"Problem" with Quant

1. The trick isn't to 'go faster', most of the time. On the GMAT, if you try to just do the same thing, but do it faster, you'll trip over your own feet. You'll end up making foolish mistakes! A good saying to remember is 'slow is smooth and smooth is fast'. Instead, focus on:
- doing the problem differently (understanding it more clearly without rereading it multiple times; getting the right strategy on your first attempt; using a totally different strategy; doing the problem more efficiently, with fewer steps)
- identifying problems that are above your goal level (so in your case, 750+ level problems) and strategically guessing to save time for other problems. Missing a very hard problem has very little impact on your score, so if you can correctly identify super tough problems and avoid wasting time on them, you'll have time to spend on the stuff you could get right. Start with the 1/3 of your missed questions that you didn't get right when redoing... many of those, you should've guessed on quickly.

2. What this means depends on what you're doing when you redo the problems, and why you missed them. Are you missing them because you're making silly math mistakes? Are you missing them because you're misreading them? Because you can't remember what math or what strategy to use in the heat of the moment? It also depends on whether you're using a timer when you redo the problems, whether you're doing them as part of a set or one by one (doing just one problem alone is a lot less stressful), etc.
