Hi priyatamsoni7,
I’m glad you reached out, and I’m happy to help. The good news is that you have made some solid improvement (from 560 to 630) despite studying with only the
OG and practice exams. However, to improve to a 740, you probably need to make some changes to your study routine. Looking at your current study routine, it appears that your prep is 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 those questions are based. Thus, moving forward, consider adjusting your study plan such that it allows for linear learning. Specifically, consider using a resource that allows you FIRST to learn the concepts and strategies related to GMAT quant and verbal and SECOND to practice with a large number of realistic questions.
For example, if you are learning about Number Properties, you should develop as much conceptual knowledge about Number Properties as possible. In other words, your goal will be to completely understand properties of factorials, perfect squares, quadratic patterns, LCM, GCF, units digit patterns, divisibility, and remainders, to name a few concepts. After carefully reviewing the conceptual underpinnings of how to answer Number Properties questions, practice by answering 50 or more questions just from Number Properties. When you do dozens of questions of the same type one after the other, you learn just what it takes to get questions of that type correct consistently. If you aren't getting close to 90 percent of questions of a certain type correct, go back and seek to better understand how that type of question works, and then do more questions of that type until you get to around at least 90 percent accuracy in your training. If you get 100 percent of some sets correct, even better. Number Properties is just one example; follow this process for all quant topics.
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 do such 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.
Follow a similar routine for verbal. For example, let’s say you start by learning about Critical Reasoning. Your first goal is to fully master the individual Critical Reasoning topics: Strengthen the Argument, Weaken the Argument, Resolve the Paradox, etc. As you learn about each Critical Reasoning question type, do focused practice so that you can track your skill in answering each type of question. If, for example, you get a weakening question wrong, 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 instead 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 thereby comprehend the main idea of a paragraph. As you read a paragraph, 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 Reading Comprehension answers to better determine why you tend to get a particular question type wrong, and then improve upon your weaknesses. Keep in mind that GMAT Reading Comprehension passages are not meant to be easy to read. So, to better prepare yourself to analyze 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, it is likely that you will have to work on all three of those aspects, and it is also likely that your Sentence Correction performance has not improved because you have not been working on all three of those aspects. Let's discuss each of those aspects and how you can work on them.
Regarding what you know, first and foremost, you MUST know your grammar rules. Let's be clear, though: GMAT Sentence Correction is not really a test of knowledge of grammar rules. The reason for learning the 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. Likely, the main reason that Sentence Correction has not "clicked" for you is that you have not put enough work into developing your skill in seeing what is going on in the various versions of the sentence that can be created with the answer choices. 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 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 will then want to practice with questions that test you on skills from multiple Sentence Correction topics.

Feel free to reach out with any further questions.
Thank you for the thorough explanation. I really appreciate your efforts. While going through the above mentioned steps to master on each section, i was able to find a few similarities between my strategy and yours'. But yes of-course, there are some areas where i have to focus on. Here are some points which i find similar and areas that need improvements:
1. Quants: As you said, i need to understand concepts more thoroughly. Yes i agree to that and in my strategies i follow some steps which you have mentioned above. My strategy includes find the mistakes, try to understand the question, try to simplify the equation, try to put values etc. I usually take a set of random questions from all the topics and start solving them. But i think i should practice some set of questions from particular topics and then start doing mixed sets. Sometimes i get confused whether to put values or to solve the equation. Could you please suggest me something on this.
2. Reading comprehension: Whenever i come across an RC passage, i start reading the passage actively and try to understand the passage structure. I try to find the relation between paragraphs, figure out the main idea, tone, contrast word to understand the flow of the passage. I never select the answer choice but eliminate the wrong ones. Few weeks back i was facing issue in inference questions. I used to get confused which answer choice is correct as i used to end up eliminating three answer choices but be left with two. Then i started focusing more on my reading part. After doing several questions, i was able to figure out the particular location of the answer from a particular paragraph from which i need to infer. But i would say sometimes i still find the inference question a bit difficult then the other ones. I think i should do more inference questions and should analyse each question properly.
3. Critical Reasoning: I think i am somewhat good at CR than i am at the other sections. I usually read the argument first and figure out the conclusion. In assumption question i try to fill the missing gap between premise and the conclusion. In strengthen/weaken question i try to find the extra information that strengthen/weaken the argument. In inference question i strike out the answer choice which is totally irrelevant and try to find an answer choice that can be inferred from the mentioned premise and conclusion relationship. In boldface question, i remember the keywords for premise and conclusion and on the basis of that i eliminate the answer choices. In paradox question, i make three buckets. Bucket #1: The information which helps to describe the expected conclusion. Bucket #2: The information which helps to describe the unexpected conclusion. Bucket #3: Irrelevant information. After categorising the answer choices into three buckets, i pick the answer choice.
4. Sentence correction: I am very bad at memorising idioms but after doing so many questions i am able remember a good number of idioms. I usually face difficulties in understanding the sentence, meaning clarity and some idioms which i have never come across. In sentence correction, i make 3:2 ratio in answer choices by scanning them. Then i decide which part is correct and after that i again start scanning the remaining answer choices and try to figure out the correct answer. In my experience whenever i answered any question wrong there was 2 choices left with minor differences. I think i should focus more on meaning clarity, should try to understand the sentence clearly and try to remember few more idioms.
I have mentioned above my strategies and opinions on improvements. Please correct me if i am wrong at my reasoning. And one more question i have, is i can work on my basics but it is difficult to find realistic questions as i have already done so many practice questions. Could you please suggest me a good source to get these good questions.
