Whoa, what a nightmare. When you are in the 'moment' and have basically trained yourself for months to write an intensive exam like that, having computer components fail can totally throw you off. I received a pen that didn't work properly despite testing it prior. That in itself caused blood to rush to my head and I froze for a few seconds during the essay portion of the test.

If I were you, I would send Pearson VUE a letter to discuss what happened. I'm not sure what kind of alternative recourse they would provide, but something like that is definitely noteworthy.

One of my Kaplan instructors said that a former student of his had to write an examination on a day when an adjacent office had a live band rehearsing their songs. This person also wrote to or called Pearson VUE to file a complaint.

They will take your concern seriously. I'm sure of it.

O yeah! @#$% happens! Don't get upset though!

I also had problems with the computer when taking the test for the 1st time. Making long story short, I had to rewrite the second essay coz of some troubles with the PC. So I had to spend some 40 min extra on the AWA section. The final score was...guess what?? 600 just as yours!

I called the pearson vue and everywhere I could. Each of the places I called said it was not their specific responsibility. But I was very insolent and kept on gettin on their nerves They finally opened a "case" for me.
So one beautiful day (probably in couple of weeks after the test day) I received a letter stating that I could retake the exam for free.

So hey! Be a bit (or alot) insolent and keep calling them! Coz e.mails are not good in this case.

Good luck!

PS I'm sure you will be able to raise your score considerably, coz you have already got 600 while panicking and spending your attetnions to the problems you had with PC, rather than to the problems you got on the screen
