Contrary to the general belief that people from engineering background will find GMAT quantitative section easier, I find Quantitative section tougher than the Verbal section. My accuracy is only ~70% in Scoretop VIP Quant question sets. The worst part is that I"m stuck at this accuracy level for sometime now. The difficulty level of these questions is very close to the real thing and unless I improve accuracy, I can forget entry to the magic 7XX club :-(. So, I analyzed my mistakes today and tried to bin them in different broad categories such as gap in fundamental concept, careless mistakes, etc. The mistakes are too basic, but time and again I continue repeating similar mistakes. This is good news because it means I have fewer problems to work on and it"s bad news because I still haven"t learnt from mistakes. Anyways, better late than never.. I hope that this exercise will help me minimize the mistakes.. :-( Here are the mistake categories - 1. Number properties. - Unless stated otherwise, all numbers in GMAT are real numbers. - If given number is integer, don"t forget to consider "0", -ve, and +ve integers. - In problems involving X^Y, always consider the special case when X, Y is 0, 1, -1 - Try out these different values: -2, -1.5 -1, -0.5, 0, 0.5, 1, 1.5, 2. Does time permit to try out so many values? Specially if there are more than one variable? - After spending 1-2 min, you realize that the calculations do not yield the correct result. You have two options. Either to do the exercise once again, or to guess and move on. - Even worse, if you did not read the question stem carefully, you will mark one of the wrong answer choices and move on. Worst, you will not even realize your mistake until you see your score :-( - Bad choice of variables/symbols and you find yourself lost in the equations. Finally, you just guess and move on. Take a deep breath.. think... then proceed. This will probably cost extra 10 sec, but will help a lot. - You think C is the correct answer? Think again!! This has troubled me sooooo many times.
