I agree pelihu.....my score is one of the examples of weird set....(Can we say that there is margin of error for GMAT? This set may be example of same.
I was reading in barrons guide book that in Toefl, margin of error occurs and that ,even if taken same day, two same performance may be judged differently. Though I am happy to have 700.
However, all the verbal scores are not in 45+ range....from 35 to 45.....difference is very little to large case by case...
