Yea, and schools usually look at your top score anyway, so not a lot of risk I think. The profile and score sending are two separte things.
While this is true, the schools that you send score reports to will see ALL past GMAT scores. So if you take the test first time and bomb it, they'll see it. Be as prepared as you can be for the first test and hope you nail it on the spot. $200 isn't exacly pocket change either.
