CU Boulder / Essays
CU Boulder supplemental essays
All 1 required prompt for 2025-2026, each with its own deep guide: what it is really asking, annotated examples, and what to avoid.
Spend roughly the first half to two-thirds of your 250 words on the 'why this major' story, then pivot hard to CU Boulder specifics. The biggest mistake is splitting the essay 50/50 and ending up shallow on both halves. Lead with a concrete moment that hooked you on the subject, a broken carburetor, a data set that surprised you, a debate you couldn't drop, then connect that to a named CU Boulder resource that lets you keep going. The pivot sentence is the hinge of the whole piece.
If you are undecided, do not apologize for it. The prompt explicitly gives you permission. Instead, name two or three threads (an activity, a job, a class) that keep showing up in your life, find the common question underneath them, and point to a CU Boulder pathway for exploring it, like the Arts and Sciences open-option route or a specific gen-ed or program. 'Undecided with a clear method' beats 'certain but generic' every time.
Mistakes that sink CU Boulder essays
CU Boulder requires this answer to be different writing from your Common App essay. Don't recycle a paragraph. Readers see both, and an echo wastes your scarce 250 words.
Skip Boulder's scenery, the Flatirons, ski weekends, and 'great school spirit.' Anyone can write that. Replace it with one academic detail only CU Boulder offers.
Drop in an actual program, course, lab, or center tied to your major and explain how you'd use it. Vague 'amazing opportunities' signals you didn't research. One specific beats five generics.
A forced 'I've known since age six' reads hollow. If you're exploring, say so and show your method. The prompt rewards honest direction over manufactured passion.
