Hi sudhirgupta93,
From what you've described, it sounds like almost all of your CAT scores include 'inflated' Verbal results (since there were so many 'repeat' questions that you already knew the answers to). This recent score (with the V31), might be the one accurate measure that you have - and we can't assume that those other score results are accurate. While your Quant scores seem consistently strong, you would have to make some significant improvements to raise a V31 up to a high enough level to hit 740+ on Test Day. Unfortunately, with less than a week to go, that might be too difficult a task to be considered a realistic goal.
Since it's now less than 7 days until your Exam, you should plan to take the GMAT on Friday as planned.
1) After reviewing the V31, what types of questions were you having the most difficulty with?
2) If you don't score 740+ on Friday, how will your plans change?
3) When are you planning to apply to Business School?
4) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
