I took my GMAT yesterday, and received a score of 650 (48Q, 31V).
I had already postponed my test once, and had the gut feeling (which was in retrospect substantiated by my practice test scores) that I should postpone it yet again. But I didn't, hoping against all odds, that I would do better on test day.
I didn't. So here goes my documented attempt to start over.
The GMATClub forums helped me improve my Quant score tremendously - I scoured the forums regularly and adopted shortcuts and timing strategies that helped me overcome most of my weaknesses.
In June, when I took the first GMAT Prep test (scored a 640, but didn't record the raw score breakdown) I was only able to answer 31 Quant questions, and got 14 wrong. So you can imagine what the score breakdown must have been

In verbal, I had 3 SCs wrong, 3 CRs wrong (perfect on RCs).
Somewhere between then and now, my Verbal got progressively worse, with two exceptions - one
MGMAT and GMATPrep test that gave me a 45V and 40V respectively. I think during the
MGMAT, I was in rare form and had laser sharp focus. Anyway, I used the
MGMAT SC guide, Powerscore CR... Did OG 12, quant and verbal books.
Now, I'm going to take a break for two days, since retaking the GMAT pushes my plans to apply for R1 - so I need to come to terms with that first.
But I definitely think I will be able to improve my V score while keeping Q [I was not born in the US, but my first language is English and I did all my schooling from KG to Masters in English. I attended a strict prep school, but managed to daydream through the grammar lessons]
How I will make this improvement is still the big question...
I think documenting things here will keep me accountable.
Anyway, off to enjoying my weekend after 3 months of ignoring friends, family, health... Basically getting my life back for two days =)
PS This post is not very well thought out - randomly dispersed information is quite representative of my state of mind - disappointed, yet mentally preparing to beat it this time around!
