How early should I obtain Rec Letters?

[Sciencewoman]

For anyone to complete their sorority's recommendation form (which is really what is meant by a letter of rec), they need to have detailed information about you. A resume and transcript help provide that information, particularly for the women who don't know you personally.

I saw your post on another thread telling another PNM that you've been on Greekchat and have been preparing for recruitment for a long time. This is pretty basic information about rec letters/forms, which is heavily discussed in many recruitment threads. You may not want to offer yourself as a source of recruitment knowledge -- I'm not saying that to be snarky, but just that it appears you still have some homework to do in preparation for recruitment.
