I'm sorry that this test is such a struggle! If it helps at all: You are not alone.
First, if you took our complete course, then you're eligible for one free Post-Exam Assessment (if you haven't done it already). This is a meeting with an instructor to debrief from test day and come up with a plan to re-take the test. If this applies to you (or if you think it might), please send an email to
gmat@manhattanprep.com to request the Post-Exam Assessment.
You mention time management as an issue on Verbal and I'd like to know more about that. What was happening—were you spending too much time earlier on and then running out of time towards the end of the section? Or was something else happening?
First, it's not uncommon for people to be fine on practice tests but to have issues on the real thing because they know the real thing counts now. And one of the really common things to happen is this: Because you know it counts now, you get really invested in checking EVERYthing a million times to MAKE SURE you're right (but on a practice test, you'd have been more willing to just pick and move on because it wasn't the real thing)...and then, boom, there goes your timing. And since the GMAT is a "where you end is what you get" test, if your score drops by the end of the section...well, where you end is what you get.
I have a couple of hypotheses about what could have happened on the third test.
Hypothesis #1: When we're trying to correct an issue, we sometimes go too far in the other direction—we overcorrect, basically. And so, while you were in the test center for the third exam, your brain may have been subconsciously flashing back to running out of time the first two times (if that's what happened), and that would cause you to push yourself even faster than you did on practice tests (again, because you know it really counts now), and so you can end up going too far in the opposite direction. You start rushing just a little too much and making careless mistakes without realizing it—and that pulls your score down.
Hypothesis #2: I see this even more than hypothesis #1. People
think that they fixed their time problem but what they actually did was speed up a little bit on all of the problems that they know how to do (thereby increasing the chances of making a careless mistake) and still spending too long on some problems (thereby using up not just precious time but, more important, precious mental energy) on the stuff that they don't really know how to do (or on which they're inconsistent).
That second hypothesis leads to an increased incidence of careless mistakes in two ways—
both because you're now rushing the stuff you know how to do
and because you're still spending too much mental energy on the too-hard stuff. Double whammy.
So the first question is just to ask whether you think either of these could be what happened. What do you think from a qualitative perspective?
Quantitatively, hypothesis #2 would show up in your practice test data if you timed yourself on each question on the official practice test (or took one of our practice tests—we time the questions for you).
Hypothesis #1 wouldn't show up in practice test data, but it could show up in the official Enhanced Score Report (and so could hypothesis #2). They aggregate the data into four "quadrants" of the test (ie, they don't give us data question by question), but it's still often possible to tell whether one of these things is going on.
They do charge for the Enhanced Score Report (ESR)—I think it's about USD30. This post talks about what data is included and how to analyze it:
https://www.manhattanprep.com/gmat/blog/enhanced-score-report-part-1/Take a look to see whether you think you might want to get it. There is always a risk that your data aggregates in a way that means we can't tell much, so I can't guarantee that the data will be useful. In general, the timing and performance data is pretty good for both the Q and V sections. The data on content is more useful on the Q side than the V side. But if you're baffled as to what's going wrong, then this is one way to try to get some real data to figure out the answer.
If you do get it, feel free to tell me the information here. Part of the details are written out in a way that you can copy-paste, but that written part doesn't include the correct vs. incorrect data on the timing pie charts (what your average times were for correct vs. incorrect problems by quadrant). I definitely need that detail in order to try to figure out what was happening with timing.
Finally, bigger picture. How much of a factor do you think performance anxiety is playing in this? We're all more nervous on real tests than on practice ones, of course. But some people feel that anxiety more strongly than others and it can really affect your performance on test day. A lot of times, people will report feeling full of adrenaline—and some adrenaline is great. But too much adrenaline is actually an anxiety thing and can negatively impact your performance.
How did you sleep the night before? The week before? How did you feel the day or two before and the day of? What did you do, study-wise, in the 2-3 days before the exam? The morning of?
What differences do you remember, no matter how small, between how the real exam felt and how the practice exams felt?
After your official exams, did you remember as much detail about the exam content and experience as you do after practice exams? If there's a significant difference—if you remember significantly less after the real one—that can indicate mental fatigue or performance anxiety or both (they're highly interrelated).
