If you’re registered to take the October LSAT, yesterday was the deadline to change your LSAT test date or LSAT test center. There’s no changing anything now; you’re signed up to take the LSAT on October 6, at whatever LSAT test center you chose when you signed up. This is not a dream. This is for real.
There are nonetheless a few ways you might not end up with an October LSAT score. If you end up deciding you’re not ready, you can withdraw your LSAT registration online up until midnight EDT on the night before LSAT test day. There’s no notation on your score report if you do this.
If you simply fail to show up for the LSAT, you’ll be marked absent, and law schools will see on your score report that you were absent for the October 2012 LSAT. If some last-minute emergency comes up and keeps you from showing up, don’t worry; it’s not a huge deal.
