Ah, that guy is applying for MIT. (the system's interface is a giveaway).
Well, as someone who took pGRE multiple times. I worried about this for a while, but got around the hassle somehow.
We have to order official score report to be sent by ETS which will be used to verify whatever numbers we claim.
The copy that we upload is considered unofficial, until verified with ETS's. Hence it is not a valid report on its own anyway.
With ScoreSelect being a legally available option, redacting any of your scores from the copy you upload is not an offense. It just looks weird if done badly. It would be an offense only if your school explicitly states that you must report all your attempted GRE scores. Most schools don't.
If there's anything that I suspect ETS might be lying to us about ScoreSelect, it is when I saw this.https://www.physics.harvard.edu/academics/grad/faq#q38
I have taken the Physics GRE multiple times. Which score will be reviewed, the most recent one or the best one?
You can fill in whichever set of scores you'd prefer on the online application -- the Educational Testing Service will send the admissions committee the scores from all your tests as well.
Reading that literally, Harvard might have access to all your scores, possibly via the same score report format we have, regardless of whatever ScoreSelect option we selected. If that is the case, no point in hiding anything. But it indeed sucks to be treated that way by ETS.
