You'll answer two to three prompts. The questions depend on your major and if you select a second choice.

Each response is about 150 words. You'll find the prompts in the "Writing" tab of our supplemental questions on the Common App.

If You're Applying to a Major:

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.

Q: How do I pick the right experience?

A:

  • Choose one specific, detailed story (depth over breadth).
  • Focus on an experience with a hands-on or leadership element.
  • Describe an obstacle you faced and how you overcame it.

Q: How should I structure my 150-word response?

A:

  • The Hook: Start with a specific moment. "When my server crashed..."
  • The Action: Describe your role and the challenges you faced.
  • The Reflection & Future: What did you learn, and how does it connect to your goals at UIUC?

Q: How can I make my essay memorable?

A:

  • Use discipline-specific vocabulary correctly.
  • Quantify your impact (e.g., "optimized by 30%," "managed a team of 5").
  • Show how you solved a problem and what new questions it raised for college.

Q: What are the common pitfalls?

A:

Sample Essay: Computer Science

When my school's website crashed during a virtual event, I volunteered to fix it. As the lead coder in our tech club, I dove into debugging the server, tracing the issue to a memory leak in our outdated CMS. With only hours before the event, I optimized the code and migrated the site to a cloud platform, boosting load speed by 40%. The challenge taught me to stay calm under pressure and deepened my love for problem-solving in coding. This experience solidified my goal to study Computer Science at UIUC, where I can explore courses like CS 421 and work in the Siebel Center to tackle real-world tech challenges.

Describe your personal and/or career goals after graduating from Illinois and how your selected first-choice major will help you achieve them.

Q: How do I link my major to my goal?

A:

  • Name specific UIUC courses, labs, or research opportunities.
  • Explain how a skill from your major solves part of your goal's problem.
  • Show a clear path from UIUC coursework to your career.

Q: How do I make my essay stand out?

A:

  • Focus on the problem you will solve, not just a job title.
  • Use a "Problem → Skill → Impact" structure for clarity.
  • Show that this goal is a logical next step from your past work.

Q: What are the common mistakes?

A:

Sample Essay: Mechanical Engineering

My goal is to design sustainable energy systems, specifically next-generation wind turbines that reduce costs by 20%. Mechanical Engineering at UIUC will equip me with the tools to achieve this. Courses like ME 470 will teach me finite element analysis to optimize turbine blade designs, while the Energy Systems Lab offers hands-on research opportunities. My high school project designing a small-scale turbine sparked this ambition, teaching me the physics of energy conversion. At UIUC, I aim to join Professor Smith’s renewable energy group to refine my skills and contribute to affordable clean energy solutions, addressing global energy challenges.

If You're Applying to Our Undeclared Program:

What are your academic interests? Please include 2-3 majors you're considering at Illinois and why.

Q: How do I select my majors?

A:

  • Connect majors through a core problem you want to solve.
  • Choose one primary and one complementary major.
  • Example: Computer Science + Psychology for UX/UI research.

Q: How do I show my interest is real?

A:

  • Connect your interest to a past project, class, or job.
  • Name a specific UIUC professor, lab, or course for each major.
  • Show why the unique combination of majors serves your goals.

Q: What are the common pitfalls?

A:

Sample Essay: Undeclared Program

I’m drawn to both Computer Science and Psychology at UIUC to explore human-computer interaction. My psychology class project analyzing user behavior on social media apps sparked my interest in how technology shapes cognition. UIUC’s CS 465 (User Interface Design) will teach me technical skills to build intuitive systems, while Psychology’s Brain and Cognition Lab will deepen my understanding of human perception. Additionally, I’m considering Bioengineering to address healthcare tech challenges, inspired by a hospital volunteering experience where I saw outdated medical interfaces. UIUC’s Bioengineering 415 will let me design user-friendly medical devices. These majors connect through my passion for improving technology’s human impact, and UIUC’s interdisciplinary resources make it the perfect place to explore this intersection.

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

Q: How do I connect classes to my goals?

A:

  • Focus on a specific project or concept from a class.
  • Explain the "spark"—how that moment shaped your goals.
  • Example: "My AP Bio project on CRISPR led me to pursue genetic engineering."

Q: How specific should my goals be?

A:

  • Describe the problem you want to solve, not just a job title.
  • Mention a specific industry or challenge you want to tackle.
  • Example: "Develop low-cost water filtration systems using nanotechnology."

Q: What are the common pitfalls?

A:

Sample Essay: Future Goals

My goal is to develop sustainable urban farming solutions to address food insecurity. My AP Environmental Science project on hydroponics showed me how technology can revolutionize agriculture, sparking my passion. The project required designing a low-cost system, teaching me resource optimization. At UIUC, I aim to explore Agricultural Engineering to learn advanced techniques like vertical farming. Courses like ABE 436 will provide practical skills in renewable energy systems, aligning with my vision of creating scalable, eco-friendly farms. My high school volunteer work at a community garden further solidified this goal, as I saw firsthand the impact of fresh produce access. I want to combine engineering and social impact to build systems that feed communities sustainably.

If You've Selected a Second-Choice Major:

Please explain your interest in your second-choice major or your overall academic or career goals.

Q: How do I link my first and second choices?

A:

  • Find a common theme or problem that connects both fields.
  • Example: "My interest in sustainable energy (1st: Engineering) is also supported by policy (2nd: Public Policy)."
  • Frame the second choice as a complementary, not random, interest.

Q: How do I make my interest seem authentic?

A:

  • Connect your second choice to a different class, project, or book.
  • Name a specific UIUC resource for your second choice (a lab, course, or professor).
  • This shows you have done your research beyond your primary major.

Q: What should I avoid in this essay?

A:

Sample Essay: Second-Choice Major (Public Policy)

My first-choice major, Environmental Engineering, reflects my passion for sustainable systems, but my second-choice major, Public Policy, complements this by addressing systemic change. My Model UN experience debating climate policies showed me how regulations shape environmental outcomes. I drafted a resolution on carbon taxes, learning the power of policy to drive innovation. UIUC’s POL 386 course on environmental policy will teach me to craft effective legislation, while the Institute for Sustainability, Energy, and Environment offers interdisciplinary research opportunities. Public Policy equips me to influence large-scale sustainability, ensuring my engineering solutions reach communities. Both majors align with my goal of creating equitable, green infrastructure, blending technical and societal approaches.

All the best!
