How to Write the Purdue University Supplemental Essays: Guide + Examples 2023/2024

Want to get a better sense of what Purdue is looking for? 

You’ll find an extensive, by-the-numbers look at Purdue’s offerings, from enrollment and tuition statistics to student life and financial aid information, on its Common Data Set. For deep insights into how this public research university envisions its role and how it wants to grow and evolve, read its Foundations of Excellence Report  (it’s 74 pages … yikes ... but you can skim). Reading through this will give you a strong idea of what Purdue values and how those values may be shifting. 

BUT, please don’t just copy and paste chunks of the plan into your essay because a) that’s plagiarism and it's basically an academic crime, and b) anyone could do that. 

Think about this: What aspects of Purdue’s plan speak to you? From reading the report, you would also discover that most students are admitted into one of Purdue’s highly individualized bachelor’s degree programs. So, if you have a clear sense on what you want to study and crave a strategic path to your future career, perhaps as an engineer, Purdue may be right for you! Think about what resonates with you and keep reading to find out how you can connect the dots.

How to Write Each Supplemental Essay Prompt for Purdue

How to Write the Purdue Supplemental Essay Prompt #1

How will opportunities at Purdue support your interests, both in and out of the classroom? (Respond in 100 words or fewer)

This is a very short variation on the “Why us?” prompt (an essay you’ll see quite a few schools require). 

Because it’s so short, the key will be finding 2-3 reasons that set Purdue apart from all the other schools you’re applying to and focusing on connecting to your academic and non-academic interests. 

Here’s the “Why us?” essay guide—in this case, the Cornell example is a good one, but it’s pretty long, so be sure to check out the Tufts example too. Here’s the short version of the guide, to (hopefully) pique your interest:

  • Spend 1 hr+ researching 5+ reasons why Purdue might be a great fit for you (ideally 2-3 of the reasons will be unique to Purdue and connect back to you).

  • Make a copy of this chart to map out your college research.

  • Create an outline for your essays based on either Approach 1, 2 (recommended), or 3 in our  full guide above.

  • Write a first draft!

As you write, try to  avoid these common mistakes: 

Six Common Mistakes Students Make on “Why Us?” Essays

Mistake #1: Writing about the school's size, location, reputation, weather, or ranking.

Mistake #2: Simply using emotional language to demonstrate fit.

Mistake #3: Screwing up the mascot, stadium, team colors, or names of any important people or places on campus.

Mistake #4: Parroting the brochures or website language.

Mistake #5: Describing traditions the school is well-known for.

Mistake #6: Thinking of this as only a "Why them" essay.

Below is a great sample essay for this prompt.

Example:

Recently, to become part of the “Smart Cities Initiative”, my hometown was awarded a $50 million grant. I wish to research robotics and autonomous sensing at Purdue’s Smart Informatix Laboratory. Specifically, mentorships such as “Smart Cities” (EPCS 10100) with Dr. Mohammad Jahanshahi will allow me to contribute to other prospective smart cities. Additionally, I am passionate about music, specifically the violin. Purdue’s philharmonic and symphony orchestras will satisfy my musical desire and introduce me to people who carry similar interests. Organizations like the Purdue Music Producers (PMP) will connect me to like-minded individuals who share my passion for music production.

Tips + Analysis

  1. If you have a specific academic focus in mind, consider including it. This student directly states his interest in researching robotics and autonomous sensing and takes it a step further by demonstrating he’s done his research and knows that Purdue has a Smart Informatix Laboratory. If you read the Provost’s Report linked at the top, you’d know that something unique about Purdue is its highly individualized bachelor’s degree programs and that most students are admitted into these. What that means is robotics + autonomous sensing is much better to reference than engineering or a more general interest. Dig through Purdue’s list of majors and get specific. 

  2. Pick an academic and a non-academic interest: The prompt asks you how Purdue will support “your interests, both in and out of the classroom,” so you want to make sure to pick at least one academic interest and one non-academic interest. Why? Because the golden rule of supplemental essays for college is to answer the question. This student combines robotics and autonomous sensing with an interest in smart cities (academic + research) and music, specifically violin. He takes it a step further by showing exactly where he’ll fit in as a violin player at Purdue: “Purdue’s philharmonic and symphony orchestras” and the Purdue Music Producers club. 

PSA: Try to avoid using the word “passionate,” as this is one of the most frequently used words in college essays.

Here’s another example for this prompt: 

Example: 

I hope to pursue a B.S in Computer Science, giving me the opportunity to take courses such as Data Mining and Machine Learning and Virtual Reality Technologies to elevate TeamBST, the social entrepreneurship venture I co-founded, to the global level at the RCHE.

I’m inspired by Professor Yexiang Xue’s research paper titled DESK, and I look forward to collaborating with him regarding the applications of machine learning in healthcare. While Purdue Mechatronics will give me the platform to push technological boundaries with like-minded tech enthusiasts, Boiler Baaz will introduce me to the Bollywood fanboy community.

How to Write the Purdue Supplemental Essay Prompt #2

Briefly discuss your reasons for pursuing the major you have selected. (Respond in 100 words or fewer.)

This is another super short variation of a classic supplemental essay: the “Why Major?” essay. 

You’ll find a step-by-step guide to writing this essay at this link, which we recommend reading through, but here’s the short version:

  • Step #1: Imagine a mini-movie of the moments that led you to your interest and create a simple, bullet-point outline.

  • Step #2: Put your moments (aka the “scenes” of your mini-movie) in chronological order, as it’ll help you see how your interests developed. It also makes it easier to write transitions.

  • Step #3: Decide if you want to include a specific thesis that explicitly states your central argument—in this case what you want to study and why. This thesis can be at the beginning, middle, or end of your essay.

  • Step #4: Write a draft!

Here’s an example for this prompt: 

Example: 

Having attended college Physics classes every Saturday for a year, I’ve embraced the wisdom from centuries-old mathematics and the vast potential of computers, a realization I can honor by pursuing Computer Science and Mathematics. Much of my interest in AI lies in its basis in the human brain, which I can pursue in a Psychology concentration. And Electrical Engineering allows me to connect the virtual world with the physical, as I currently do in robotics. Purdue will fuel my interdisciplinary interests that stem from my curiosity about connections between the materials and systems in the world around me. (98 words)

Tips + Analysis

  1. Consider naming your major at or near the start. You don’t need to be completely straightforward (“I plan to major in X”), but if you’re struggling to come up with a compelling hook, keep it simple and move forward. Value information over poetry. 

  2. Consider expanding (briefly) on what you’ll explore outside the major-specific classes you’ll take. Purdue has niche major/research opportunities, for example. This student also adds to his major in Computer Science and Mathematics with a concentration in Psychology and additional interests in Electrical Engineering, which shows he might be a good fit for Purdue’s highly specialized academic programs. 

  3. Briefly say why you became interested in this major. Following the “Why Major?” outline above will help with this step. This student tells us that his interest began after taking college physics classes every Saturday for a year (bonus points for taking this on outside of school). 

  4. If you have room, say how you’ll contribute to society in the future. Show how you’ll use the knowledge you’ll gain at Purdue to help make society (or your community, or the whole wide world) a better place in a specific way. This student plans to push the fields of AI and robotics further using his cross-disciplinary knowledge. 

We know, that’s a lot to do in just a few words. You don’t have to do all these things; just do your best.

Here’s another example for this prompt:

Bonus Example: 

Programming brings a unique logic-based aspect of creativity to my life. It provides me with a universal platform to express myself, where my hands do the talking. Syntax plays the role of grammar, and the various programming languages can be thought of as accents: different ways of achieving the same task. 

Over the years, I have grown fascinated by machine learning and robotics, and by their innumerable applications in our world. Through a B.S in Computer Science, I’ll strive to expand my knowledge in these fields, pushing the boundaries for technological innovation.

How to Write the Purdue Supplemental Essay Prompt #3

Briefly discuss your reasons for pursuing the alternate major you have selected. (Respond in 250 words or fewer.)

This is just like the prompt above—a “Why Major.” So see that previous section for guidance and examples + analysis.
