45 days for me too (took 10/1). Sent them an email this morning (says it will take 3-5 business days for a reply). Also tried calling CA BOP but no answer. Will try again later today. :/
Edit: Called them again. The receptionist said that anyone who took it after 9/15 is part of the batch that has not been mailed yet. To the best of his knowledge, he -thinks- they should be sending them out some time this week since it has been 45 days now (for me, anyway; been nearly 60 for others). But, he isn't positive about it getting mailed this week since he isn't the one who handles that sort of thing, so don't take his word for it. He only knows what they tell him how long it usually takes. For all he knows, might not be till later this month.
Also, got an email reply from BOP. Basically says they won't talk to me about the exam status unless it has been 60 days since my exam date. (So if it's been 60 days for anyone else, maybe you guys can try.)
So, optimistically, perhaps they are mailing results this week...? Did anyone else who called find out anything different?
