The long and the short of it
I have a mediocre undergrad GPA (3.0), so I knew that a decent GMAT score was going to be necessary, if I wanted to get into one of the incredible schools that I have been targeting. So, I studied a bunch for two months and wound up with a 740 Q49 V42 this morning. That's good enough for me, I think.
My background
I have an undergrad in engineering, a master's in biotechnology, and six years of very technical experience in tech and biotech. Anyone reading my resume would call me a quant, but the reality is that I'm just a very pragmatic poet. I spend most of my free time reading and writing. Honestly, I read 50-100,000 words of fiction and non-fiction/week outside of work. And at work I spend a lot of time reading primary biological research (because it's my job, not because I have a strange way of slacking off).
My study plan
So, my plan was to study almost every day for about 2 months. I came reasonably close to this. I probably only studied 6 days/week, but I definitely managed to put in more than 100 hours, maybe closer to 150 or 200 hours. I'm not sure; I'll do the math later.
I didn't really spend a lot of time on this forum until a few weeks into my studying so, I was a bit clueless about how to spend my time and what to spend my time on. I eventually got up to speed, and managed to get in several hours of fairly productive studying per day.
In terms of balance, I knew that I was a poet (in quant's clothes, if you prefer, but still a poet), so I spent the vast majority of my time on quant. By my estimation I spent at least twice as much time on quant as I did on verbal. Oh, and I spent next to no time on AWA, so we'll see how those scores come out.
My materials
OG-This is mandatory
OG Supplements-Totally worthwhile
MGMAT-Oh. My. God. These should be included in the price of the exam. Honestly. If you sit for this exam and you don't work through these books, then I don't know what you're thinking. Of course, if you're like I was for the first several weeks of my prep, and you don't know what they are, then you can be excused. But if you're reading this, you know. This is the most valuable use of your time. If you don't have time for these, then I doubt that you have time for b-school.
Kaplan-The normal book is a decent intro. Do it in a few days, though. Don't waste forever on it.
Kaplan 800-It's not really as advanced as they want it to sound, but it's worth your time, but not at the expense of time spent on
MGMAT books.
Petersen's-Crap
McGraw-Hill-Worse than crap
I also watched a few of Grockit's webcasts. I highly recommend them. I don't know that I actually learned anything from them that I didn't learn elsewhere, but they're well done, and they kept me engaged.
My practice scores
GMAT Prep #1 750 Q49 V42
Kaplan 720 Q42 V47
GMAT Prep #2 710 Q42 V44
GMAT Prep #3 (Reused) 740 Q49 V41
My test day experience
The whole experience was almost exactly how I pictured things. Really I was not surprised about anything. The mix of questions, their difficulty level, the test center: it all matched my expectations. And my expectations were based largely on the information in this forum. So, if you read all of the major posts on this site, I can't really tell you anything new.
Summary judgment
As you can see from my scores, I definitely plateaued after a while. I felt it. There's no doubt about it. Once I got pretty good at these problems, I really struggled to keep myself engaged, and while I kept putting in the hours, my heart wasn't in it. That's on me. I'm not proud of it, but I'm just a working stiff like anyone else. I have a wife, a demanding job, and some very delicate but grand dreams. My personality will only allow me to distort the importance of this test in my career so much. At my day job, I'm tying to cure cancer (or at least the build the tools to allow others to do so). That's what is important to me, and GMAT can only monopolize my attentions so much. GMAT prep has been an adventure, but I can't say that I'm sad to see this time pass.
I'm happy with my score. It's above average basically everywhere, and that's what I needed to keep this dream alive. I think that it accurately reflects the performance I gave on test day. Would I have been happier if I scored higher? Sure. Who wouldn't? But in the end, I think that Farmer Hoggett has it right. That'll do, Pig.
