Hi VGH84,
I’m sorry to hear about what has been happening with your GMAT prep, but I’m happy to help get you on the right track. Unfortunately, you won’t be able to score 700 in the next two weeks, so, to start, you may consider pushing your exam to a later date.
Given that your GMAT score appears to have plateaued between 570 and 610, it appears that you have started taking practice exams before truly mastering GMAT quant and verbal. I understand that you want the put the GMAT behind you as soon as possible; however, you are going to have to dig in and follow a patient yet structured approach to truly improve your GMAT score.
Moving forward, you are going to need a study plan that allows you to learn linearly, such that you can slowly build GMAT mastery of one topic at a time. Within each topic, begin with the foundations and progress toward more advanced topics. 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 developing your conceptual knowledge, you will want to practice by answering 50 or more questions just from number properties. As you practice, do a thorough analysis of each question that you don't get right. If you get a remainder question wrong, ask yourself why you got it wrong. 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.
Follow a similar routine for verbal. Let’s say you are learning about Critical Reasoning. Be sure that you first learn the necessary concepts of CR questions and then practice a large number of CR questions: strengthen and weaken the argument, resolve the paradox, find the conclusion, must be true, etc. As you go through the questions, do a thorough analysis of each question that you don't get correct. If you missed a weaken question, ask yourself why you didn't get it right. Did you make a careless mistake? Did you not recognize what the question was asking? Did you skip over a key detail in an answer choice? Getting GMAT verbal questions right is a matter of what you know, what you see, and what you do. So, any time that you don't get one right, you can seek to identify what, if anything, you would have needed to know in order to get the right answer, what you had to see that you didn't see, and what you could have done differently to arrive at the correct answer.
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 at least around 90 percent accuracy in your training. If you get 100 percent of some sets correct, even better.
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.
