Well, I made the mistake to indicate my top 5 to receive my score when I took the GMAT. And now that I am not very happy with the score and thinking of retaking, the strategy has changed. Don't send to my top 5 again until I see the score from the re-take. Of course, that means more money spent on additional score reports, but what can you do, the risk is pretty big.....
Anyway, the bottom line is the schools won't get your additional scores unless you officially send scores to them again. If you do that though, all scores in the last 5 years will be revealed.
