Hi tyrion,
You've provided a lot of information, which is good - I'll need some additional information to properly diagnose what's been going wrong for you on Test Day though.
1) How much time did you spend studying before each of your GMATs?
2) What GMAT resources (books, Courses, etc.) did you use?
3) Did you take any of these Veritas CATs more than once (if not, then which CATs did you use when you studied before?)? How did you score on the GMAC CATs?
4) What time of day did you take these CATs and what time of day were your Official GMATs?
5) On Test Day, did you ever have pacing problems in the Quant or Verbal sections? Did you finish early or have to rush just to finish? Did you have to guess on a bunch of questions at the very end (or did you ever leave any questions unanswered?)?
6) How long was the ride from your home to the Testing Center?
Here are the immediate issues:
1) Taking 6 CATs in the 2 weeks leading up to Test Day was NOT a good idea. You likely "burned out" a bit (and didn't even realize it during the Exam). You should take no more than 1 CAT/week.
2) The lack of sleep can ABSOLUTELY impact your performance on Test Day, especially later in the exam (during the Verbal section) when fatigue really starts to set in.
3) Your Official Scores are consistent. Assuming your Scaled Scores on your first GMAT were close to the scores on your second GMAT, there's some kind of "disconnect" that occurs on Test Day. As such, you have to make your next set of practice CATs "match up" with Test Day in as many ways as possible.
In answer to your question:
-Business Schools don't care how many times you take the GMAT; if you score higher on your third attempt, then THAT'S the score that they'll pay attention to.
Thankfully, all of these issues can be fixed. The GMAT is a predictable, standardized Test, so you CAN train to CRUSH it.
GMAT assassins aren't born, they're made,
