Prompt
Why Northwestern? What aspects of the Northwestern curriculum or community make it a good fit for you? (250 words)
Ask anything about your applications.
Get answers based on your actual list and profile: which schools to prioritize, how to angle an essay, what to research before you apply.
Which of my Reach schools should I prioritize for Early Action?
Based on your list, Harvard and MIT both offer Restrictive Early Action: you can only apply EA to one of them. Harvard's RAEA acceptance rate was ~7.4% vs MIT's 4.7%. If research is central to your application, MIT may align better. Harvard gives more weight to leadership and community impact. One thing to note: MIT's RAEA is Non-Restrictive for public schools, so you could still apply EA to any public university alongside it.
Help me brainstorm a stronger 'Why Northwestern' angle for Medill.
Strong start with your current draft. A few angles to sharpen it: • Name the Journalism Residency city or outlet you'd target; readers respond to specificity. • If you're pairing journalism with another field, mention the dual-degree option explicitly. • Reference a faculty member's published work you've actually read. Your opening, 'Northwestern's Medill School,' is a solid anchor. The next move is making it personal: what story have you already reported that proves you belong in that newsroom?
