Hi akanksha2508,
I'd still like to know more about each of your individual Official Scores, including the exact Quant and Verbal Scaled Scores for each.
The minor fluctuations in your score notwithstanding, these Official Scores are all 'clustered' in the mid-to-high-500s. The results show that you're still 'responding' to the GMAT in relatively the same ways as you did years ago (before you really studied). As such, your 'default' approach to the Test will likely continue to earn you a score in the 500s. To score 700+, you're likely going to need another 2-3 months of consistent, guided study. During that time, you'll need to learn/practice some new Tactics and work to eliminate all of the 'bad habits' that you've developed over the years (and replace them with new 'good habits'). Thankfully, the GMAT is the same consistent, predictable Exam that it's always been. Unfortunately, one month is probably not going to be enough time for you to hit your score goal.
1) What is your exact Test Date?
2) Do you have flexibility to push that Test Date back?
GMAT assassins aren't born, they're made,
