I'm kind of in the same boat. Both of mine were sent in last week via regular US mail. Did anyone else send them in by regular mail? If so, how long did it take to get there??
Oh and CalGirl... did you go to berkeley??
How do you know if they have been received? Do they email you?
Yup, I go to Berkeley (and its nice to see so many Bears on this board!). Hopefully law schools like our school
Anyway, you can tell when you're letter has been received by looking under LSAC's "Account Status" and then "Letters/Reports." It should say your professor's name and the date the letter was received.
FYI, I called LSAC yesterday and the operator said they were really backed up in terms of confirmation emails; my LOR showed up online before I got an email (an even at that, it said it was processed 10/18 and I only was able to see it on 10/22).
