I just took the GMATprep practice test again (Q:48, V:42, 740). I find the grading system rather strange. On the quant, I missed 10 questions (starting with the 4th question), yet I still scored a 48, even though my performance was clearly poor. By contrast, I missed only 4 verbal questions (starting with the 9th question, and the rest were spaced out pretty far), but my verbal score plummeted all the way to a 42.
I understand scores are not calculated by how many right Vs. how many wrong, and that the first 10 questions give a lot of weight to the overall score; this makes me wonder even more, since my first ten on the verbal were WAY better than those on the math.
Perhaps I was just incredibly lucky that all the math questions I missed happened to be part of the 25% of non-scored questions on a test? Heck, I'd imagine I would have a greater chance of getting hit by a meteor than that happening...
Could there be some bug in the GMATprep software that produced such strange results? I hope its just a bug... or else I would have zero margin of error on the verbal section...
although there are lots of rumors/speculations about the first 10 questions vs rest, etc, in this case its pretty simple percentile difference. The verbal and quant raw scores are cannot be compared to each other - remember, this is a standardized test. A 42 in verbal is in the 95%tile, a 48 in quant is only in the 85%tile.http://www.gmatcat.com/Percentiles.html
btw as a point of reference, I took the GMATPrep tests
3 times and I missed from 6 to 10 in quant (score ranged from 48 to 50) and from 5 to 8 in verbal (score ranged from 41-44)
