Generally 2 weeks before the start of the board, which was March 4th. I have seen people say 1-2 weeks though, it will depend on your recruiters, USAREC turn around, and any need for waivers.
Yup. It really depends on how adamant your recruiter is on getting you to this board. There's a lot of back and forth between the "proponent" and the recruiter.
A little off topic, but there's this one fresh grad (college) who scored a 78 on the SIFT. And from what I heard his recruiter put off his packet until they can find quality LORs. He's been waiting for at least 4 months now. He could've been on this board with us.
I guess they want to be a shoe in on his first take
