You will be writing 2-3 essays, depending on which category you fall into.
Each response is a max of 150 words.

UIUC Supplemental Essays — Applicants to a Major

Applying to a specific major at UIUC? You’ll need to respond to the following two prompts:

1) Explain, in detail, an experience you’ve had in the past 3 to 4 years related to your first-choice major. This can be an experience from an extracurricular activity, in a class you’ve taken, or through something else. (150 words)

Before you begin writing, you’ll want to do some brainstorming. Make a list of all experiences from the past 3-4 years that illustrate your passion and commitment to your first-choice major. Of those, which is most representative of your unique interests?

UIUC is not necessarily asking you to write about the in-class or extracurricular experience that led to you earning the most prestigious awards or holding the highest position of leadership. Instead, pick the option that will allow you to deliver the most memorable and authentic story to the admissions reader.

2) Describe your personal and/or career goals after graduating from UIUC and how your selected first-choice major will help you achieve them. (150 words)

This prompt shares some of the same elements of a traditional “Why Us?” essay, but UIUC is particularly interested in hearing about why the curriculum in your desired academic department is attractive to you. Below are some quick tips for writing an essay that will help your admissions cause:

Cite specific , , , , , , etc.
State why your chosen program is the perfect fit for you and why you are the perfect fit for it.
Offer insight into your future personal/academic/career goals. It’s okay if you’re not 100% sure what you want to do at age 25 (most teens are not). Feel free to speculate based on your current mindset and interests.

In summary, you’ll want to dedicate time to researching more about your prospective college/department and what makes it truly world-class. The more specific you can get here, the better your UIUC essays will be!

UIUC Supplemental Essays — Applicants to the Undeclared Program in the Division of General Studies

Applying to the Undeclared Program at UIUC? You’ll need to respond to the following two prompts:

1) What are your academic interests? Please include 2-3 majors you’re considering at Illinois and why. (150 words)

We recommend focusing the bulk of your response on your specific academic interests that relate to your major of choice. Whether it’s a general love for math/science or literature or a specific interest in aerospace engineering or an obsession with 19th-century French novels, use this opportunity to share what makes you tick, the ideas that keep you up at night, and what subject inspires you to dream big. Whether it’s falling down a Wikipedia rabbit hole about the nature of time or consuming thousands of hours of podcasts on game theory, this is a chance to illustrate the ways in which you are an obsessive learner with an endless thirst for information. The admissions reader should emerge from reading this essay with the sense that you are a sincerely curious young person with a strong intellectual drive.

Finally, be sure to connect these interests to 2-3 majors at Illinois and support your reasoning with school-specific offerings and resources, like , , , etc.

2) What are your future career or academic goals? You may include courses you took in high school and how these impacted your goals. (150 words)

Note that this question is a bit different than the one asked of students with a firm first-choice major. Still, we recommend providing as straightforward of an answer as possible. Although you may not have a firm idea of your academic goals if you are Undeclared, you can use your current academic interests (the ones explored in the question above) as well as past academic experiences to guide your answer. Similarly, if your career intentions are relatively unformed, use this space to share academic/career areas that may be of interest. Don’t sweat it if your plans are still in a nascent stage. This is normal for a 17 or 18-year-old, and UIUC will understand.

UIUC Supplemental Essays — Applicants to a Second-Choice Major (Including Undeclared)

If you select a second-choice major on UIUC’s application, you’ll also need to respond to a third prompt:

Please explain your interest in your second-choice major or your overall academic or career goals. (150 words)

See answer #1 for those selecting a major. You are essentially repeating this process for a different field. However, you probably don’t want to have two completely unrelated majors/career goals. For example, if your first choice was business and your second choice was economics, it’s easy to explain the relationship. If the fields are more disparate (e.g. Dance & Chemical Engineering), be sure to provide a thorough explanation.

How important are the essays at the University of Illinois Urbana-Champaign?

UIUC only labels two factors as being “very important” to the admissions process. Those factors are: the rigor of your high school coursework and your GPA. The essays are “important” to the application review. In fact, the essays are rated as being of equal importance to test scores, extracurricular activities, and talent/ability.
