I'm not really new to the forum; I actually read posts here pretty often. Nevertheless, this is my first real post.
I took my official GMAT today, and after months of preparation -- I started studying this past April by taking the
MGMAT -- I only managed to score a 560.

Talk about heartbreak!
After my
MGMAT course ended in June, I studied almost religiously. I took a test per week every week up to this past Sunday, July 25, scoring progressively better with each test. My scores were as follows, in order: 590 (Q36, V34); 620(Q36, V35); 660 (Q39,V41) 630 (Q41, V35); 660 (Q43,V38). The final test was taken 3 days before the real exam. I scored a 660.
Today, on the official test I scored a 560 (Q31, V36). I don't know or understand what happened to me today. I completely choked. I was so lost throughout most of the Quants section. Then, finally, when I got to the last question, I selected my answer, clicked next and before I could confirm the answer time ran out. I know this cost my A LOT of points. After part 1, I was so upset at how the section had gone, I couldn't even complete the verbal in good faith. I completely lost it.
I guess my question is: Now what? Where do I go from here? I feel like I need to get a better handle on the Quants concepts, but I don't know where to start. I've noticed that I struggle a great deal with DS questions. With verbal, RC, of all the subject matters tested, is by far my best. Occasionally I'll miss one RC question, two maybe, but usually I get them all right. CR is the wort for me. I am never confident in my answer choices there. SC, went through
MGMAT's SC guide, but I guess now I feel like I should go through it again.
I spent majority of my preparation time focusing on my quants skills, and still, I feel like I am lost with the concepts. Even in my practice tests, of the the quants questions I got right, I feel like I got them right because the questions mimicked in some way, though not exactly, a question I had previously seen, and I'd just memorized the procedure.
I guess I'm wondering if anyone else experienced the results I did, and how they got through it. Right now, 4 hours post taking the official test, I feel like letting go of my B-school dream. But, hopefully, that's just how I feel today and won't feel that way tomorrow.
Any advice would be greatly appreciated. Thanks in advance,
Bovice
