Target 770+, last month of prep

I'll echo what Ajitesh says above - in your diagnostic test history, you have only one reliable data point, and that's the 760 on your GMATPrep test. That's a very encouraging data point! But it's possible that you're really a 740 test taker who had a lucky test, or a 780 test taker who had an unlucky test, and if you wanted to more accurately assess your level, you'd want to take another GMATPrep or two and interpolate your results.

That would actually be a good thing to do soon, because it's a bit difficult to give good advice based only on that one score. If you took another test, and your Quant score was any lower than Q50, I'd suggest carefully analysing your errors, reviewing any theory you might need to review, and working on higher level Quant problems until you consistently score a Q50 (or Q51). I say that because that is probably very achievable. But if you're a consistent Q50, it's worth bearing in mind that the jump from Q50 to Q51 is probably the hardest one-point jump you can make on the GMAT. You not only need to eliminate every careless error, but you also need to be able to see, under test conditions, how to solve essentially every problem (including problems that won't resemble anything you've likely seen before). If you're a consistent Q50, it might be more rewarding to emphasize Verbal, where learning even to solve one more problem correctly on a test is going to add a point to your V score.

If you do take another official test, and can post the result here, I think you'll get more reliable advice, but the 760 does suggest that a 770 is within reach. Good luck!

Kindly also look at the errors when you are getting score less than 700 in your mocks. That will help.

Thank you for the advice!
Ian: I will do another GMAT prep CAT later this week and post my result here.

Do any of you still remember your GMAT Club quant CAT scores? I'd like to have a benchmark
