Time management strategy for individual question

Good question! A few thoughts for you:

1) Since you still have some time to study, step one for you is to figure out how to get faster (without sacrificing accuracy) so that worrying about the clock is less of a factor. One great way to do that is to look at any question that took you more than the average amount of time and ask yourself "what should I have seen in order to have done this one faster?" This is something I'd say is missing from a lot of people's error logs (especially b/c they don't have to be errors - a correct answer in 3 minutes that you could have gotten in 1.5 is something you should definitely work on! Asking yourself that question - what didn't I see at first that ended up being a key to setting it up quickly, avoiding having to go back and re-read the answers, etc. - is a great way to see if you can find patterns in things you should start looking for.

(For example: words like "both," "neither," and "only" in word problems can signal that you should get started on a Venn Diagram; if you can't get started on a geometry problem, often you need to look to draw a diagonal to form a triangle, or try to determine that triangles are similar, etc. On Critical Reasoning, you can spend forever debating answer choices to a Strengthen or Weaken problem if you don't notice the adjective or modifier that makes the conclusion of the argument extra specific and that showcases the gap you need to fill in (S) or exploit (W))

2) Also as you're reviewing those problems, take note of which types of problems, content areas, etc. are the ones you tend to A) spend the most time on while B) having the least success on. And then just know those going into the test so that when your conscience tells you "you're taking too long" you can also add in consciously "shoot, and it's a permutations problem with a restriction I can't figure out how to account for...it's time to make a smart guess and move on b/c I tend to not do too well on these." So much of GMAT pacing is knowing where it's smart to invest that extra time - yeah it'll take another 45 seconds *but* you tend to get them right and the previous 2 minutes is a sunk cost so just finish the job - versus where that extra time won't pay off for you. A 2-minutes-per-question doesn't mean you can't spend more than 2 minutes on any question...but it does mean that if you spend 2:40 on a question you'd better get it right, and you have to account for that 40 seconds somewhere else either by being faster or by knowing when to cut your losses on a problem you're just not going to get right.

3) Make "timed drills" a part of your study regimen - do small sets of problems (5, 10, or 20) with a timer set for the pace you want to keep up (e.g. 10 minutes for 5 quant questions to keep the 2:00/question pace) and use that as an opportunity to get used to what your pace should feel like. You do not want to actively think about your pace per question on test day, or look at the timer after every question. If you're worried about pacing, the last thing you want to do is spend extra time checking a clock or calculating your pace! That just wastes more of the time that you're already worried is in short supply. You want to develop a sense for when a problem is taking too long so that you can have that conversation with yourself ("am I going to get this if I stick with it, or should I move on and bank the time?") without having to consult the clock and do extra math.
