So after four months and countless hours of prep I took the GMAT yesterday and was disappointed with a 640 (36 Q, 41V). I was shooting for the magical 700 number and fell short, very disappointed. Quant just killed my score, if I would have gotten even a 40 on quant I think I would have gotten 680, a 45 probably a 700. The problem I am having is that on prep tests I was scoring on average around 680 and scored 700 on my last GMAT Prep test about a week ago. Since then I have studied mostly quant and have been scoring around 45 on quant on practice tests and then put in a four day quant study, probably 12 hours of studying just quant. I went to the exam confident and was not nervous, AWA went fine no problems. Took a short break and started quant, I thought I was doing awesome. I knew almost every question and had time to double check most answers, I was not rushed or nervous at all. Probably didn't know maybe three or four questions. I thought it was easy, easiest quant section I've done so I'm thinking it was not registering my correct answers. Coming out of quant I thought I nailed it. Verbal was fine I thought I did well. I see my score and cannot believe the 36 43% on quant, there is no way. I haven't scored that low on the quant portion since June or July and scored around that before studying the four months and countless hours. I now am convinced either a) the GMAT is the trickest test ever or b) the quant score is wrong (I hate to say this because I don't like making excuses and I respect GMAC but I am confident I nailed it), and I don't think the GMAT is that tricky. I have not been disappointed on a test since probably freshman year of college, as I have gotten A's on everything since then and I passed all three levels of the CFA on the first try so my knowledge and study plan have worked awesome up to here. I'm relatively smart I would say but in addition I study alot so I put in the hours. I know people probably think I may be a sour loser and/or that I am crazy and maybe it is possible that I got a 36 on quant but I really thought I nailed it and had time to review most problems so I cannot understand the score on quant. Does anyone have similar stories like this? Anyone know of a time when a GMAT score was incorrect? Any way to have GMAT double check the scoring or see my exam? Anyone know how many questions you need to get wrong to get a 36 or what range of questions you are at, i.e. I imagine a 36 means you cannot get any 600-700 questions and are getting 3/4 of the 500-600 questions right, I mean just how bad is a 36? I know I do not have many options but wanted to see if anyone on this forum had any knowledge on this. I know I can take it over but the 36 43% on quant really are not going to look good to top schools even if I do retake it. I would greatly appreciate any feedback. Thank you in advance.
