Writing the University of Southern California supplemental essays can feel like a puzzle, especially when you’re trying to figure out what each question is really asking. USC is an academically rigorous, highly selective school, and its supplemental prompts are designed to highlight the students who have done their homework—those who understand their academic goals, know why USC is the right environment for them, and can communicate that fit clearly. In this guide, we’ll walk through the USC supplemental essays, break down each prompt, and give you practical strategies to write responses that are thoughtful, specific, and genuinely reflective of who you are.
Why Do Colleges Require Supplemental Essays?
When you’re preparing your USC supplemental essays, it helps to understand the bigger picture. USC isn’t asking you to write extra paragraphs just to make your life harder; they’re using these supplementals to learn things your GPA, test scores, and personal statement can’t fully reveal. Your academic record shows your achievements. Your personal statement shows your voice and values. But your supplemental essays show something else entirely: how intentionally you’re making your college choices.
The USC supplemental essays are meant to to evaluate how well you understand your academic interests, how well you understand the university itself, and whether the two fit together in a way that suggests you’ll thrive there. Admissions readers want evidence that your decisions are informed, thoughtful, and grounded in real experiences—not random guesses or generic enthusiasm.
That’s why simply submitting your GPA, transcript, test scores, recommendations, activities, and personal statement isn’t enough. Those materials provide a foundation, but supplemental essays fill in the gaps. They give colleges the additional information they need to determine whether you’re a strong match for the school.
For USC and many other institutions, this often comes down to two essential questions:
How well do you know your major?
How well do you know the school?
Behind the scenes, colleges care a lot about maintaining high graduation rates. Departments want students who are likely to stay in the major. That’s one reason “Why School” and “Why Major” prompts are so common. A student with years of experience in STEM projects, competitions, or hobbies is statistically more likely to stick with a STEM major than someone who picked it because it “sounds practical.” And even if you have that deep background, USC still wants to know: Why here? What makes USC the right place for you to continue that work? Showing that you understand USC’s specific offerings demonstrates informed decision-making—something admissions readers trust.

How to Write the USC Supplemental Essays
To tackle the USC supplemental essays effectively, you’ll need to know how each prompt is designed to reveal a different side of who you are.
Prompt 1: Describe how you plan to pursue your academic interests and why you want to explore them at USC specifically. Please feel free to address your first and second-choice major selections.
This is a classic “Why Major” prompt. And before we get into how to write it, it helps to remember that supplemental essays are carefully constructed to get specific information USC has decided is useful. They’re not asking you to improvise “vibes” or gesture vaguely at your interests. They want direct answers to the components embedded in the question. That means it’s vital to answer the prompt—not just generally, but in full.
A simple and effective strategy is to break the prompt into bullets. This ensures you answer every part:
- Describe how you plan to pursue your academic interests
- Describe why you want to explore them at USC specifically
- (Optional but encouraged) Address your first and second choice majors
Because the prompt mentions your first and second choice majors—and because you only have 250 words—you should treat those majors as your “academic interests.” In effect, the prompt asks you to:
- Describe how you plan to pursue your first and second choice majors.
- Describe why you want to explore your first and second choice majors at USC.
A straightforward template looks like this:
Provide 2–4 examples explaining how you will pursue your first and second choice majors.
Provide 2–4 examples explaining why you want to explore those majors at USC.
When I say “examples,” I don’t mean general statements like “world-class opportunities.” You need specific interests paired with proper nouns related to USC. For example:
I’m particularly interested in how AI can cross-reference medical databases to identify off-label uses of generic drugs. USC’s XYZ course in Translational Medicine would give me the perfect entry point into that field…
This works because it pairs your specific academic interest with something USC uniquely offers.
Compare that to:
As a world-class university with a top 10 ranked program, USC provides copious opportunities to explore AI in medicine through dozens of courses…
This is brochure language that could apply to almost any school.
Another common misstep is naming a professor or program without explaining why you care:
At USC, the courses are taught by amazing faculty, like Dr. ABC, and there are lots of internships, such as the XYZ program…
Without a personal connection, these details still feel generic.
To succeed on the USC supplementals, each example must combine USC specificity with your personal reasoning.
Let’s revisit the structure:
Provide 2–4 examples explaining how you’ll pursue your majors.
Example: I’m particularly interested in how AI can be used to cross-reference medical databases… USC’s XYZ course…
Provide 2–4 examples explaining why USC is the right place for you.
Example: USC’s academic philosophy prioritizes science that directly benefits local communities; the XYZ event held by USC med students last year reminded me of my own senior project…
One effective way to start writing this essay is to brainstorm your examples first. Don’t worry about paragraph structure at the beginning—just list your interests, then find USC matches, and build the paragraphs afterward.
Prompt 2: Short Answers
- Describe yourself in three words.
- What is your favorite snack? (100 characters)
- Best movie of all time: (100 characters)
- Dream job: (100 characters)
- If your life had a theme song, what would it be? (100 characters)
- Dream trip: (100 characters)
- What TV show will you binge watch next? (100 characters)
- Which well-known person or fictional character would be your ideal roommate? (100 characters)
- Favorite book: (100 characters)
- If you could teach a class on any topic, what would it be? (100 characters)
The instinct—especially after writing longer essays—is to overthink these. But there’s no trick here. You should lean into authenticity. And remember, USC sees your entire application. If you say your favorite movie is Grapes of Wrath and your favorite book is War and Peace, they’ll notice if that seems disconnected from your writing style or the rest of your application.
That said, you shouldn’t under-think them either. Students sometimes see these as a “break” and rush through. Instead, try answering each question honestly, then revisit your responses and ask yourself:
- Is this actually true?
- Does this reflect something real about me?
- Is this genuinely my dream trip, or just the first destination that popped into my head?
- Is this dream job meaningful to me, or simply high-paying?
- Is this my actual favorite book, or just the most impressive one?
These short answers create a quick, vivid snapshot of your personality. If you treat each prompt as a real opportunity rather than a throwaway line, the portrait you create will feel authentic, memorable, and uniquely yours.
Conclusion
The USC supplemental essays aren’t meant to trick you—they’re meant to help admissions understand how you think, what you value, and why USC is a place where you’ll thrive. If you focus on specificity, personal tie-ins, and honest reflection, you’ll give USC exactly what they’re looking for and present yourself as a thoughtful, intentional applicant.
