Hi sanathadiga,
I’m glad you reached out, and I’m happy to help. So, there are three things that stand out from your debrief that I believe led to your performance on test day:
1) As HanoiGMATtutor mentioned, taking 10 practice exams in 21 days is not a good idea. Sure, you scored high on many of those exams, but you are not able to make the most of practice tests when taking them every other day, right? Practice exams need to be spread out such that you can a) fully examine each exam to find and fix weaknesses and b) study weak topics in between each exam so that you ensure an improvement from one exam to the next.
2) During your prep, you say that you studied for 3 hours every day, stopped traveling and hanging out with friends, and put all your efforts into cracking the exam. Why do those things stand out to me? Well, it’s clear that you put WAY TOO MUCH pressure on yourself to succeed on the GMAT. Thus, in addition to over-testing and inefficiently studying (I’ll get to that next), you closed off your entire life for 3 months and only focused on the GMAT. It’s no surprise that on test day, the immense pressure you had been putting on yourself finally came to a head and affected your performance. Remember, there is a big difference between actively, steadfastly preparing for the GMAT and over-preparing to the point where you never give yourself a moment to relax. Moving forward, try to incorporate GMAT studying into your normal life. Certainly, that doesn’t mean socializing every night; however, it’s important to spend time with family and friends and do things that make you happy, so you’re not thinking about the GMAT every hour of every day. Too much stress can negatively impact both your knowledge retention when studying and your performance on test day.
3) You previous study routine consisted of completing the
OG and taking practice exams. Thus, you never gave yourself a chance to really learn the content on the GMAT, because your prep centered on doing practice questions. While engaging in practice is a necessary part of improving your GMAT skills, such practice is only beneficial after you have studied the necessary topics on which practice questions are based. Moving forward, consider adjusting your study plan to allow for linear learning. Specifically, consider using a resource that allows you FIRST to learn the concepts and strategies related to quant and verbal and SECOND to practice with a large number of realistic questions.
Now, as far as HOW to improve your GMAT skills before your retake, you need to follow a more thorough study plan. Say you begin studying Critical Reasoning. You need to ensure that you fully understand the essence of the various Critical Reasoning question types. Do you know the importance of an assumption within an argument? Can you easily spot a conclusion? Do you know how to resolve a paradox? Do you know how to properly evaluate cause and effect? Do you know how to properly weaken or strengthen an argument? These are just a few examples; you really need to take a deep dive into the individual Critical Reasoning topics such that you develop the necessary skills to properly attack any Critical Reasoning questions that you encounter.
As you learn each Critical Reasoning problem type, do focused practice so that you can track your skill in answering each type. If, for example, you incorrectly answered a Weaken the Argument question, ask yourself why. Did you make a careless mistake? Did you not recognize the specific question type? Were you doing too much analysis in your head? Did you skip over a keyword in an answer choice? You must thoroughly analyze your mistakes and seek to turn weaknesses into strengths by focusing on the question types you dread seeing and the questions you take a long time to answer correctly.
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.
Sentence Correction is a bit of a different animal compared to Reading Comprehension and Critical Reasoning. There are three aspects to getting correct answers to GMAT Sentence Correction questions: what you know, such as grammar rules, what you see, such as violations of grammar rules and the logic of sentence structure, and what you do, such as carefully considering each answer choice in the context of the non-underlined portion of the sentence. To drive up your Sentence Correction score, you likely will have to work on all three of those aspects. Furthermore, your Sentence Correction performance likely has not improved because you have not been working on all three of those aspects.
Regarding what you know, first and foremost, you MUST know your grammar rules. Let's be clear, though: GMAT Sentence Correction is not just a test of knowledge of grammar rules. The reason for learning grammar rules is so that you can determine what sentences convey and whether sentences are well-constructed. In fact, in many cases, incorrect answers to Sentence Correction questions are grammatically flawless. Thus, often your task is to use your knowledge of grammar rules to determine which answer choice creates the most logical sentence meaning and structure.
This determination of whether sentences are well-constructed and logical is the second aspect of finding correct answers to Sentence Correction questions, what you see. To develop this skill, you probably have to slow way down. You won't develop this skill by spending under two minutes per question. For a while, anyway, you have to spend time with each question, maybe even ten or fifteen minutes on one question sometimes, analyzing every answer choice until you see the details that you have to see in order to choose the correct answer. As you go through the answer choices, consider the meaning conveyed by each version of the sentence. Does the meaning make sense? Even if you can tell what the version is SUPPOSED to convey, does the version really convey that meaning? Is there a verb to go with the subject? Do all pronouns clearly refer to nouns? By slowing way down and looking for these details, you learn to see what you have to see in order to clearly understand which answer to a Sentence Correction question is correct.
There is only one correct answer to any Sentence Correction question, there are clear reasons why that choice is correct and the others are not, and those reasons are not that the correct version simply "sounds right." In fact, the correct version often sounds a little off at first. That correct answers may sound a little off is not surprising. If the correct answer were always the one that sounded right, then most people most of the time would get Sentence Correction questions correct, without really knowing why the wrong answers were wrong and the correct answers were correct. So, you have to go beyond choosing what "sounds right" and learn to clearly see the logical reasons why one choice is better than all of the others.
As for the third aspect of getting Sentence Correction questions correct, what you do, the main thing that you have to do is be very careful. The main thing that you have to do is be very careful. You have to make sure that you are truly considering the structures of sentences and the meanings conveyed rather than allowing yourself to be tricked into choosing trap answers that sound right but don't convey meanings that make sense. You also have to make sure that you put some real energy into finding the correct answers. Finding the correct answer to a Sentence Correction question may take bouncing from choice to choice repeatedly until you start to see the differences between the choices that make all choices wrong except for one. Often, when you first look at the choices, only one or two seem obviously incorrect. It may take time for you to see what you have to see. Getting the right answers takes a certain work ethic. You have to be determined to see the differences and to figure out the precise reasons that one choice is correct.
To improve what you do when you answer Sentence Correction questions, seek to become aware of how you are going about answering them. Are you being careful and looking for logic and details, or are you quickly eliminating choices that sound a little off and then choosing the best of the rest? If you choose an incorrect answer, consider what you did that resulted in your arriving at that answer and what you could do differently in order to arrive at correct answers more consistently. Furthermore, see how many questions you can get correct in a row as you practice. If you break your streak by missing one, consider what you could have done differently to extend your streak.
As with your Critical Reasoning and Reading Comprehension regimens, after learning a particular Sentence Correction topic, engage in focused practice with 30 questions or more that involve that topic. As your Sentence Correction skills improve, you’ll then want to practice with questions that test you on skills from multiple SC topics.
Although your quant is stronger, you should 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. When you are working on learning to answer questions of a particular type, start off taking your time, and then seek to speed up as you get more comfortable answering questions of that type. 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.
In order to follow the path described above, you may need some new verbal and quant materials, so take a look at the GMAT Club reviews for the

But the score remained same. I have bought ESR , but I guess it will be available only after 72 his for access. So I shall wait. SC is probably my weakness , but I am not sure about anything any more now.
