So, although I got good scores in the practice tests, my concern is that they could evaluate something new. Should I study more?, or when could I say "I'm ready"?
I would say: think about it. You are very ambitious. Your idea of a "great score" is something in the 99th percentile. It's great to be ambitious, and clearly you have an excellent shot at those elite scores. Nevertheless, think about what this means. If you are in the 99th percentile, you are doing better than 99% of GMAT test takers, some of whom are exceptionally bright people. Yes, there are some people who don't learn all the rules, don't know half the idioms, don't know grammar, etc., and they constitute the lower reaches of the percentile spread. Then, toward the upper reaches, there are plenty of people who know grammar well, who have studied the rules & idioms thoroughly, and who can answer a question on absolutely anything they have seen before. The separator for scores at this elite level has to be --- if everyone can nail the problem types they have already seen, how do they do on something completely out-of-the-box that they have never seen before
? In many ways, that's one of the chief separators at highest score levels on both Q & V.
There's a paradox here. If you can reliably do everything that you have already seen, then you are "ready" for that stuff, but so can, say, a good 5% of other GMAT test takers. To be ready only on that level is, say, 95th percentile --- not bad, but not what you want. To beat out many of those other folks and get into the top 1%, or even more rarefied, then in addition to nailing everything you have already seen, you have to be able to handle brand new, wildly out-of-the-box stuff that you have never seen before. The GMAT excels at creating questions such as this for distinguishing folks at the upper end, and if you are nailing everything else, the CAT will feed you a reasonably steady diet of the hardest possible question. Some of those hard questions are hard precisely because
no one has ever seen anything like it before.
That's the paradox. How do you get to a point so you can say --- I am ready, not only for everything I have reviewed and studied, but also for everything that I will see for the first time, totally out of the blue. In other words, how will I know that I will know what to do when I don't know what to do
? We are getting into some of the very subtle issues of human intelligence here, because, in fact, all the times folks find themselves in situations in which they don't know what to do, and they figure out something to do. Creativity, at its best, is about those situations in which absolutely nobody know what to do until somebody has the brilliant flash of insight --- aha, now I know what to do
! In a way, that's what the hardest GMAT questions are asking of you, and it's not a particularly straightforward process to study for that the way one can study for specific content.
Studying and reviewing content is a more left-brain methodical approach, which is fine, but for developing creativity, that strikes me more essentially as a right-brain process. You might take a look at this post ---- it's ostensibly about math, but by analogy, it may suggest some things about GMAT SC:http://magoosh.com/gmat/2013/how-to-do- ... th-faster/
I realize this is not a simple answer, but I hope this helps.
