Let's be honest. For most people the process of preparing for the GMAT is long and arduous. The GMAT is like the SAT and GRE, is out on steroids, and the algorithm of the test, take steps to expose weaknesses in your knowledge or conceptual approach. For most people, these facts lead inevitably to a view of the GMAT, which is somewhere between resignation and downright disgust. And to be honest, I can not blame you entirely. If you work full time and spend hours and hours, the number of properties are data sufficiency questions and modifiers in their free time, you're probably a little justified in all the hatred you have for testing. But the truth is that, as far as your preparation is concerned, this kind of thinking is contra-productive.
To really beat the GMAT, you must enter the minds of politicians, the logic of questions and problems that these issues are fundamental test to test. I do not want to count how many students I had, instead of this approach based on the content, have approached their studies with the mentality that A) to cheat on the GMAT and B) The only way to do well on the GMAT test It is the decision-makers with their own weapons, with different tricks and shortcuts. Instead of considering the test as a game full of tips and labyrinths, you should take a structuralist approach. Once you study enough to test and understand that the test makers are really testing a finite number of concepts, you will be better able to answer a question that is not really a question of finding an exit to understand, but rather a question of the categorization of the problem and a strategy, the question (I hope) that you developed through hours of practice.
Of course I can not deny that the GMAT is to throw some questions to you absolutely brutal, but I am firm in my belief that what makes the hard GMAT test is that the decision to take simple concepts and bring them into the Orthodox situations. The test-makers want, it is difficult to see what is really happening in the questions, they are strange in a large number of variables or manipulations that you are in what would be a simple question and submit. Again, the best antidote is not about gazillion links to learn by heart. There is little time to understand what the question is really, really getting at, then proceed as for any other question under this category. What is striking is that the more you practice this approach, the better you'll be the next time you encounter a similar situation to be. What you also notice is that, rather than a confrontational approach towards the GMAT you approach, you will see the review as it really is: a test of your ability to process and analyze information in a finite time period. Now I'm not saying this approach will magically result in a 760, but it will do is align your thought process with that of the test-maker - which is ultimately a good thing.
