Hey, congrats!! I'm the one who posted about the recruitment weekend--I got an email from Dr. Song about it.
" The College of Arts and Science will host the recruitment weekend (March 4-6) on Norman campus. The prospective student can have a chance to tour the campus and department, and talk to the professors and other fellow students. Each of the prospects could get $400 of their travel reimbursed. I am contacting you to confirm if you decide to come for a visit during that weekend. "
I bet you could call Dr. Song or Kathryn Paine, the admissions adviser, about it. I won't be able to make it this weekend, but they told me that if I visit another time they'll still reimburse me! Do you think you'll accept the offer? I'm still waiting for a "counter offer" from ASU (I've been waitlisted but they asked me to keep them updated on my other offers), but I think I'll most likely accept OU's offer!
