What's the biggest mistake students make on the Common App essay?

The most common Common App mistake isn't a typo; it's writing about an event instead of about yourself.

The biggest mistake is describing what happened without ever showing what it taught you or how you think. Scenario: A student spent 600 words narrating a soccer championship play-by-play with zero reflection, and a reader learned nothing about her, until she cut the game to two lines and spent the rest on what losing revealed. MIT's admissions team repeatedly stresses reflection on their blogs. EssayCompass explains where reflection belongs in each paragraph, so your essay reveals a mind, not just a highlight reel.

A close runner-up is trying to impress instead of connect, listing achievements the activities section already covers. Scenario: A high-stats applicant restated his awards in essay form and read as a résumé with sentences, until he swapped it for a small honest story about tutoring his little brother. Georgia Tech's admission blog notes readers already have your accomplishments elsewhere. EssayCompass steers you toward a story only you could tell, not a repackaged brag sheet.

Many students also let someone else "fix" the essay until it no longer sounds like a teenager wrote it. Scenario: A parent and a paid editor polished a draft so heavily that the admissions reader flagged the too-adult voice as suspicious. Purdue's Writing Lab favors revision that preserves the writer's natural voice. EssayCompass coaches rather than rewrites, so every improvement still sounds authentically like you.
