My D completed the round of 13 yesterday. She got 11 of the 13 she preferenced, and then two from her bottom 5. Said that her schedule had her criss-crossing the campus between Urbana and Champaign all day. She then preferenced her top 7 for next Saturday. Sounded like a fun and very long day.
One small surprise is that one of the two she preferenced for the round of 13, but didn't get, was a house she had a recommendation for.
