The Common App: A Complete Walkthrough

The Common Application is used by over 1,000 colleges and universities. One application, multiple schools. But "common" doesn't mean simple. There are strategic decisions at every step that can strengthen or weaken your application. Here's how to handle each section.

Visual Walkthrough

Before diving into details, here's what the Common App actually looks like. These screenshots walk you through the account creation process so you know exactly what to expect.

Account Setup and Basics[1]Common Application, 2024–2025

The Common App opens August 1 each year at commonapp.org. You'll create an account with your legal name, email, and basic demographics. A few things to know upfront:

• Use a professional email. firstname.lastname@gmail.com, not soccerstar2008@yahoo.com.
• Your legal name must match your transcript. Nicknames go in the "preferred name" field.
• You can add up to 20 schools to your Common App dashboard.
• The application rolls over. If you create an account junior year to explore, your data carries into senior year.

The Seven Sections

1. Profile

Basic demographics: name, address, citizenship, language, fees. If you qualify for a fee waiver (free/reduced lunch, certain income thresholds, or counselor confirmation), request it here. It waives application fees at all Common App schools.

2. Family

Parents'/guardians' education, occupation, and marital status. This section provides context. If a parent didn't attend college, that's a meaningful data point for admissions. First-generation status is considered favorably at many schools.

3. Education

Your high school, GPA, class rank (if your school provides it), coursework, honors, and future plans. Key details:

• Report your GPA as your school calculates it. Don't convert to a 4.0 scale unless that's what your school uses.
• List honors and awards (up to 5). National-level recognition goes first, then state, regional, school.
• Course list: Some schools require you to self-report courses. Be accurate, admissions will cross-reference with your transcript.

4. Testing[2]FairTest, 2024

As of 2024–2025, this section is optional at many schools. The current picture:

If your scores strengthen your application (above the school's 50th percentile), submit them. If they don't, leave them out at test-optional schools. Simple.

5. Activities

This is the most strategic section of the entire application. You get 10 slots to list extracurricular activities, with 50 characters for the position/leadership title and 150 characters for the description. That's roughly one tweet per activity.

Activity List Strategy

Order matters. List activities by importance, not chronology. Your most significant activity goes first.

The 150-character description is brutally short. Focus on:

• Impact and scale: "Organized fundraiser raising $12,000 for local food bank" > "Helped with fundraising events"
• Specificity: Numbers, outcomes, scope
• Active verbs: Led, founded, designed, managed, created

Types that admissions values:

Depth over breadth. Three activities you're deeply invested in beat ten activities you joined for the resume. Admissions officers see through "resume padding" instantly.

Don't forget paid work and family responsibilities. If you work 20 hours/week or care for siblings, that's an activity. It's a significant one.

6. Writing (The Personal Essay)

You choose 1 of 7 prompts and write up to 650 words. The 2024–2025 prompts:

1. A background, identity, interest, or talent that is so meaningful you'd feel incomplete without it.
2. A lesson from a time you overcame an obstacle, failure, or setback.
3. A time you questioned or challenged a belief or idea.
4. A problem you've solved or would like to solve (any scale).
5. A personal growth moment triggered by an event or realization.
6. A topic, idea, or concept that makes you lose track of time.
7. Topic of your choice.[3]Common Application, 2024–2025

The real purpose: Admissions wants to hear your voice and understand how you think. The topic matters less than the insight. An essay about doing laundry can outperform an essay about a service trip to Guatemala if it reveals genuine self-awareness.

Prompt 7 is a trap and an opportunity. It's the "anything goes" option. Use it if you have a compelling story that doesn't fit the other prompts. Don't use it as a lazy fallback.

7. Additional Information

An optional section with 650 additional words. Use this for:

• Context that doesn't fit elsewhere: Family circumstances, health issues, school disruptions, gaps in your record
• COVID impact (still relevant for some applicants)
• Brief explanations of a bad grade or disciplinary issue
• NOT a second essay. Don't write another personal narrative here. This is for factual context.

School-Specific Supplements[1]Common Application, 2024–2025

Most selective schools require supplemental essays beyond the Common App essay. These are unique to each school and appear in your dashboard after you add the school to your list.

Common supplement types:

"Why this school?" is the most common and most important supplement. Be specific. Name actual courses, professors, programs, or traditions. "I love your diverse campus and great location" could apply to 50 schools and tells admissions nothing.

The Submission Timeline

Early Decision vs. Early Action

EDEarly Decision: a binding early application commitment acceptance rates are typically 10–20 percentage points higher than RD. At schools like Duke, Vanderbilt, and Northwestern, over 50% of the class is filled through ED. But it's binding: if admitted, you withdraw all other applications.[4]Common Data Sets, 2023–2024

Recommender Strategy

Most schools require 1–2 teacher recommendations plus a counselor letter. Choose recommenders who:

• Know you well (not just gave you an A)
• Taught you in core academic subjects (junior year teachers are ideal)
• Can speak to your character, not just your grades
• Have time to write thoughtfully, ask by September at the latest

Common Mistakes

1. Submitting without proofreading supplements. Nothing kills an application faster than writing "I've always dreamed of attending Columbia" in your Yale supplement.
2. Underusing the Additional Information section. If there's context admissions should know, put it here.
3. Generic activity descriptions. 150 characters is tight, make every word specific and impactful.
4. Waiting until December to write RDRegular Decision: standard application timeline with decisions by spring supplements. You'll have 5–15 supplements due in early January. Start early.
5. Not requesting fee waivers. If you qualify, use them. There's no stigma.

The Common App is a tool. Like any tool, it works best when you understand how each piece functions and make deliberate choices throughout. Start early, be specific, and let your actual self come through.
