I have an LSAT playlist on Spotify that kinda tracks each stage of LSAT with specific songs. Waiting for scores is "Waiting Around to Die" by Townes Van Zandt, lol. It's a long month.
It's odd... it could just be because they genuinely don't think you would have attended? Admissions are a mysterious thing. You have better acceptances, so I'd just concentrate on those. :)
