5 Common Mistakes Made on Supplemental Essays

Supplemental college essays are university-specific, meaning that they are something you will write in addition to the Common Application Personal Statement, but they will only be sent to the specific institution that is asking the prompt. As such, these essays pack a lot of power: these are the college and universities’ best chance to really judge whether or not you’ll be a good fit for their specific campus community. These essay prompts can vary quite a bit between the various schools you are applying to, but the mistakes we see are pretty much universal. In this article, we’ll take a look at 5 Common Mistakes Made on Supplemental Essays.

5 Common Mistakes Made on Supplemental Essays

As you start to think about tackling your supplemental essays, here’s what not to do.

1. Underestimating the Importance of Supplemental Essays

If you stop and think about it, the supplemental essays for a college, are really the only place on your application where you can – quite literally – express your passion and excitement for wanting to attend their institution. As a result, it pays to have done your homework on what exactly it is that most excites you for your potential future there. 

When colleges and universities are reviewing your supplemental essays, they are looking for fit – will this student best utilize the education and resources of our institution, and are we the right school for them? It is your job to show them these answers through your detail-rich responses. If you do this correctly, you will leave no question that this school is the right fit for you. 

2. Utilizing a “Cut & Paste” Approach

A common mistake is to use a “cut and paste” approach, trying to recycle essays used from another school’s supplemental essay, and repurposing it to the new, and often times, very different prompt, on another application. While there are ways to recycle themes from essays, if you are copying and pasting your responses from one application’s essays and putting them in another application’s essays, I can guarantee you that you are lacking the specificity that a supplemental essay requires. 

I ask each of my students the same simple question: Could this essay be said about any other college you are applying to? If the answer is yes, then the essay is not specific enough. If you are able to copy and paste your essay and put it into a response for an entirely different application, your essay is not specific enough to be competitive in an applicant pool. 

3. Shallow Answers

Providing a shallow answer such as “my friends go there and they’ve told me great stories about how much fun they’re having,” or “I want to make a lot of money and graduates from your college tend to earn higher salaries,” is a way to quickly lose the interest of your reader. With how low acceptance rates are these days, if your supplemental essays are lacking depth – your reader will move on, simply put. 

4. Repeating Selling Points

Repeating the college’s selling points in their “Why Our College?” essay with no specific reason as to why you wish to attend. For example, “I want to go to ABC College because it has a great program in environmental science.”

A better answer would be:

“I read about interesting research being conducted by Professor Williams in your Environmental Sciences department on the effect of climate change on urban areas and the impact on their economies. I would love to participate in similar research and believe ABC College is at the forefront in this area of study.” 

Or 

“While visiting the campus I sat in on a class on how climate change is affecting the polar ice caps. The professor was engaging and the class responded with a lot of questions and lively discussion. This is the kind of environment I want to study in.”

In either of these examples, adding how you would contribute to the campus is key. “I’d love to apply what I’ve learned from my independent study on climate change to educating my peers on how we can lower our carbon footprint on campus.”

5. Proper Grammar, Spelling, And Vocabulary

As with all essays, appropriate grammar, spelling, and vocabulary are important. Using slang, “emojis”, uncommon terminologies, or abbreviations detract from the content and hurt your essay.
