I didnt finish 2 questions on the quant portion - anyone know the approx value in pts I lost by not even guessing?
Go through post on pacing yourself: http://www.veritasprep.com/blog/2009/10 ... e-week-48/
As for your question, let me give you an extract from this post:
"The creators of the GMAT confirm that there is a steep penalty for failing to answer a question – estimated at 5 percentile points for simply leaving one question unanswered. You must at least levy an answer to each question, but for pacing purposes, you may want to consider that having just enough time to guess on question 37 is at least acceptable, and having enough time to thoroughly complete it is ideal."
So you are looking at apprx 10 percentile points which means that if you got 80 percentile in Quant, 90 percentile was a matter of 30 secs. Of course, this is very approximate depending on the level of last 2 questions and your accuracy in them.
