Columbia summer program for theatre- help!!

Okay, so I’m a junior in high school, and originally I was signed up for the Oxbridge New York College Experience this summer at Barnard. Unfortunately, the program I wanted (musical theatre) was cancelled due to low interest. I could still go with musical theatre as my minor and another program as my major, but I really want my central program to be theatre-related. I’m now looking at Columbia’s summer program, with Theatre Collaboration as my potential course. Does anyone know how the program is (not only the theatre course, but also the day-to-day experience)? Also, I’m kind of a more reserved person- is it hard to make friends? I need to decide ASAP if I’m going to apply, so any information would be helpful!
