I am also heading to Tepper (ACO program).
I accepted the offer a week ago, but no one from the school has contacted me yet. should they?
If any one is an international student here, did OIE inform you about the status of your I-20?
What's the ACO program? A current student calls the new admits a few days after the decision date.You should receive a form in mail which details about the process to get an I20.
ACO and OR are pretty much the same, ACO stands for Algorithms, Combinatorics, Optimization.
I received the email but nobody called me... .
