How to Fill Out the Common App: The 7 Decisions That Actually Matter

The Common App opened on August 1, and by now you've probably found one of the very long guides that walks you through all nine sections in order. You don't really need that. The nine sections are visible on the screen — you can see that there's a Family section and what it wants.

What the form doesn't tell you is which of its blanks are load-bearing. Most of the Common App is data entry: your address, your counselor's email, your parents' education. Get it right, move on. But roughly a dozen fields are actual decisions, where two students with identical transcripts can fill out the same form and read completely differently to the same admissions officer.

Those are the ones worth your attention. Here are the seven that matter most, and how we'd tell you to make each call.

First: What Changed for 2026–27 (and Last Cycle)

Skip this if you're reading in a later cycle — this is the part of the Common App that turns over annually.

The genuinely useful change this year: the position/leadership title field in the Activities section is now optional. Informal roles finally have a home. You no longer have to invent a title like "Founding Member" for a thing where you were, honestly, just the person who showed up every week and did the work. The section has also been renamed Activities and experiences.

Two changes from last cycle (2025–26) still catch families working from older advice. First, the Additional Information box was cut from 650 words to 300. Common App noted that most students were already writing well under 300 words. Three hundred words is enough to explain a circumstance. It is not enough to make a second case for yourself, and you should stop trying.

Second, hardship context has its own dedicated question, separate from Additional Information — the descendant of the COVID-era "community disruption" question, broadened to cover things like financial strain, family caregiving obligations, health, housing instability, and discrimination. If you have real context of that kind, it belongs there, not in the general-purpose box.

Everything else this cycle — new member colleges, more sibling fields, a few additional reportable AP exams — is real but won't change a single decision you make.

Decision 1: Which 10 Activities Make the List, and in What Order

You get 10 slots. Each one gives you 100 characters for the organization, 50 for your position, and 150 characters to describe what you actually did.

Those limits are the whole strategy, and this is where most applications quietly lose ground.

Do not fill all ten just because there are ten. Six real activities read as a person with commitments. Ten activities where the last four are "attended two meetings" read as padding, and they actively dilute the six that matter. An admissions reader spends a few minutes on your entire file. Every weak slot spends some of that on nothing.

Order is a decision, not a default. The list is read top-down and attention decays as it goes. Slot 1 gets read carefully; slot 9 gets skimmed. So the top of your list should be whatever best supports the story the rest of your application is telling — usually your deepest commitment, not your most impressive-sounding title. If your signature strength is research and you're also class treasurer, research goes first.

Then spend the 150 characters properly. The single most common mistake is using them on adjectives. Compare:

• "Passionate member of our school's award-winning robotics team, working hard with dedicated teammates on competitive projects." — 124 characters that convey nothing. Every word is a claim about your attitude.
• "Built drivetrain for competition bot; led 4 underclassmen on machining; team placed 3rd at state, 42 teams." — same space, and now a reader knows what you did, who you were responsible for, and what came of it.

Cut every adjective about yourself. Keep verbs, numbers, and outcomes. If a phrase would be true of anyone in the club, delete it and use the space for something that's only true of you.

Decision 2: Honors or Activities?

Separate from Activities, you get 5 honors slots at 100 characters each, and this is free real estate most students misuse.

The distinction is simple once you see it: the award goes in Honors, the work goes in Activities. If you won a state science fair, "State Science Fair, 2nd place, Physics" belongs in Honors — which frees a full activity slot to describe the eighteen months of research that got you there. Students who put the award itself in an activity slot are paying 150 characters for a line that needs 40.

Honors is for academic and merit recognition. Non-academic recognition — an athletic award, an arts prize — generally lives with the relevant activity instead. And the same rule as Activities applies: five weak honors are worse than two real ones.

Decision 3: Whether to Waive Your FERPA Rights

The form will ask whether you waive your right to read your recommendation letters later. It's a genuine legal choice, presented with no guidance, and you have to make it before you can invite recommenders.

Waive it. Nearly every applicant does, colleges expect it, and counselors advise it almost universally — because a letter written in confidence is read as candid, and a letter the student can later read is discounted. Declining doesn't get you anything useful; it just puts a small question mark on every letter in your file.

The real work here isn't the checkbox. It's that you should never be in a position where you'd want to read the letter. If you're nervous about what a teacher will say, the answer is to pick a different teacher — and to give whoever you pick real material to work from, early. A recommender asked in September with a list of specifics writes a different letter than one asked in a hallway in late October.

Decision 4: Whether to Use Additional Information at All

Default to leaving it blank.

That advice surprises people, because an empty box feels like a wasted opportunity. It isn't. Additional Information exists to explain things the rest of your application can't account for — a semester of bad grades with a reason behind it, an unusual curriculum or grading scale, a transfer mid-high-school, a gap in activities because you were working 20 hours a week or caring for a family member.

That's the test: does something in my file look worse or stranger than it is without an explanation? If yes, explain it there, plainly, in a few sentences. If no, leave it empty. Adding a fourth essay's worth of accomplishments you already listed is one of the few things in the Common App that can genuinely count against you, because it reads as not knowing what's relevant — and at 300 words, the box now openly says it isn't for that.

Two practical notes. Explain, don't plead: "Two months of missed school during my mother's hospitalization in spring of 10th grade" does the work; a paragraph about resilience does not. And if the thing you need to explain is hardship rather than a technicality, use the separate circumstances section built for it.

Decision 5: Whether to Self-Report Your Test Scores

Test-optional does not mean test-blind, and this is the decision students most often make once for every school when it should be made school by school.

The rough rule: if your score lands at or above the middle 50% range for a school's admitted students, report it. If it's below, don't. Those ranges are published, and they're the actual benchmark — not your feelings about the number, and not what your friends scored.

Two things complicate it in ways worth knowing. First, at some test-optional schools a strong score still helps, because it corroborates a transcript from a high school the reader doesn't know well. Second, and more important for most families: merit aid formulas at many schools still use test scores even where admission is test-optional. A score that's neutral for admission can be worth real money. That's a good reason to send a solid score to a school where you're chasing merit, and a good reason to weigh scores against what each school will actually cost you rather than in isolation.

Decision 6: The Early Decision Checkbox Is a Financial Decision

Somewhere in a school's questions there's an option to apply Early Decision. It looks like a scheduling preference. It's a contract.

ED is binding. You sign it, your parent signs it, your counselor signs it, and if you're admitted you withdraw your other applications and enroll. Which means the checkbox does something no other field in the Common App does: it gives up your ability to compare financial aid offers in April.

For a family that has run the school's net price calculator, is confident the aid will work, and is genuinely certain this is the first choice, ED is a real advantage and worth using. For a family that needs to weigh three offers against each other to decide what's affordable, an ED acceptance to an unaffordable school is the worst outcome in the entire process — you've won and you still can't go.

So the honest sequence is: figure out the money first, then decide about ED. Not the other way around. And if you're not certain enough to be bound, Early Action gets you most of the timing benefit with none of the commitment. This is exactly the decision that should be settled while your college list is still being built, not in the last week of October.

Decision 7: What Order to Do It In

The Common App isn't graded on how you sequence it, but sequencing is what determines whether you finish calmly or in a panic. What we'd tell you:

• Do the boring sections first, in one sitting. Profile, Family, Education, Testing. They're pure data entry, they're the same for every school, and getting them done early gets them out of your head. Check your own email address twice — a typo there is a genuinely bad, genuinely common way to lose contact with a college.
• Invite recommenders next, before the essays. Their timeline is the one you don't control, and it's the constraint that bites in late October.
• Then the personal essay, which is a separate project from the form and deserves its own weeks. We wrote about that process in How to Write a College Essay That Sounds Like You, and about where AI helps and where it quietly hurts you while drafting it.
• Activities and honors after the essay, not before. Once you know what story your essay tells, the ordering and phrasing decisions in Decisions 1 and 2 get much easier.
• School-specific questions and supplements last — they're the part that multiplies by the number of schools, and the part most likely to expand to fill whatever time is left.

One mechanical note that saves grief: it's one account for every school, and most of your core sections carry forward from year to year, so there's no reason to duplicate work — but school-specific answers do not, and each school still has its own deadline and its own requirements. Build the checklist per school, not once globally.

The Part No Form Can Decide

You'll notice that five of these seven aren't questions about the Common App at all. They're questions about you: which commitment is really yours, whether a score helps or hurts in your case, whether your family can absorb a binding commitment, whether something in your file needs explaining.

Every guide on the internet can tell you that Activities has ten slots. None of them can tell you which six of your things belong there, or in what order, because that depends on the rest of your application and on what you're actually trying to say. That gap is the whole reason expert judgment still matters even now that the admissions information itself is free.

And if you're reading this in early August with the form open in another tab: you're right on time. Here's the rest of the game plan for the next few weeks.
