Your chance me post had stellar advice from a lot of people who’ve been on College Confidential for a while. Almost all of them made note of the presence of your school’s college counseling office and encouraged you to connect with them to get guidance from them.
The question you’re asking here would be a great one for your counselor; they will be far more equipped to help you figure out the right slate of schools to apply to, including any ED options (whether Columbia, Duke, or somewhere else, or nowhere ED), and can factor in your specific ECs more fully.
