Hello Akash,
Since you are decent enough in Quant , i would like to share my insight after going through your ESR.
P.S.- I am not even close to expert. You may follow or adopt any/none/all advice of mine at your own discretion!
So your verbal score is 12. Your ESR reflects that you have a very weak CR and SC. It does not mean that your RC is good (sorry to be blunt). 26 percentile in RC is a very low score. But there are always areas of improvement.
Now Assuming, you may not have devoted any good preparation time in your Verbal(since you already mentioned in your clarification of Mock scores) i would like to share these tips. I am too a Gmat aspirant and i am gonna retake again in few weeks.
CR- CR is a test of logic and really stressful if you do not know what is to be done or how to approach. My suggestion would be. Firstly , go through any CR book( Preferably ( Powerscore/Manhattan/ or few pdfs available in gmat club of various expers sharing CR notes and how to approach). However any book you choose, be sure to go through each and every section in a very detailed way. I mentioned above books not because i recommend those books but because there should be a guiding system which you can adapt to in the beginning and that will make you comofortable. Take one thing at a time. Fix a week schedule where you will learn only (lets say Assumption topic of CR). Rigorously find out about assumption as in " what is Assumption". What are the roles of assumptions. How it affects the argument. How can the conclusion be determined , What are the premises etc etc. Try to understand thoroughly. Take it slow , really slow. And after you finish assumption section, its time for practicing assumption questions. Dont just jump at 600 or 700 level questions. Start from very basic of 500 level questions. You will find them plenty in Gmat club forum. Do time the question when you practice it , however just forget the point that you have timed it. I am saying this because of two reasons. First by timing yourself, you will be able to track the progress when you reach a little comfort zone by comparing the "then" timed questions and "now" timed questions. Second, when you time yourself and you kinda ignore that fact , then its a good sign because you are not allowing yourself to distract which will prove very beneficial when you take the exam(Trust me:)) . After you finish 500 level , see what is your efficiency and accuracy. Ok , when you get any question wrong, try to find out why you got wrong. Is it because you did not understand the Argument or was not able to find any conclusion or were the answer choices too clumsy to relate , or were you not able to apply how it is affecting the argument. Correct those mistakes and reapply . I am sure you will sail through next time. Only when you are comfortable in 500 level move on to 600 level question and then 700. As a benchmark , % of accuracy in 500 should be 100 and in 600 more than 90 and then in 700 more than 50. Be sure to move on to next section when you could achieve at least 90% of desired ideal accuracy
Now repeat this exercise for every section such as Strengthen , weaken , Evaluate , Bold faced, Inference etc sections of CR.
SC: When it comes to SC, i would highly recommend
egmat videos of SC. Try to get those videos. If finance is a constraint, then there are many articles posted by
egmat in gmat club forum , you can go through them. I also recommend Sc book by Manhattan. That book might be one of the greatest contribution by Ron. Hopefully you will gain something from the book. there are very limited concepts in SC. Subject verb, Modifiers, Parallelism, Comparison, Pronouns, Tenses/Verbs etc, Go through each section one at a time and repeat the CR process i mentioned above. The process is same. Practice the questions and then move on to next section when you are comfortable and confident enough. One thing to note in SC is that you may struggle a lot in the beginning but as you adapt the process of elimination after applying concepts, you will feel much more comfortable. Make sure that when you choose answers , you chose it after knowing the fact that the answer you chose should be the one . And try to read Experts comments/clarifications as how they approach the question.
RC- when it comes to RC , i doubt that there are any specific rules that will apply to RC . Its a matter of reading and comprehending and if you are terrible at it , then it will surely take time. Take it slow,, really slow. Read the passage first and then understand and if you want to take notes , dont hesitate. Later when you are comfortable, you will gradually retain all information. Make sure that you read RC at a slow pace and try to find out if you are not able to infer or decipher the meaning because of the structure or topic or something else. After making sure that you understood the RC , attempt the questions. Try to eliminate the incorrect first by loudly speaking in your mind that " this is incorrect because-----_. This will help you. repeat this process , again and again
Make sure that you read daily 3 RCs and solve them. Do not get disappointed if all of them goes wrong. Believe me, it takes time to improve but when you improve, the learning graph is often exponential.
Hopefully after going through this process, you will be able to achieve your dream score. And dont forget to thank me then :P
Remember GMAT is not a test of mugging, intellectualism . Its much more than that. Its a test of strategy , time management and logic and ability
Please ignore some typos and grammar errors
All the best
