5 Common Mistakes in CU Boulder Essays
Being generic: mentioning 'prestigious faculty' or 'world-class research' without naming specific people or programs.
Writing about the campus location instead of the academic experience — city essays should connect the location to your goals.
Listing accomplishments instead of showing fit. The essay is about why you + this school, not a second resume.
Repeating information from your Common App essay. Supplementals should reveal new dimensions of who you are.
Forgetting to proofread for the wrong school name. CU Boulder admissions officers see 'Why [other school]' essays every year.
