I "started" studying for the GMAT about a month before my actual date. It mostly consisted of me going through the GMAT800 Kaplan book. Initially, I wasn't too worried. I was an engineer as an undergrad so the Quant section wasn't particuarly difficult. But, when I got to the sentence correction questions, my performance was absolutely miserable. I had assumed that my intuition would allow me to answer most of the questions correctly, but I guess that my grammar skills just weren't up to snuff.
About a week before the test, I started freaking out...I kept contemplating pushing my test date back so I could really study for the sentence correction questions and the data sufficiency math questions. Fortunately my family and friends slapped some sense into me and made me actually sit down and study. I took the 3 days before the exam off from work and prepared for several hours a day.
I started by going through the Princeton Review GMAT book and took a really good look at their strategies. I think that it was the PR book that really saved me. Their data sufficiency and sentence correction strats were simple but they made me much more efficient at doing the questions. By the time I got through the book on my first day of "hardcore" studying, I was feeling much better. The rest of the week, I just did as many of the OG questions as possible. I took a Kaplan CAT the day before my exam and I got a 670...my friends had told me that the kaplan tests tend to underestimate your score, so I figured that 700 would be within my reach.
Anyways, I picked an afternoon slot for my exam...wandered around NYC for a few hours before finally showing up at my test center. I didn't know that you couldn't bring your own pencils into the test room, so I had to leave my "lucky pencil" in the locker. The essays weren't that bad (I guess that I'll find out how I did sometime soon), and finally got to work on the math section. One of the problems I had when taking the practice tests was concentrating for long stretches, but that wasn't a problem when taking the actual thing. Before I knew it, I was on problem 30-something and I had 25 minutes left. So I got to the last problem and just sat there for a long time stretching...answered the last question with 10 minutes to spare and got to work on the verbal.
I hate CATs...the entire verbal section, I kept wondering what my score would be. When you know that your score will pop up at the end of the test, it makes it that much more nerve-wracking!!! It felt like an eternity, but I managed to finish. I answered a bunch of questions about who I wanted the scores sent to...and then the question popped up on the screen. Do you want to cancel your score or keep it???? Luckily I kept it...
Q51, V42 - 770
The other testers are lucky that I didn't start dancing or something. I managed to stay composed until I got outside the testing center and then I called my parents to let them know. I figured that they would be excited for me...Instead what I got was...
me - "Hey, I got a 770"
mom - "What is the test out of"
me - "800"
mom - "is that good?"
me - "yeah, good...its 99th percentile"
mom - "oh, how many did you miss? are you going to take it again?"
me - ">_<"
remind me never to tell my parents exciting news first
