i called the nbme today and asked if scores would be released tomorrow, and their response was........some scores will be released, but the person i spoke with wouldn't say or didn't know exactly whose scores are going to be released tomorrow, but hopefully they will release some.
as for the june 12th test date, i wouldn't hold my breath. most us takers from may 20th and on haven't received scores yet. i would imagine that they will be released before the june test takers.
