College Essay Mistakes to Avoid

By PursivaUpdated October 20266 min read

The draft that got better and worse

A senior finishes a first draft in August. It is about teaching his younger brother to ride the city bus alone: which stop, which transfer, what to do if he misses it. The draft is rough, and it sounds like him.

Over the next three weeks his English teacher, both parents and an older cousin each improve it. By September every sentence is clean. The bus route is gone, and in its place is a paragraph about responsibility.

He reads it again and cannot find a single error. It also no longer sounds like him.

What the essay is for

The essay is a smaller part of the decision than most families assume. In a NACAC survey of four-year colleges, 19% rated the essay as considerably important, against 77% for grades in college-prep courses. On its own, an essay rarely makes up for a weak record.

What it does is the one thing a transcript cannot do: it lets the reader hear the student. Admissions offices are consistent about this.

  • Yale asks applicants to use their own voice, and says an essay that does not sound like its writer cannot do its job as a personal statement.
  • MIT tells applicants plainly: "This is not a writing test."
  • Georgia Tech tells applicants to pause if they catch themselves writing what they think the college wants to hear.
  • Johns Hopkins publishes essays it admired, and most are stories from everyday life.

Almost every mistake below comes from forgetting this. The student tries to sound impressive, and the reader stops hearing a person.

Before writing

1. Picking the topic that sounds most impressive

Many students choose a topic because they think it will impress the reader, and not because they have much to say about it.

Take a student who spent one week on a service trip abroad and who also runs the Sunday shift at her family's laundromat. She writes about the trip, because it sounds like the bigger achievement. But she was there for seven days and remembers it only in general terms, so the essay stays general too. The laundromat is where her real stories are: the regular customers, the dryer only she knows how to restart, the first complaint she had to handle alone.

The fix: pick the topic you could talk about for twenty minutes without notes. If you have that much to say, you have an essay.

2. Repeating the activities list

The application already has a section where the student lists every activity. Some essays go through that same list again in full sentences: a paragraph about orchestra, a paragraph about the swim team, a paragraph about tutoring.

The reader finishes the essay knowing nothing they had not already read. The essay is the place for what a list cannot hold, such as why the student stayed in orchestra for three more years after being moved to the last chair.

The fix: choose one activity from the list and tell the story behind it that the list has no room for.

While writing

3. Describing what happened and skipping what it meant

In this mistake, the student tells a story in great detail and leaves almost no room for what they took from it.

Picture an essay about a championship soccer game. The student describes the first half, the goal the team gave up, the comeback and the final whistle, and that fills nearly the whole essay. Only the last two sentences say what the experience taught them, and it is usually something broad like "I learned to never give up." The reader now knows a lot about the game and very little about the student.

The fix: keep the story short. Use most of the essay to explain what changed afterwards in how you think or what you do, and give a specific example of that change.

4. Using words you would never say

Students often think a college essay should sound formal and grown-up, so they reach for long words.

A student who would normally say "I was scared to make the phone call" writes "I experienced considerable trepidation prior to initiating the call." The second version could have been written by anyone. Admissions readers are trying to hear a seventeen-year-old, and a sentence like this hides one.

The fix: read the draft out loud. Wherever you hear a sentence you would never say to a teacher you like, rewrite it the way you would say it.

5. Writing mostly about someone else

Students often write about a person they admire, such as a grandparent, a coach or a parent. That can work, but the essay is there to introduce the applicant.

Suppose a student writes about his grandfather, who arrived in a new country with nothing and built a business. If most of the essay tells the grandfather's story, the reader ends up admiring the grandfather and still does not know the student.

The fix: keep the person in the essay, but give most of the space to yourself: what you saw, what you did because of them, and what you decided.

After writing

6. Asking too many people to edit

This is what happened to the senior at the start of this article. Each of his four readers made a reasonable change. His teacher tightened the sentences, his parents replaced the bus details with a lesson about responsibility, and his cousin smoothed out the ending. No single change was wrong. Together they removed the parts that sounded like him.

The fix: choose one or two readers. Ask them to tell you where they got confused or lost interest, and then make the changes yourself.

7. Letting someone else write parts of it

Sometimes a parent rewrites a few paragraphs the night before the deadline. More and more often, a student asks an AI chatbot to produce a full draft. In both cases the essay stops sounding like a teenager, and admissions readers, who read a great many essays, tend to notice. Several colleges also say in their published policies that an AI-written essay is not the applicant's own work.

The fix: it is fine to get help thinking through ideas, and to ask for feedback. The sentences themselves should all be written by the student.

A quick check before submitting

  • Is this a topic the student has a lot to say about?
  • Does the essay tell the reader something that is not already in the rest of the application?
  • Does it spend more time on what the experience meant than on what happened?
  • Does it sound like the student when read out loud?
  • Is the student the main character?
  • Did the student write every sentence?

The feedback that helps

Look at the fixes together and one pattern runs through them. The essay improves when the student does more of the thinking, and it gets worse when other people do more of the writing.

So the useful reader is the one who asks questions. Where did you stop being interested? What did you want to know that I left out? Which sentence sounds least like me? Questions like these send the student back to the draft with something to do, and the next version is still theirs. Georgia Tech makes a related point about timing: it encourages applicants to seek help with reviewing after they have written their own draft.

How Pursiva's Essay coach works

Pursiva's Essay coach is built on that kind of feedback. It asks the student questions to draw out the story, reads what they have written, and tells them where the essay is working and where it loses the reader. It does not write a draft, a paragraph, an opening line or a replacement sentence.

It also knows the rest of the application. Because Pursiva starts from the student's theme, which it calls a Core Narrative, the coach can tell when an essay repeats what the activities already show, or drifts away from the story the other parts are telling.

The senior with the bus essay did not need four editors. He needed one reader to ask him why teaching his brother that bus route mattered so much, and then to let him write the answer himself.
