On the first day of Orientation there is a chunk of the afternoon when you have three options you can do.
1. Attend the Student Organization fair.
2. Watch movies.
3. Join in a Book Discussion group led by a professor.
If you want to do #3 you have till 21. August to sign up for a group and hope to be selected. There are some law related books, some Shakespeare, and a few classic books (such as Scarlet Letter).
