670 is a great score! Congratulations!
I'll be very proud of myself if I get anywhere between 650 and 720.
Awaiting your detailed debrief. Can you please tell more about your experience in the quant section? What were your quant practice scores and how actual GMAT quant compared to the practice tests such as GMATPrep. I see that you got 44 in quant, so I can relate to your experience much better than to that of quant gurus getting 50-51 in quant.
My quant scores have never been higher than 44-47, so I think your debrief will be very beneficial for quant-challenged people like me
