Hi himbha93.
Increasing your GMAT verbal score takes a few key things.
- You have to get what GMAT verbal tests, which is not really whether you know a bunch of facts. It tests your vision, your attention to details, your skill in using logic, and your execution skills.
- You have to learn key concepts. Yes, GMAT verbal is not a test of knowledge. At the same time, to play the GMAT verbal game, you need to know the rules.
- You have to learn some basic strategies, but NOT any shortcuts. Shortcuts will not work.
- You have to train to develop the skills mentioned above.
So, if you have not succeeded in increasing your verbal score, you have to figure out which of the above you have not achieved.
Maybe you have been preparing as if GMAT verbal is a test of knowledge rather than a test of skill.
Maybe you have to better understand concepts.
Maybe the strategies you are using are not sound. (I suspect they are not.)
Maybe you have to do more analysis of questions to develop the vision, attention to detail, and execution skills necessary for rocking GMAT verbal. (I am basically certain that you have to do more.)
My best guess is that there are adjustments that you can make related to all four of the aspects of mastering GMAT verbal mentioned above.
