this is a great thread because i have this problem. i tend to be so worried that i'm going to be rushed for time at the end that i think i rush a bit. i usually finish the quantitative with about 6-7 minutes still left and verbal with about 10 minutes still left on the clock. if i struggle on a problem, i'll make a best effort but eventually i'll think "more time won't help at this point...just move on" and i'll whittle down the answers, guess, and move on.
i'd like to be on pace to keep about 3-4 minutes of buffer just in case i run into a difficult problem (or problems) at the end and want to devote a little more time but is there an easy way to stay on pace?
on verbal it's also more difficult to gauge because of RC sections.
