I fall into the category of those who are company sponsored to go to a college with a high 400 mean score. Interesting to note however, on the schools website they say:
"In fall 2004, students who gained admission to evening programs and the One-Year MBA program submitted GPA's averaging about 3.0, and GMAT scores averaging 500"
But in the latest US News graduate school publication, the school is listed as having a mean in the mid 400's. Maybe they have old data, or maybe the school rounds up to look good
But anyway...I studied casually on weekends only, and only took 1 GMATprep test in its entirety and I got the mean score (or slightly less) of 500. I admit though, If I knew about this site 6 months ago I would have picked up the official guide (never seen it) and studied that along with a real study guide like Kaplan and taken a few more tests. Either way it just would have been for ego, because my company kinda has me by the balls and its either a state school (UB) or Canisius College where I went for undergrad to be able to remain an employee and have the reimbursement.
I felt like I was doing more like 530-550 during the test though, as I thought I was doing better than GMATprep which I got a 530 on.
I found it very interesting that my scores were nearly an even split, I was bracing myself for a math score that was much lower than my verbal. As I said, theres probably a reason Im the only person on this board that read GMAT for dummies...that was a waste of energy.
