I have taken a couple of sample exams and I barely managed to score
around 600. I did not find the questions particularly hard per se, but hard in the sense that you have to answer them in the allotted amount of time (about 2 minutes a pop). Since this exam is obviously designed to measure innate abilities, like the ability to perform a set of thinking tasks in a given amount of time, and since I am obviously no genius, do I have a realistic chance of hitting 700 if I work my butt off? By working my butt off, I mean taking at least 2 sample tests every weekend for about 6 months.
I ask this because companies like Kaplan, and Princeton Review, and possibly even this website, will tell you that your score will improve just to lure you into buying their products and paying for their services. They'll also post "stickys" describing isolated success stories, while ignoring the vast majority failure stories. But don't get me wrong, they might be right, my score might improve, but for all I know that means my score will increase by 2 to 3%, simply because I'll be more familiar with the format of the exam and the type of questions I will be asked. So instead of scoring a 600 I would score a 615, (like that makes a difference).
Bottom line being, is my expectation unrealistically high? Are there real cases of
normal people who started off scoring in the 600 range, and then progressively 'conditioned' their brain to perform at the 700 level?
