Here are some things that I like that are related to creativity, college admission, or both: 

College Essay Guy - fabulous resource for writing the college essay. The founder, Ethan Sawyer, has a background in screenwriting and acting so his materials are particularly well-suited for crafting creative narratives. 

Career Vision Jamie - Jamie is so imaginative and makes great and unexpected connections around interests and career pathways. 

Dance Magazine - I recommend reading content on this site to anyone regardless of their art form, because making/doing any kind of art is incredibly physical and there is a great range of detailed and nuanced descriptive and expressive language that is valuable for architecture, fine art, design, music, theater, film... all areas in addition to dance. 

Louisiana Channel - Artist interviews. Great to watch to get ideas on what to say about your creative process.
