Hi s77,
As BB mentioned, you’ll like get a variety of answers to your question. In the case of sending all your scores, sure, it makes sense that doing so would show “perseverance,” assuming that you were to continue to increase your GMAT score until hitting your score goal. However, on the other side of the coin, if you’d rather not show the folks in admissions that you scored 650, for example (50+ points below your goal score), then there is no reason to send in all of your scores. Because at the end of the day, let’s be honest, some folks score 720 and admit only one score. So I can’t imagine a situation in which those applicants are penalized for having only one score, right?
