Hi Raj.
Generally, the way to increase your GMAT score is to work on one area at a time, basically driving your score up point by point.
Looking at your ESR, you can get a pretty clear idea of the areas to focus on by noticing in which areas you got lower percentages of questions correct. Since you had to rush at the end of each section, the information provided by your ESR may not be ideal for determining which areas to work on, because you may have missed questions of some types only because you rushed through them. Still, I think it's a good bet that, by working on topics such as Geometry in quant and Critical Reasoning and meaning-focused Sentence Correction questions in verbal, you'll drive your score higher and hit your score goal.
Specifically regarding the fact that were pressed for time in both the quant section and the verbal section, speed comes with skill, and if you can believe it, skill tends to come from slowing down when practicing. In other words, particularly in verbal, but also in quant, you'll develop more skill by doing your practice untimed and seeking to fully understand every aspect of a question before you choose an answer choice than you will by doing your practice timed and reviewing questions in depth only after you have selected choices and seen whether the choices you selected were correct or incorrect. So, do your practice untimed and shoot for understanding and close to 100 percent accuracy.
Also, since you are shooting for an especially high score, you should work on getting questions correct in long streaks; 15 correct in a row would be good. 20 correct in a row would be even better.
