I got a 740 on the GMAT test I took yesterday. I panicked during the quantative section when I got to the 8th or 9th question. It wasn't that difficult of a question, but I am convinced that the correct answer was not one of the answer choices. Maybe it was an experimental question, but I worked it out after the test and came up with the same answer. It ticks me off because I spent about 6 minutes on that one question trying to work it out during the test and totally threw off my timing for the rest of the questions. I ended up having to guess at a couple difficult questions later in the section that I probably could have figured out if I had a few extra minutes.
Luckily, however, I did very well on the verbal section and was able to pull up my overall score. I found the 1000 SC document from this website to be very helpful, as I was able to quickly breeze through the SC questions on the actual test.
I'm thinking about contacting the GMAT people to inform them of their faulty question. Does anyone know how to go about doing this?
