The 10 Most Common College Essay Mistakes (And How to Fix Them)
How to turn a rejection-worthy essay into one that gets you accepted
Zyra AI • February 14, 2026
You've rewritten your Common App essay seven times. You've asked your English teacher, your mom, and your best friend to read it. And yet somehow, it still feels... off.
Here's what nobody tells you: most students make the exact same mistakes in their college essays. Not because they're bad writers, but because they're trying too hard to sound like what they think admissions officers want to hear.
I've read thousands of college essays, both as a former admissions reader and through working with students at Zyra. The patterns are impossible to miss. The good news? Once you know what to avoid, fixing these mistakes is straightforward. The better news? Most of your competition won't read this article.
Let's get into it.
Mistake #1: Starting With a Quote, Definition, or Statistic
What it looks like:
"As Nelson Mandela once said, 'Education is the most powerful weapon which you can use to change the world.' This quote has always resonated with me..."
Or:
"According to Merriam-Webster, leadership is defined as..."
Why it's a problem:
Admissions officers see this opener on literally 30-40% of essays. It's become an instant eye-roll. Worse, you're wasting your most valuable real estate - those crucial first 50 words - on someone else's words, not yours.
How to fix it:
Start with a moment. A scene. Something that happened to you. Drop the reader directly into your story without preamble.
Instead of this: "'You miss 100% of the shots you don't take.' This Wayne Gretzky quote inspired me to try out for the debate team..."
Try this: "My hands were shaking so badly I dropped my note cards all over the auditorium floor. Two hundred people watched me scramble to pick them up. I had thirty seconds before I had to deliver my first debate."
See the difference? One is generic motivation-poster stuff. The other is you, in a specific moment, with stakes.
Mistake #2: The Thesaurus Attack
What it looks like:
"I have always been an individual who possesses an insatiable predilection for the acquisition of knowledge and the perpetual expansion of my intellectual horizons."
Why it's a problem:
You don't talk like this. Your friends don't talk like this. Admissions officers know you pulled out a thesaurus, and it makes you sound less authentic, not more impressive.
There's a student I worked with at Zyra who wrote: "I experienced an epiphany of monumental proportions." When I asked what she really meant, she said: "I finally got it." That's the version that should've been in her essay.
How to fix it:
Read your essay out loud. If you stumble over a word or wouldn't say it in normal conversation, replace it. Your essay should sound like you at your most articulate - not like you swallowed a dictionary.
Word swaps that actually work:
"Utilize" → "use"
"Endeavor" → "try"
"Plethora" → "many" or just say the number
"Myriad" → "countless" or "many."
"Facilitate" → "help"
Simple, clear language isn't less sophisticated. It's more powerful.
Mistake #3: The Resume Essay
What it looks like:
"I am president of the debate club, captain of the varsity tennis team, and founder of a nonprofit that has served over 500 students. I also volunteer at the local hospital and maintain a 4.0 GPA while taking five AP classes."
Why it's a problem:
Colleges already have your resume. They can see your activities list. Your essay isn't the place to repeat information they already know - it's the place to help them understand who you are beyond the bullet points.
How to fix it:
Pick ONE activity, experience, or moment and go deep. Don't tell them you're president of three clubs. Tell them about the one night you stayed up until 2am redesigning your club's entire budget because you realized the treasurer had been calculating wrong for months.
Depth beats breadth every single time.
The test: If another student with your same activities could write your essay by just swapping in their name, it's too generic. Add the details only you would know.
Mistake #4: Trying to Sound "Deep" or Philosophical
What it looks like:
"Life is a journey filled with unexpected twists and turns. We are all searching for meaning in this vast universe, seeking to understand our place in the grand tapestry of existence."
Why it's a problem:
This sounds like you're trying to write the opening to a self-help book, not tell a college who you are. Vague philosophical musings don't reveal anything about you specifically.
How to fix it:
Ground your "deep thoughts" in concrete experiences. If you learned something meaningful, show the moment you learned it - don't just state the lesson.
Instead of this: "Failure is the greatest teacher, and through adversity, we discover our true strength."
Try this: "I failed my driver's test three times. The third time, I cried in the DMV parking lot while my dad pretended not to notice. But on attempt number four, when I parallel parked perfectly on the first try, I realized something: I'm allowed to be bad at things before I'm good at them."
Same lesson. Infinitely more memorable.
Mistake #5: The Trauma Dump
What it looks like:
Opening with a detailed description of a parent's death, a serious illness, abuse, or other significant trauma - especially if the essay focuses primarily on the hardship rather than growth or insight.
Why it's a problem:
I want to be really careful here: your experiences are valid, and if something difficult shaped you, you're allowed to write about it. But here's what happens too often - students think the "bigger" the hardship, the more impressive the essay. That's not true.
Admissions officers are reading these essays at 11pm after already reading 50 others. If your essay is entirely focused on pain without showing resilience, reflection, or growth, it can actually work against you. They're not therapists - they're trying to assess if you'll thrive on their campus.
How to fix it:
If you're writing about something difficult, spend 20% of the essay on what happened and 80% on what you did with it, what you learned, or how it changed your perspective.
Also: you can write about smaller challenges. Not everything needs to be life-or-death. The essay about learning to cook after your mom started working nights can be just as powerful as the essay about overcoming a serious illness - if it reveals who you are.
Zyra's AI can help here: Upload your draft and ask: "Does this essay focus too much on the challenge and not enough on my growth?" You'll get specific feedback on rebalancing.
Mistake #6: Ending With "And That's Why I Want to Go to [College Name]"
What it looks like:
"...and this experience taught me the importance of perseverance, which is why I know I would thrive at Northwestern University."
Why it's a problem:
This is your personal statement, not your "Why Us?" essay. Those are two different prompts. Shoehorning a college's name into your Common App essay feels forced and doesn't add value.
Worse: if you forget to change the college name when you submit to different schools (yes, this happens), you've just told Yale you want to go to Princeton.
How to fix it:
End your personal statement by reflecting on who you are now or what you value, not by name-dropping a school.
Instead of this: "This taught me to value community, which is why I'm excited to join the vibrant campus life at USC."
Try this: "Now when I see someone sitting alone at lunch, I don't hesitate. I know what it's like to need someone to notice you. I pull up a chair."
The second version tells them who you are. That's what they're looking for.
Mistake #7: The "I've Always Known" Essay
What it looks like:
"Ever since I was five years old, I've known I wanted to be a doctor. I've spent my entire life working toward this goal."
Why it's a problem:
First, it's probably not true. You didn't emerge from the womb with a stethoscope. Second, even if you genuinely did know at five, the essay that just restates "I've always wanted this" doesn't show growth, change, or self-discovery.
Colleges want to see that you think, question, and evolve - not that you locked in a path at kindergarten and never reconsidered it.
How to fix it:
Show the moment you questioned, refined, or deepened your understanding of what you want. Doubt and discovery are more interesting than unwavering certainty.
Instead of this: "I've wanted to be an engineer since I was seven years old when my dad showed me how bridges work."
Try this: "I thought I wanted to be an engineer because I liked building things. Then I spent a summer actually working with engineers and realized I hated sitting at a computer all day. What I actually loved was the moment when we'd test a prototype and it worked. That's when I knew I wanted to study design."
Change shows maturity. Colleges love maturity.
Mistake #8: Telling Instead of Showing
What it looks like:
"I am a hard worker. I am passionate about science. I am a natural leader who cares deeply about my community."
Why it's a problem:
Anyone can say these things. Your essay needs to prove them through specific examples, not just state them as facts.
This is the #1 piece of feedback I give through Zyra's essay review tool: "Show me this. Don't tell me."
How to fix it:
Replace every claim with a scene that demonstrates it.
Instead of this: "I am passionate about environmental justice."
Try this: "I spent three months learning to read water quality reports so I could explain to my city council exactly why the lead levels in our school's drinking fountains were illegal. They didn't listen until I brought 40 students to a public hearing."
See how the second version proves passion without ever using the word?
Mistake #9: The Essay That Could Apply to Anyone
What it looks like:
"Playing soccer taught me teamwork, discipline, and perseverance. These skills will help me succeed in college and beyond."
Why it's a problem:
Literally thousands of other students play soccer. Thousands of them learned teamwork. This essay has nothing in it that makes it yours.
How to fix it:
Find the specific, weird, personal detail that only you would include.
Generic version: "Debate taught me how to think critically and argue persuasively."
Specific version: "The first time I won a debate round, my opponent's mom came up to me afterward and said, 'That was brutal.' I didn't know if she was complimenting me or threatening me. I'm still not sure. But I learned that day that making a good argument sometimes means making people uncomfortable - and I'm okay with that."
The specific version tells a story. The generic version could be written by AI. In fact, I tested this - I put the generic version into ChatGPT and it spit out almost the exact same thing.
Pro tip: Use Zyra to test this. Upload your essay and ask: "Could another student with my same activities write this essay by just changing the names?" If the answer is yes, add more personal details.
Mistake #10: Ignoring the Word Count
What it looks like:
Writing 1,200 words when the limit is 650. Or writing 400 words and calling it done.
Why it's a problem:
Going over makes you look like you can't follow directions (not a great first impression). Going way under makes it look like you didn't put in effort or didn't have enough to say.
How to fix it:
The Common App limit is 650 words. Aim for 550-650. That's the sweet spot.
If you're under 500 words, you probably need to add more specific details and examples. If you're over 700, you're including unnecessary information - cut anything that doesn't directly support your main point.
The test: Read your essay and remove every sentence that doesn't either (a) tell a story, (b) reveal something about you, or (c) show growth/reflection. What's left should be close to 600 words.
Bonus: The Biggest Mistake Nobody Talks About
Not getting feedback from the right people.
Your mom will tell you it's perfect because she loves you. Your English teacher will fix your grammar but might not understand what colleges are looking for. Your friend will say "it's good" because they have their own essay to worry about.
You need feedback from someone who knows what admissions officers actually care about.
That's where Zyra comes in. Upload your essay and get specific, actionable feedback in minutes - not vague praise or grammar corrections, but real guidance on structure, storytelling, and authenticity. It's like having an admissions expert available 24/7, except you don't need to pay $10,000 for a private counselor.
How to Actually Fix Your Essay (Step-by-Step)
Now that you know what not to do, here's what to do instead:
Step 1: Read your essay out loud. If you stumble, cringe, or sound like a robot, rewrite that section in your actual voice.
Step 2: Cut the first paragraph. I'm serious. Try it. Often, your real essay starts in paragraph two - paragraph one is just warm-up.
Step 3: Find your most specific detail. The moment only you would know. Build around that.
Step 4: Show, don't tell. Replace every claim ("I'm passionate about X") with a story that proves it.
Step 5: Get real feedback. From someone who knows college admissions. Or from Zyra's AI essay reviewer, which can analyze your essay for authenticity, specificity, and structure in under 5 minutes.
Concluding Thoughts
Here's the truth: writing a great college essay isn't about being the most talented writer or having the most dramatic story. It's about being honest, specific, and reflective.
Most students overthink it. They try to sound impressive instead of interesting. They list achievements instead of sharing who they are. They write what they think colleges want to hear instead of what they actually need to say.
Your essay doesn't have to be perfect. It has to be you.
So go back to your draft. Read it with fresh eyes. Ask yourself: would my friends recognize me in this essay? Would they hear my voice? If the answer is no, you've got work to do.
And if you need help getting there, Zyra's AI is trained specifically on what makes college essays work - not just what makes them grammatically correct. We help you write essays that sound like you at your best, not like a college admissions robot.
Because at the end of the day, colleges aren't just looking for students who can write. They're looking for students who can think, reflect, and be honest about who they are.
Be that student. Your essay is the one place in your application where you get to be fully, authentically yourself. Don't waste it trying to be someone you're not.
