common app mistakes to avoid: the checklist I wish I had earlier

Common App mistakes to avoid honestly aren’t always the big dramatic ones. A lot of them are tiny, boring errors that make your application feel rushed even when your actual profile is strong. I made myself a simple pre-submit checklist, and it helped way more than another generic “how to apply to college” video.

Here’s the version I’d give a friend:

  • Read every section like a stranger. Not like the person who wrote it. Typos, repeated words, and weird phrasing show up fast when you switch perspective.
  • Check that your activities are specific. If an entry could describe literally anyone, rewrite it. Numbers, impact, leadership, and context matter.
  • Make sure your essay matches your actual voice. If one paragraph sounds 35 years old and the next sounds like you texting a friend, something is off.
  • Verify school-specific details. Wrong college name in a supplement is an obvious one, but also check majors, programs, and why-us details.
  • Look for accidental repetition. If your essay, activities, and additional info all repeat the same accomplishment, you’re wasting space.
  • Don’t misuse the additional information section. It should explain context, not become a second personal statement.
  • Preview the final PDF. Formatting can get weird, especially with pasted text and activity descriptions.
  • Double-check honors and dates. Grade levels, hours, positions, and timelines are easy to mess up when you’ve edited ten times.

My biggest takeaway: the strongest application plan is leaving time for one calm final review. Most common app mistakes to avoid happen when you’re submitting tired at 11:58 p.m.

If anyone wants, I can turn this into a shorter 10-minute submit checklist too.
