I finally crossed the 600 barrier on monday, however while applying at reputable schools will this be viewed as a positive indicator e.g someone who is persistent and really wants to achieve or otherwise. I'm remaining positive and would like to see it this way but I do need your feedback. I have 5 years of Information systems / development/analyst experience with a bachelor from Unversity of texas - 3.0 gpa.
Quick answer is no, that won't hurt especially you did so much better on 3rd try.
At the same time, I wonder if taking multiple times really hurts. Do admission people really look at everyone's scoring trends from the Official reports? I'm not sure if they have the time. When they say they only consider the highest score, I'm believe that's the score they consider (on the application there's only 1 space to put in that number). Later on, they'll probably have some admin to verify that the score you put into the app does indeed exist in your official report.
