what do you think? This is the data, but I don't see your analysis. :)
I'll tell you what I think, but next time you're going to have to tell me what you think first - you have to be able to analyze this stuff yourself, too.
Clearly, you have a PS timing problem, and that's hurting you on both PS and DS problems. You had 9 too fast and wrong questions that you sacrificed to spend extra time on only 7 other problems - and you got 6 of those ones wrong anyway!
This pattern is quite common, so don't feel bad. :) Know that this is the pattern: you choose to spend too long on questions that are too hard (and so you're likely to get them wrong anyway), and then you speed up on even more questions (you sped up on more than just those 9), and then you get a bunch of the "too fast" Qs wrong at least partly due to rushing.
Choose to cut the too-hard problems off instead. That gives you normal time to spend on other questions that you can actually get right... if you don't make yourself have to rush.
Read this timing article:

If you don't have one already, buy yourself a stopwatch with lap timing capability. When you go to do a set of problems, start the stopwatch but turn it over so you can't see the time. Every time you think you're one minute into a new problem, push the lap button. When you're done with that problem, push the lap button again, then repeat the process for the next problem. When you're done with the set, see how good you were - and whether you tend to over or underestimate. Get yourself to the point where you're within 15 seconds either way on a regular basis (that is, you can generally predict between 45 sec and 1min 15 sec). Also check your timing for the entire question, of course.
Now, how do you use that when doing problems? If you're not on track by one minute, make an educated guess** and move on. (The general idea is that if you're not on track by the halfway mark, you're unlikely to figure out what's holding you back AND have time to do the whole problem in the 1 min you have left.)
** This also requires you to know HOW to make an educated guess depending upon the type of problem and the content being tested. So that's something else to add to your study: how to make educated guesses on different kinds of problems.
(Also, note, the above is for quant - verbal's a bit different.)
Here are a couple of articles on educated guessing:
http://www.beatthegmat.com/mba/2010/07/ ... s-on-quanthttp://www.manhattangmat.com/articles/e ... verbal.cfmThe good news is: your timing problems are significant enough that you will see a score boost once you fix them. The bad news: if you don't fix the timing problems, it'll be tough for your score to go up much more - that's really why you're hitting a plateau.
So off to the races - fix those timing problems! The short solution is just cutting yourself off on those too hard problems. But also make sure that you know how to get right the too-fast ones that you missed. If you made careless mistakes, set up some better habits / patterns (for while you do the work) to minimize repeats.
Then, later, you can see whether you want to try to learn more for those too-long-and-wrong problems. But for now, just stop them from bringing you down by getting them wrong faster!
