Don't give up just yet... A 610 is still a very good score! But, if you really want that 700, I say study some more and give it another shot! You already know what to expect, so your nerves should be much better next time...
First, I would like to say that this is a great website! Great job BB. The advises and experiences given here are real. I just couldn't follow through during the test, and thus, I was defeated and very discouraged. Now let me share my experience that was similar to a few others.
Essays- Issue and Argument were from the official GMAT website. Download in pdf file as most of you know already. Straight forward! Recommend going through the topics. It will save you some grief!
Math- My failure began here: There first couple questions were cake and I was thinking they are traps! I double and triple checked them and wasted time. The 4th problem was a combination! I suck at these, but gave it a shot and failed. The middle ones were similar to OG. No S.D. for me. However, there were some tricky wording on longer word problems that I spent way too much time on. But then woops, I forgot to check the time until on number 27 and only 10 minutes left at that point. I started to panic and got real nervous. Wild guesses on at least half of them.
5-minute break- I was pissed and felt really really bad. I knew I was totally screwed. 200 bucks down the toilet like playing the blackjack at the casinos. No free drinks during GMAT.
Verbal- Still very pissed at myself for the math. I couldn't concentrate. The 3rd problem was RC-75 lines. I didn't know what the hell I was reading. I just couldn't block the negative thought of my math failure. The whole time during Verbal I was thinking about Math. Blood pressure and body temperature were way too high!
Questions were similar to OG, but SC was tricky. Then again, I was doing poorly so probably got easier questions.
That was my sad experience. A bit of background- My B.S. was in chemical engineering, and I have been a process engineer for the past 5 years. Why an MBA? I would like to learn how to start business ventures. Now feeling bad and discouraged, I am not sure if I should still pursue the path. My goal was 700, and I was way way off. It seemed that the past one and half months of hard work was wasted. Shame on me. I just wanted to share my experience, and maybe it can serve as a warning for others. Don't dwell on the negatives! My math came out much much better than I expected it. Go kill the "beast"!
