Yes you can get scores before they are officially released.  For some reason the scores aren't all released in the same area's.  I have heard of people using VPN's to log in and get their scores.
Additionally because they scores are released slowly all week.  But  schools are on a different schedule.  They might update and let you know earlier.  I'm kind-of hoping that's true here because in CA they won't be officially released until July 9th.  But his schools may get it on July 6th and I might see them in one of their portals earlier.  (We will see..)
