I have had a very similar experience as Delany2000's. I went down from a 690 (Q 47 V 38) with a very nice split (I am not a native speaker, so I was happy with my verbal score too) to a 610 (Q 41 V34). Talking about being demoralized. First, I wanted to kick me in the butt to re-take the test in first place, then I wanted to strangle myself for taking the test in the morning. I am not a morning person and I had only a couple hours of sleep the night before (stress, I guess).
I wanted to take the test again because I had not a whole lot of preparation the first time around and I thought if I prepared little more, may be I can score somewhere between 720/730. I was not greedy, I just wanted to improve my candidacy little bit, I am 31 and did not go to IVY school and do not work for a fortune 100/50/10 whatever company. Well, now I created a mess. Now, Adcomms would probably not know what I am capable of anymore.
Now, besides my issues there are definitely some ETS issues. I believe ETS just released a new version of the GMAT SW and traditional way of preparing for the test might no longer apply to everyone. I do believe that Q no longer starts with an average question, and a prob/combination question within first five questions does not translate well to my score either. I also had one more prob/comb. question later in the test. I know because of my lack of sleep and therefore, concentration I might have made some silly mistakes. But, ETS scores should not vary by this much. I know that I am lot lot better than a 41 in the Q. But, it hardly matters anymore, my self esteem and confidence have gone down the toilet yesterday.
Be careful if you are re-taking the GMAT to bump up your score little bit. Don't be ****headed like me. I am rethinking my whole ambition for business school now. I know Adcomms only consider the highest score, but this has been really frustrating.
I do not mean to vent but I just wanted to advise everyone to think first and think more and then act.
Good luck to everyone!
