<p>Yes, you see and send your scores from your account (as well as register).</p>
<p>I don’t see any problem with creating a new account- your psat from sophomore year doesn’t mean anything (unless you graduate a year early).<br>

No idea if they ever see your sn, but that’s why I just used my name.</p>
