Hello,
accountingbozo. I can relate to your story, although I was never anywhere near national-level talented in mathematics when I was younger. I was strong at basic computation, the same sort it sounds as though you excelled at. I was fortunate to have strong mathematics teachers through most of high school. But just before my senior year, the teacher who had taught calculus for decades retired, and the school district, in a scramble to find a replacement, plucked some graduate student out of a local community college. My AP Calculus course was a joke. The teacher had no handle on the class, and he did not understand some of the very problems he assigned us, so no one respected him or wanted to listen to what he had to say. Calculus has been an achilles heel ever since. I never took the time to study it properly, so every few years, I come back to it and remind myself that I can learn it if I want to. This type of undisciplined approach affected my GMAT™ preparation. When you say that you will likely attempt to steer each problem back into "what you are good at," that is
exactly what you will do, and you will only reinforce bad habits that you might develop early on.
To keep from being your own worst enemy, I would suggest one of a few possible avenues:
1) Read through the
Ultimate GMAT Quantitative Megathread on this site. Comb through the theory, step by step, asking questions any time you need clarification, until you have reached the end.
2) Read through the
GRE® Math Review packet on the ETS website if the above proves too advanced. I think the PDF does an excellent job of explaining relevant terms and properties from the ground up, and the overlap between GRE® and GMAT™ quant is quite high. (The former may focus more on data tables and statistics, more pertinent to the IR section on the latter.)
3) Purchase a subscription to a dedicated online learning module, such as
Target Test Prep. You will go through, lesson by lesson, everything you need to cover for the test, and the cost is a fraction of that for tutoring.
4) If self-study is not getting the job done, hire a professional to assist you. Some well-qualified tutors can run as low as $30 an hour, while the more expensive ones can charge several hundred an hour. (I have no idea what your preferences or budget may be.)
5) Again, if self-study will not work for you, then you could always sign up for a full course. Both
Manhattan Prep and Veritas Prep offer such courses, and although they are expensive (in the eyes of many), you are guaranteed to be taught the ins and outs of the test by a 99th-percentile instructor.
6) Purchase an Official Guide and cross your fingers that the Math Review chapter will be sufficient. Accept that some concepts may elude you, but practice to the point of becoming adept at the question types that suit your strengths.
Depending on your target scores and schools, you may find any of these approaches acceptable. Good luck, whatever you decide.
