Targeting Stern, Columbia or Cornell and wanted to apply in the next month, but sat GMAT this week and only got 680. I am consistently strong in Verbal (47) but totally bombed on Quant (37). I have struggled with the Quant the whole way through and got mid 600s in many of the Kaplan CATs (having started at 550) due to weaker quant. I sat the two official prep downloads and got 730 and 720, so was encouraged that the Kaplan ones may be set harder, but struggled on test day. I don't know where to go from here? I obviously need to re-sit, but do I focus on GMAT for the next 6 weeks and then aim for second round applications, or try and write all the admissions essays etc whilst studying and aim for the early November deadlines with a GMAT re-sit early Nov. How important is it for international students to meet the November deadlines?

Also, how do I improve the quant? I have done the Kaplan classroom course, done all their CATs, and their Quiz Bank questions. I understand the syllabus but just freeze when it comes to the problems? What's the secret to getting a major improvement in Quant in 1 month? What are the best materials to use? Is private tutoring worth it?

So many questions, but any advice would be massively appreciated as I am confused as to the best way forward from here...and freaking out just a little. Thanks in advance!!
