i applied R1 as well. i submitted my application about 2 weeks ago. like some of you here, i didn't receive the 12 digit PIN number initially. i called the admissions office yesterday and the first guy told me my application was put on hold because one of my recommenders didn't submit her letter. i found that odd because she even showed me her confirmation notice. i called back and after some more probing, the guy said, "oh...you're right. sorry. we do have the letter. you will be receiving your 12 digit PIN/status email shortly."
so afterwards i wondered, would my application still be considered a R1 app? i submitted it before the deadline, but it wasn't viewed as "complete" until yesterday (even though that wasn't even my fault!).
overall, i haven't been very impressed with anderson's student services. back in june, i tried scheduling an info session but got no response for several weeks. when they finally got back to me, it was too late (i had already left the LA area). so i get paired up with a student for a phone interview. this student put me on hold for 5 minutes. the reason? because his girlfriend called! wth. i just didn't think it was very professional.
but there's probably no point to this spiel....as i would gladly accept to attend anderson if they offered me admission. haha!
