options. Think about what's worked best for you in the past, and figure it out from there. If you're great at studying alone, then
the Official Guide might suffice, saving you a whole lot of money - I've heard of some engineers whose native language is English scoring in the high 700's with just a day or two of flipping through the
OG. If you feel that you need an actual person coaching you, then I hear that
Manhattan GMAT's private tutoring is of a pretty high standard, albeit at a fairly high cost, as well. There is
Kaplan, which seems to be "the establishment". Or there are possibly tens or hundreds of other options out there.
As mentioned, preparation really does seem to be the key to scoring on the GMAT. For the reasons mentioned above, most of you will likely need more time preparing for it than I did. Some of you will barely need any time at all. Just figure out what works for you, and run with it.

P.S. - Santanu: My very first practice test was taken waaaay before I started my preparation for the GMAT, and it was one of those free, downloadable ones from a signup website. I was, at the time, still thinking about whether an MBA would be "NPV-positive" for me. I'm not sure about the reliability of CATs from outside of the official GMAT Prep program, which is why I say "about" 700.
