Hey Varun,
The key thing you need before you embark on retake prep is the answer to the WHY question.
WHY are you getting Verbal questions wrong?
More often than not, after extensive studying, the easiest things to fix are process problems -- how you're tackling each question step by step.
For example
In SC, are you first eliminating answers in SC before trying to pick the right answer?
In CR, are you clearly restating to yourself the argument before trying to chose an answer?
In RC, are you capturing purpose and tone on a paragraph by paragraph basis?
These a few examples of many Verbal strategies that will help you to quickly fill your score GAP.
