I decided to take the GMAT about six weeks ago on a lark. I'm 50 years old and feel as though my career is a bit stuck, so I decided an MBA might be helpful (I work in marketing/product management). I signed up for the test without understanding the implications (thinking I could take the first time just to see what it was like), and decided to press on once I realized that there were financial consequences to postponing or canceling.
Took the
GMAT Prep software test #1, and got a
680 -- very encouraging given that a lot of my math is rusty. Bought the
official study guide and the
official quant study guide, and did practice quant questions one at a time, figuring out for each problem how I might get it right the next time. I also spent some time on the quant problems on this site, but frankly didn't think they matched the flavor of the official guide questions...
Took the
second GMAT Prep and got a
710. Also very encouraging. However, it had become clear that I was taking a wrong approach to the data sufficiency questions. For the two nights before the test, I just sat back and
absorbed the khan academy YouTube video series showing data sufficiency work (I guess I haven't been here long enough to post URLs). It was very helpful to watch somebody who "gets" all of the math tackle a couple of hundred data sufficiency questions.
That said (and, yes, I feel like an ass for complaining given my score), if I had to do it over again, I'd have given myself more time to
become fluid with the math. It seemed like I was knocking it out of the park early, which meant that the questions kept getting harder. Because of this, my lack or "quickness" with the math (because of my lack of practice) caused me to run out of time and rush through the last 10 questions.
This is where I can offer advice: Having been a journalism major and a writer my whole life, I found the verbal stuff pretty second nature (although I spent a good bit of time studying the recommended structure of the writing responses). I didn't "need" to kill the math part. But imagine if I had! My suggestion, particularly to those who'll need to do well on the math to score well, is to
rehearse fluidity. Learn how to break down data sufficiency problems to 2 minutes or so.
