Total - 690 (87%) Verbal - 44 (98%) Quant - 39 (46%) IR - 7 (82%) AW - 5.5 (80%) I'm disappointed that I wasn't able to at least get a 40 on the quant side. I have a liberal arts background, so I guess it is not surprising that my score is pretty pedestrian compared with other GMAT takers. I am not ...

Very nice, Brent.
At the risk of coming across as sadistic, does anybody have a purely algebraic solution to this?

Logic vs. Math concepts
I am consistently under-performing on my Quant practice tests. I feel that I have a pretty solid understanding of the underlying math concepts, and when practicing a few problems at a time without time constraints, I am able to do quite well, and feel very confident. However, under real test conditi...

Brent, The answer is now D because: (m+5)/w>(11/10) - cross multiply to get: 10m+50>11w - plug in m=(3/5)w from the ratio in the question stem to get: 10(3w/5)+50>11w = 6w+50>11w = 10>w = w<10 Since w<10, and men and women can only be counted with integers, w can only be 5, given the ratio of 3m/5w....

David, Great article. I think it describes my experience very well. I did end up finishing the verbal section with about 20 minutes to spare. That was partly because I had all but decided I was going to retake the test after my performance on the quant section. I will definitely take a more in-depth...
