You’ve got 150 characters. That’s it. It’s shorter than a tweet used to be. Most students treat the Common App activities section like a boring laundry list of things they did on Tuesday afternoons, but that’s a massive waste of real estate. Admissions officers at places like Yale or Georgia Tech spend about eight minutes—total—on your entire application. They aren’t reading your descriptions; they’re scanning them. If you don't hook them in the first three words of a description, you've basically vanished into the "maybe" pile.
Honestly, the pressure is weirdly high for something that feels so administrative. You're trying to condense four years of sweat, late-night rehearsals, and carpal tunnel from coding into ten tiny slots. It feels reductive. It is reductive. But if you know how to play the game, those ten slots can tell a more compelling story than your main essay ever could.
The Strategy Behind How to Fill Out Common App Activities Section
Stop thinking about "duties." Admissions officers don't care that a Treasurer "handled money." They know what a Treasurer does. They want to know what you did. Did you increase the club budget by 20%? Did you find a way to fundraise $5,000 for new uniforms during a global pandemic? That’s the difference between a filler activity and a standout one.
Most people mess up the "Role" and "Organization" boxes. They get repetitive. If the organization is "Varsity Basketball," don't put "Point Guard on the Varsity Basketball Team" as your position. Just put "Point Guard/Captain." Use that extra space. You have to be a bit of a ruthless editor here. Every character—including spaces—counts toward that 150-limit in the description.
Specifics beat adjectives every single time. "Organized many events for local youth" is 38 characters of nothing. It's fluff. Instead, try "Coordinated 4 weekly tutoring sessions for 50+ ESL students." See the difference? Numbers provide "social proof." They make your claims unverifiable but believable. If you say you were a "hard worker," I have to take your word for it. If you say you "worked 20 hours/week while maintaining a 4.0," I can see it for myself.
The Hierarchical Nightmare: What Goes First?
Order matters. A lot. You want your most "impressive" or time-intensive activities at the very top. Usually, this is the stuff that aligns with your "spike"—that one thing you’re better at than almost anyone else. If you’re a math whiz applying for Engineering, your Robotics lead role shouldn't be at number seven. It’s number one.
But wait. There’s a catch. Sometimes your most "impressive" thing isn't your most "meaningful" thing. If you spent 20 hours a week taking care of a younger sibling or working at a grocery store to help pay rent, that's incredibly important. Colleges, especially highly selective ones like Princeton or Stanford, have explicitly stated (often through the Turning the Tide initiative) that they value family contributions and work experience just as much as—if not more than—fancy summer programs in Europe.

Don't bury the real life stuff. It shows grit.
Quantifying the Unquantifiable
I see this all the time: "Member of Art Club. Created paintings. Participated in shows."
Boring.
Instead, think about the "Outcome." What changed because you were there? Maybe you "Curated gallery night for 200+ attendees; sold 5 personal pieces; raised $400 for art supplies." Even if you didn't win an award, you can quantify the effort. How many hours? How many people? How many meetings?
Using Action Verbs Like a Pro
Strong verbs are your best friends. Avoid "helped," "was," or "participated." They’re passive. They make it sound like you were just standing in the room while things happened around you. Use "Founded," "Spearheaded," "Managed," "Negotiated," or "Oversaw."
- Weak: Helped organize a car wash.
- Strong: Spearheaded car wash fundraiser; managed 15 volunteers to raise $1,200 for local animal shelter.
It's about ownership. You're the protagonist of this section.

The "Secret" 11th Activity and Other Hacks
Technically, you only get ten spots. But that’s not entirely true. If you have a massive project or a hobby that doesn't quite fit, you have the "Additional Information" section. Use it sparingly. If you just list an 11th activity because you couldn't pick your favorites, it looks like you can't prioritize. But if you have a research abstract or a complex portfolio, that's where it goes.
Also, don't ignore the "Time Spent" section. Be honest but accurate. If you say you spend 50 hours a week on activities and you're also taking 5 AP classes, the math doesn't add up. Admissions officers will notice if you claim there are 30 hours in your day. They’ve seen thousands of these. They know how long a sport takes.
Grouping Activities for Impact
If you have four different clubs that all do the same thing—like three different honors societies—consider grouping them. "National/Spanish/Math Honor Societies" can sometimes be one entry if you were just a general member in all of them. This frees up a slot for something unique, like that time you taught yourself how to restore vintage film cameras or your obsession with urban gardening.
Unique is better than "well-rounded." Colleges aren't looking for a well-rounded student; they're looking for a well-rounded class. They want a mix of specialists. If your Common App activities section shows you're the "Garden Guy" or the "Linux Expert," you're much more memorable than the kid who did ten clubs half-heartedly.
Dealing with the "Looming" Summer Break
Summer activities are a huge point of confusion. Do they count as the grade you just finished or the one you're starting? The Common App usually treats the summer after 10th grade as part of 10th grade. But honestly, as long as you're consistent, it's fine. What matters is the "Post-graduation" box. Only check that if you actually plan to keep doing the activity in college. It’s a subtle signal to the school that you’ll contribute to their campus life.
Real Example: The "Job" Description
Let's look at a cashier job at a local CVS.

Version A (The Mistake): "Worked at the register. Helped customers find items. Cleaned the store at night. Worked 15 hours a week."
Version B (The Expert Way):
"Trusted with opening/closing responsibilities; managed cash flow of ~$2k daily. Resolved 10+ customer disputes weekly. Mentored 3 new hires on POS system."
Version B shows leadership, responsibility, and "soft skills" without ever using those cheesy buzzwords. It’s about the evidence.
Common Mistakes That Kill Your Credibility
- The Acronym Trap: Don't assume an officer in California knows what "NYSSMA" or "FBLA" is. Some are famous, some aren't. If you use an acronym, make sure the full name is somewhere in the title or description if it's obscure.
- The "Everything" Student: Listing ten activities where you spent 1 hour a week looks like resume padding. It’s better to have six meaningful entries than ten shallow ones.
- Grammar Ghosting: Since people try to save space, they often stop using periods or use weird abbreviations. "Org. mtgs w/ rsch depts" is barely English. Keep it readable. Use semicolons to separate distinct thoughts.
- The "I" Problem: You don't need to say "I did this" or "I managed that." The context is already you. Start with the verb. "Managed," not "I managed."
Actionable Steps for Your Final Draft
First, grab a scratchpad or a Google Doc. Don't type directly into the Common App yet. It’s too easy to lose work or make a typo you can't see in that tiny text box.
- List everything. Don't filter yet. Write down the job you had for three weeks, the bird-watching hobby, and the varsity captaincy.
- Assign a "Value Score." Which ones show the most "impact"? Which ones show the most "commitment" (years involved)?
- Draft your 150-character descriptions. Use a character counter. You’ll be surprised how fast "President of the Student Government Association" eats up your space.
- Abbreviate intelligently. "Year" becomes "yr," "and" becomes "&," but don't overdo it. If it looks like a coded telegram from 1920, back off.
- The Peer Test. Show your descriptions to a friend who isn't in that club. If they don't understand what you actually did, an admissions officer won't either.
The Common App activities section is your chance to show you're a human who exists outside of a classroom. It’s the "evidence" section of your trial. If your essay says you’re a leader, this section needs to prove it with dates, numbers, and titles. Get specific, get gritty, and don't be afraid to show off the unconventional stuff. That weird hobby might be the thing that gets you in.
