What daily life is like at Phillips Academy Exeter's summer program??

My daughter is going to Exeter’s program this year and she’s curious about what the students do daily. How much free time? Are the chamber groups hard to get into? (orchestra, instrumental groups) Plus, I want to know where she can get the textbooks for cheap. She’s attending the access exeter program for eighth graders, and she’s taking the Global Community classes. I’m not very interested in buying expensive books for her to use for five weeks. If anybody has taken this course, please reply on how expensive the books were, or what type they were. Thanks!
