I believe it is. The thing is I am required to submit thru my undergraduate university, rather than my post-bacc university. And so, it's been a pain reaching them. Every month or so I call, am instructed to send an email, send it, then never hear back.
If it is a committee composite letter, which I now see why they would want more letters. Should I submit differently? I've invested a great amount of time to build relationships with these 4 authors (at the expense of relationships with other potential letter authors). That's what I'm worried about. I'm also leaning away from a committee composite letter because I've never met the advisor who would write it - and I never will. She would receive great letters, but I really have no means of meeting her in person because I'm far enough removed from my undergraduate degree. On the other hand, schools have told me they would prefer one letter over individual letters.
Glimmer, you've helped me before! Can you do it again? 🙂)))
