How to write college supplements without repeating yourself

IIn Stanford's admissions office, a single application could run to nine separate pieces of writing, while other colleges asked for a few or just one, and counts change every year, so check each college's current prompts. Supplement season brings a particular dread. Your main essay is already about what you want to study, and now one college asks for several more pieces. If everything returns to your field, you worry about sounding repetitive and staged. If everything wanders, the reader loses the thread of who you are, and a scattered file is hard for anyone to champion in committee. There is a way through both problems, and it starts by planning the whole set at once.
