Hi ramalcha,
I’m glad you reached out, and I’m happy to help. First off, YES, reschedule your exam. Since you have plenty of time before your applications are due (SEP 2019), there is no point in trying to rush your GMAT, right?
One thing that jumps out at me is the many practice exams you’ve taken despite consistently scoring well under your 750+ goal score. GMAT practice tests best serve two main purposes. The first purpose is to provide diagnostic information. In other words, by taking a practice test, you can get a sense of what types of GMAT questions you’re comfortable answering and arrive at a reasonable estimation of how you would score on the GMAT at that point in time. The second purpose is, naturally, to provide a way to practice taking the GMAT and handling its various challenges, such as time pressure and the varying difficulty of the questions presented.
People often misuse practice tests as primary learning tools. You may have seen posts that go something like the following: A person with a score goal of 740 has been preparing for six weeks, has already taken all six of the official practice tests, and is wondering why her scores have been 600, 590, 570, 610, 600, and 560. In such a case, the person likely has been using practice tests as primary learning tools, meaning that taking practice tests has been much of, or possibly most of, what she has been doing to drive up her score.
Can practice tests be valuable tools for learning and continued score improvement? Yes, of course, if they are used properly and at optimal times in your preparation. However, practice tests should not be used as primary learning vehicles, because practice tests don’t really provide the kind of practice that you need to increase your score. To improve your score, you need to learn the basics of answering various types of GMAT questions, and then practice applying what you have learned by carefully answering practice questions in order to learn to answer them correctly. When you first learn how to answer a particular type of question, answering that type of question correctly can easily take way longer than the two minutes or so per question that you are allotted when taking the GMAT (or a practice test). Two minutes per question can fly by, and if you want to finish the sections of the test on time, in many cases, regardless of whether you have figured out how to answer a question, you may have to just answer and move on. So, while taking a practice test can be a great way to work on your overall approach to taking the GMAT, taking a practice test is not a great way to practice getting right answers to various types of questions. To effectively prepare for the GMAT, you have to practice answering questions of each type without the time constraints of the test and work up to a point at which you can answer questions of each type in around two minutes. When you take multiple practice tests early in your prep, the tests simply underscore exactly what you already know: you need to learn more content and develop more skills to hit your score goal. Why spend three hours taking a practice test just to learn what you already know, wasting a valuable learning tool in the process?
Of course, you can benefit from taking one diagnostic practice test early in your preparation. Furthermore, once you’ve done substantial preparation and mastered much of the content tested on the GMAT, when you sit for practice tests, they will actually show, to some degree, lingering weak areas that require further study. I say “to some degree” because although practice tests provide a pretty good approximation of how a person would score on the GMAT at a particular point in time, because the sample size of questions on any practice test is rather small (31 quant questions and 36 verbal questions), practice tests don’t do a very good job of pinpointing specific areas of weakness. For example, let’s assume that of the 31 quant questions on a given practice test, you encounter one Rate-Time-Distance question and get it wrong. Should you conclude that you need extensive work on Rate-Time-Distance questions? Of course not. Similarly, what if you correctly answered the Rate-Time-Distance question? Are you good to go on those questions? Maybe. But maybe not. In fact, let’s assume that you took six practice tests, saw a total of six Rate-Time-Distance questions, and correctly answered them all. Can you conclude that you’re solid on Rate-Time-Distance questions? Probably not. One thing that makes the GMAT challenging is the vast potential for variation in the questions. There are hundreds -- maybe thousands -- of variations of Rate-Time-Distance questions that can appear on the test. So, correctly answering five or six (or ten) Rate-Time-Distance questions doesn’t really tell you much. You must take care not to over-infer based on practice tests alone.
To truly improve your GMAT quant and verbal skills, rather than taking practice exams and reviewing your answers, you need to follow a thorough and linear study plan that allows you to slowly build mastery of one GMAT topic prior to moving on to the next. Within each topic, begin with the foundations and progress toward more advanced concepts. Since you are seem to be struggling the most in Reading Comprehension and quant, I’m happy to provide some specific advice on how to improve in those areas.
When practicing Reading Comprehension, you need to develop a reading strategy that is both efficient and thorough. Reading too fast and not understanding what you have read are equally as harmful as reading too slow and using up too much time. When attacking Reading Comprehension passages, you must have one clear goal in mind: to understand the context of what you are reading. However, you must do so efficiently, so you need to avoid getting bogged down in the details of each paragraph and focus on understanding the main point of each paragraph. That being said, do not fall into the trap of thinking that you can just read the intro and the conclusion and comprehend the main idea of a paragraph. As you are reading a paragraph, also consider how the context of the paragraph relates to previous paragraphs, so you can continue developing your overall understanding of the passage. Furthermore, as you practice Reading Comprehension, focus on the exact types of questions with which you struggle: Find the Main Idea, Inference, Author’s Tone, etc. As with Critical Reasoning, analyze your incorrect answers to better determine why you tend to get a particular question type wrong, and then improve upon your weaknesses. You can perfect your reading strategy with a lot of practice, but keep in mind that GMAT Reading Comprehension passages are not meant to be stimulating, so to better prepare yourself to tackle such passages, read magazines with similar content and style, such as the Economist, Scientific American, and Smithsonian.
Although your quant is stronger, you can follow a similar process for that section. For example, if you are reviewing Number Properties, be sure that you practice 50 or more questions just from Number Properties: LCM, GCF, units digit patterns, divisibility, remainders, etc. As you practice, do a thorough analysis of each question that you don't get right. If you got a remainder question wrong, ask yourself why. Did you make a careless mistake? Did you not properly apply the remainder formula? Was there a concept you did not understand in the question? By carefully analyzing your mistakes, you will be able to efficiently fix your weaknesses and in turn improve your GMAT quant skills. Number Properties is just one example; follow this process for all quant topics.
Each time you strengthen your understanding of a topic and your skill in answering questions of a particular type, you increase your odds of hitting your score goal. You know that there are types of questions that you are happy to see and types that you would rather not see, and types of questions that you take a long time to answer correctly. Learn to more effectively answer the types of questions that you would rather not see, and make them into your favorite types. Learn to correctly answer in two minutes or less questions that you currently take five minutes to answer. By finding, say, a dozen weaker quant areas and turning them into strong areas, you will make great progress toward hitting your quant score goal. If a dozen areas turn out not to be enough, strengthen some more areas.
So, work on accuracy and generally finding correct answers, work on specific weaker areas one by one to make them strong areas, and when you take a practice GMAT or the real thing, take all the time per question available to do your absolute best to get right answers consistently. The GMAT is essentially a game of seeing how many right answers you can get in the time allotted. Approach the test with that conception in mind, and focus intently on the question in front of you with one goal in mind: getting a CORRECT answer.
