why are you people giving him advice about something you don't know about?
i'm taking the test abroad, too, in paris. my test is also on tuesday. it's not a mistake. i even emailed the lsac people (like you) to double-check. it says right on the second page of the ticket, if you read the fine print, that foreign tests can be on different days and to do what it says on your ticket.
it's true that this could potentially enable cheating, but let's hope no one does that. good luck!
