I am absolutly inlove with this school. My experience here was outstanding with a diverse student body, a competitive learning environment, and excellent afterschool programs I feel prepared and ready for college. They have an amazing music program, at our last concert we played Carmina Burana, one of my best High School memories. Also, the schools unique architexture makes it one of a kind. I found the open classrooms to be the best experience I've ever had, I saw more people during the day becuase the hallways are so open, and I did not have any issues focusing with the background noise, and I dont know of anyone who has except a kid with servere ADD.
