Puzzled over disastrous Quant Score - How to focus for the retake  [#permalink]

Dear all,

yesterday I took the GMAT and had an overall good test-taking experience (not speaking of the result).

I chose the Q - V - IR - AWA order like I used to in my practice exams. The first question of Quant got me on the wrong feet, one of those express "mean of abc" in terms of x, but over the course of the Quant section I built up confidence and thought it went overall well.
Taking this confidence to the Verbal section made that part more enjoyable. However, when I've eventually seen my score on the screen after finishing the AWA I was just shocked and am still puzzled.

I scored a mere 650, with a disastrous Q39 (37th percentile!) and a V40 that actually matches my expectations.
My Prep Scores were as follows:
Initial w/o studying: 560 (Q and V in the mid 20s)
after 1/2 week full-time: 630 (Q45 V25)
after 1 weeks full-time: 700 (Q48, V37)
after 2 weeks full-time: 710 (Q48, V40)
G-Day in Week 3

During that time I reviewed the MGMAT books (except CR and RC since I'm already good at this section) and went through the OG-Books. Furthermore I maintained an Error-Log and carefully reviewed each question I got wrong. However, I am still not ok with some problems, like the aforementioned express "abc" in terms of x.

Now that I received my score and the ESR (shared in the spoiler) I still don't know what really went wrong in Quant. The feeling I had during the test was comparable to my 700er prep scores - good, albeit knowing that I made some mistakes.
Also note, that I got roughly 60% of the question right, or 15 questions wrong, difficulty ranging from Medium to Medium-High. In the prep exams I got 12 and 10 questions wrong.
During the test I had no problems with pacing (4 mins of time left at the end) but it puzzles me that my average time per question was 2:13 -> that would mean I haven't finished in time, but the ESR indicates otherwise (answered 37 of 37).

Does someone have an explanation for this extremely low score?
Should I cancel the score?
How should I focus my prep within the next 2.5 weeks?

Thank y'all!

Hi. Sorry to hear about your score. There are a few possible explanations - the new section order is one for example. Some feel that going into quant cold is not a good idea and I think GMAC has some evidence that people don't score well by going cold into a section instead of using the traditional sequence of AWA, IR, Q, V. My theory is here: https://gmatclub.com/forum/new-gmat-str ... 43120.html

Other reasons are just gaps and holes in your quant skills, and the test seems to be able to find and target those... or so it seems at times.

I would probably cancel to avoid having to explain things later. You can always restore the score if you really need it back.

P.S. You may want to attach your ESR as a picture/screenshot.

Thank you for your reply. The thoughts about the question order are interesting but I had no problems with it during the practice exams. Also did I take the practice exams under exams conditions (in the uni, same time, no extra breaks etc.).

Should I go on with my procedure as I already did? Problems solving, Reviewing, Concept Review in a 75 to 25 Quant to Verbal Split? Or would any other strategy yield better results?
