What is a good collage for photography?

i know i'm not even 14 yet but I've always wanted to go to Julliard for collage i'm even starting to learn how to play guitar and ill practice till my fingers hurt.. but i'm very good at photography. i live in upstate new York so it probably will be far away heck i don't even know where Julliard is and i know it will be a tough time for me. I've wanted to be in it my whole life to become a good actress, and no one believes i can. I've always thought to my self i know i can prove them wrong even if i'm in a 30 second commercial i know i can do it but if i get proved wrong i at least want to be in photography with my best friend we are good at that i take really good nature pictures i need something to fall back on my mom is pushing me to be a RN but that isn't me i'm into creativity and i cant be creative when i'm doing open heart surgery or whatever RN's do. please help??
