I don't have the slightest idea what the schedule is. Duke had this nice page with all of the activities, and I'm really stoked. I'm really stoked about going back to visit P&S too, and no doubt, I'll be there.
I am one of the 1st years working on revisit weekend. Although we are still working out the final details and I don't want to give away everything I will let you know the general scheme. You arrive and check in Thursday morning, participate in some talks about curriculum, lunch, and then some other fun stuff in the afternoon. That night we have a lot of fun stuff planned (so if you can only make it for one day I would suggest staying Thursday night). On Friday there is a lot of informative stuff and opportunities for excursions throughout NYC. Revisit is a lot of fun and I am looking forward to meeting you all and convincing you that P&S is the place to be.
