Hi vagivaldne,
In general, Business Schools will log-in to confirm your GMAT Score IF they plan to invite you to attend their respective Programs and to confirm that it matches the Score that you listed on your application. If you don't list a Score (because the Program doesn't actually require that you submit a GMAT Score), then it's possible that they won't look at your Official Report. That having been said, you have granted them the access, so if someone in the Administration is spending time confirming everyone else's Scores, then that person might inadvertently check for your Score too. If you're that concerned about sharing that information, then the only practical option is to pay to Cancel that result. As it stands, that School probably would not care about your Score either way (the Q49 is nice even though the Overall Score is not going to impress anyone), but considering how expensive a Grad Degree is, spending $25 to put yourself at ease seems like a negligible expense.
You're ultimately asking Admissions questions, so you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement (and the more time that you have to act on that advice, the better). There's a Forum full of those Experts here:
