Hi shamim2k14,
Based on the score breakdowns from your two GMAT prep exams, you are certainly capable of a higher verbal score on the real GMAT. However, prior to retaking your GMAT, you may consider a regimen of focused practice to find and fix your remaining verbal weaknesses, while maintaining or even improving your quant score.
For example, if you are reviewing Critical Reasoning, be sure that you can practice 50 or more questions just from Critical Reasoning: strengthen and weaken the conclusion, resolve the paradox, find the conclusion, must be true, etc. The results of that practice will help you determine your weak areas within that topic. Once you find and fix your weak areas, then move on to the next verbal topic.
Also, to help improve your reading comprehension, I recommend reading publications such as the Economist, the New Yorker, Scientific American, or the Smithsonian so you can get used to reading and analyzing long, sophisticated passages that are well written.
To truly master Sentence Correction, you must develop mastery of grammar rules (parallelism, subject/verb agreement, etc.) and accepted English usage. Concentrate on one topic at a time, such as modification, and practice with as many modification questions as you can find. Only after you feel confident with modification should you move to the next topic. In addition to your dedicated study, notice grammar and usage in your everyday life. Be aware of the things you habitually read, in terms of sentence structure, how phrases are worded, and whether pronouns are easy to understand, to name just a few. Make sure you use proper grammar in your everyday writing as well. Have you put parallel ideas into parallel constructions? Do all of your pronouns refer appropriately to their antecedents? The more you reinforce your study with related activity outside of your study, the greater the likelihood you will master the topics, and have fun doing so!
In regard to quant, you may consider doing some focused practice to stay fresh with the material and also uncover any lingering weak areas. To help diagnose your GMAT quant strengths and weaknesses, I welcome you to take my free
37-question quant diagnostic. After completing the diagnostic, you will be provided with a detailed analysis of your proficiency level of GMAT quant topics, as well as an opportunity to discuss your diagnostic results with me or another
