Hi GMATMuggle.
One person who worked with me started at 380 and ended up scoring 750.
It took her a while, but she kept finding ways to make her score go higher, and, eventually, she blew away her target.
I believe that a key reason that she succeeded in hitting her score goal is that she realized what the GMAT actually tests, which is not math or grammar, but skill in getting things done. Sure you need math skills and some knowledge of the English language in order to score over 700. At the same time, what you really need is an eye for detail, skill in coming up with ways to find correct answers, strong logical reasoning skills, and the ability to be careful and accurate in your work.
So, as you are preparing for the GMAT - notice, I said "preparing", not just studying - make sure that, in addition to strengthening your math skills and learning language rules, you develop the skills listed above. and remember, the focus of your work should not be just to learn a bunch of "stuff" or to read a lot of explanations, but rather to learn to come up with ways to arrive at correct answers.
Rocking the GMAT is just a matter of having the skills to do so. If you can read English and do basic algebra, you already have most of the skills that you need. Now, to get to 700+, you have to develop your skills some more, fill in gaps in your knowledge, and learn how to apply those skills and that knowledge to getting correct answers to GMAT questions.
Clearly, you can hit your score goal. Just play the test like a game, and keep improving your game until you hit your score goal.
By the way, to get a more accurate sense of how you would score on the real GMAT and to get some experience answering questions pretty much exactly like the ones on the real test, use the official GMAT Prep practice tests available on mba.com. The first two are free, and there are four more that you can buy. Since you have a ways to go in order to hit your score goal, probably, you should use a mix of official practice tests and test prep company tests. Each time you take a practice test, review how you did, and figure out what you could learn in order to score higher on the next one.
Enjoy the game!
