I keep reading on the forums that leaving a question blank hurts one's score more than guessing incorrectly hurts one's score. I just want to clarify that this argument is not factoring in the likelihood of guessing correctly as the inherent reason for arguing that guessing is better?
I ask this question because I took the GMAT this weekend and made a 760 (Q47, V48). I left the last question on Quant blank, though (felt confident that I got the 2nd to last question correct)...time then expired while I was reading the final question before I could make an educated guess. So I am wondering if I hurt myself more by running out of time and leaving it blank than by not guessing incorrectly? I'm also wondering to what extent I hurt myself -- would my Quant score possibly have gone up to 48 and my overall 770 (according to http://www.800score.com/score2.html
a 48/48 is a 770)?
