Zoey 101 (2005)

Pacific Coast Academy, an all boys boarding school is accepting female students for the first time since the school was established. Zoey's little brother Dustin is currently a student there. Zoey decides to be one of the first girls to become a student at PCA. This is very exciting, but also very scary. Fitting in at a new school is hard enough, but going away to boarding school and living on your own when you're only thirteen can get a little crazy, especially when the girls are heavily outnumbered by the boys...
