Supplemental essays are where many admissions decisions are made — particularly at highly selective schools where nearly all applicants have strong academic records. Here is a type-by-type breakdown of how to approach each.
The 'Why This School?' Essay (Most Important)
This prompt — in various forms — appears at most selective schools. It requires specific, researched answers that could not apply to any other school. Reference particular programs, professors, courses, research opportunities, traditions, or pedagogical approaches that you have genuinely researched. Generic responses that mention 'diverse student body,' 'strong academics,' or 'beautiful campus' immediately signal that the student did not do meaningful research. Rule: if you could remove the school's name and insert another school's name without changing anything, rewrite entirely.
The 'Why This Major?' Essay
Trace the intellectual origin story of your interest — a specific experience, book, conversation, or discovery that sparked genuine curiosity. Connect your specific background and interests to this school's particular resources (a professor's research, a specific course sequence, a lab, an interdisciplinary program). Avoid choosing the most popular majors (CS, pre-med) without genuinely compelling personal narratives.
Short-Answer Prompts (50–150 words)
MIT's 100-word activity description, UChicago's short-answer questions — these reward precision and intellectual character. Do not summarize; reveal. A 100-word response about your love of origami should make the reader feel what origami means to you intellectually, not just what you make.
Quirky Intellectual Prompts
UChicago is famous for 'uncommon essay' prompts; MIT asks questions like 'How did you find your way to us?' These prompts test genuine intellectual personality — your capacity for playful, deep thinking. The worst response is trying to be clever strategically. The best response is finding the question genuinely interesting and engaging with it honestly.
