Hi pulkitsahani.
There are multiple aspects of correctly answering verbal questions.
One of them is knowing basics, such as rules or what you have to do when you see a certain type of CR question.
Another aspect is being skilled at arriving at correct answers.
While the first aspect is clearly part of the second aspect, knowing basics is clearly not sufficient to get you to the correct answers to more challenging verbal questions. So, what else is necessary?
There are two things that you have to further develop.
- Skill in clearly defining why choices are incorrect or correct
If, when you go back to a question, you immediately see why the correct answer that you didn't choose is correct, it must be the case that, when you answered the question you didn't have a sufficiently clear reason for choosing the choice you chose. So, to score higher in verbal, you have to further develop your skill in applying the basic concepts that you understand to clearly defining why choices are incorrect or correct.
Interestingly, your becoming better at clearly defining why choices are incorrect or correct will not only result in your choosing correct answers more consistently but also will result in your speeding up, because it will result in a reduction of the amount of time you spend circling between choices because you haven't defined the differences between them.
- Execution skills
Another key aspect of correctly answering verbal questions is execution. So, you have to do things like making sure that you consider the non-underlined portions of sentences, correctly identifying conclusions, and making sure that you read passages and choices in their entirety, so that you don't get tripped up by details that you had missed. You can know all about how to answer verbal questions, but you will answer them correctly consistently only if you execute well.
So, here's my suggestion. To develop these aspects of your verbal skills over the next week, toward the beginning of the week, answer many verbal questions very slowly. Take your time carefully define why every incorrect choice is incorrect and every correct choice is correct. At the beginning of the week, you may spend ten minutes or more per question. You have to get used to applying what you know to clearly defining why choices are incorrect or correct.
As you do this, seek to answer basically all the questions correctly. You have to develop execution skills. What you know is not enough to get you a high score in verbal. What you do is very important as well. So, practice slowly and seek to execute flawlessly. If you miss a question, consider what about your execution could have been better.
Then, toward the end of the week, start doing some timed practice, to get into the mode of using in timed conditions the skills you have developed.
Whether a week will be sufficient time for you to develop the verbal skills you need in order to hit your score goal is not clear. Further, it may be that, while you get the basics, you need to understand more sophisticated verbal concepts in order to correctly answer 700 level questions more consistently.
At the same time, using slow, careful practice to develop key aspects of your verbal skill set is key to scoring high in verbal, and, by taking this approach over the next week, you may develop your verbal skills sufficiently for hitting your goal.
