Hi MRIDUL,
You've named some competitive Schools, so scoring at a higher level on the GMAT is a must. Since you're a computer science major, I have to assume that you know how to calculate an average and determine the median of a group of numbers. As such, *wanting* a 710+ GMAT Score is NOT the same as *needing* a 710+ GMAT score - this is all meant to say that you actually need a score that is 'in range' of your Schools, not necessarily one that is at/above the median.
Based on the CAT scores you've listed, you need to work on BOTH the Quant and Verbal sections, so you need more than just new Verbal resources. Most GMAT Companies offer some type of free materials (practice problems, Trial Accounts, videos, etc.) that you can use to 'test out' a product before you buy it. We have a variety of those resources at out site (
www.empowergmat.com). I suggest that you take advantage of all of them, then choose the one that best matches your personality, timeline and budget.
If you have any additional question, then just let me know.
GMAT assassins aren't born, they're made,
