same for me, this test is annoying. Did it now 3 times got 560, 600, 550.Thats a joke in the practice exams I was always between 650-730.
Actually in the last attempt I felt very confident in the Verbal part and was sure that I will score around 34. But I got a 23. Really devastating.
But I dont give up, and give the next try in february. Actually what really pisses me off is that you dont get to see your mistakes, so you will never know your weakness in Verbal. You just see a damn score
And you will never know if a there is mistake with the software etither, because the guys from GMAC will never give you a fair answer.
