By Appffeine Research Team · Updated February 11, 2026

Before You Start

Before creating your Common App account, gather:

  • Social Security Number (optional but recommended)
  • Email address you'll use throughout the process
  • High school CEEB code (your counselor has this)
  • List of activities and their hours/weeks
  • Testing information (SAT, ACT scores)
  • Parent/guardian information (education, employment)

Creating Your Account

  • Go to commonapp.org and click "Create an Account"
  • Choose "First Year Student"
  • Enter your personal information
  • Create a secure password (you'll use this for months)
  • Verify your email address
Tip: Use an email address you check daily. You'll receive important updates and school communications here.

Filling Out Each Section

Profile Tab

Your basic information. Most fields are straightforward:
  • Name, address, phone
  • Demographics (optional but recommended for aid)
  • Citizenship and language information

Family Tab

Parent/guardian details. Common App asks for:
  • Parents' names, education level, and occupation
  • Sibling information
  • Family financial situation (broad strokes)

Education Tab

Your academic record:
  • High school name and graduation date
  • GPA and class rank (if applicable)
  • Honors and AP/IB courses
  • Any college courses taken
What to track separately: How does your academic profile match each school's typical admitted student? Appffeine's college search shows acceptance rates and average test scores so you can gauge your fit.

Testing Tab

  • SAT, ACT, AP, IB, and other test scores
  • You can choose to self-report or send official scores
  • Check each school's test-optional policy

Activities Tab

You get 10 activity slots with 150-character descriptions. Prioritize:
  • Activities with leadership roles
  • Long-term commitments (4 years)
  • Activities related to your intended major
  • Community service and work experience

Writing (Personal Essay)

Choose one of the Common App prompts and write 250-650 words. This essay goes to every school.

What to track separately: Many schools also require supplemental essays. Track essay drafts, revision deadlines, and feedback from reviewers. Appffeine lets you set milestones for each essay: First Draft, Get Feedback, Final Ready.

Adding Schools to Your List

Search for schools and add up to 20. For each school, check:

  • Application deadline (ED, EA, RD)
  • Required supplements
  • Application fee (and fee waiver eligibility)
What to track separately: Adding a school to Common App doesn't track its financial aid deadlines, housing deadlines, or scholarship opportunities. Add these to your Appffeine dashboard for complete visibility.

Supplemental Essays

Many schools require additional essays beyond the main Common App essay. These are school-specific and often ask:

  • "Why this school?"
  • "Why this major?"
  • Short-answer questions about activities or experiences
Timeline tip: Don't leave supplements until the last week. Set milestone deadlines for each supplement in your planning tool.

Submitting Your Applications

When ready to submit:

  • Review every section for accuracy
  • Preview the application
  • Sign the application electronically
  • Pay the application fee (or submit fee waiver)
  • Click submit
Important: Submitting is final. You cannot edit after submission.

After Submission: The Part Common App Doesn't Cover

Once you submit, Common App's job is done. But yours isn't. Here's what comes next:

Immediately After

  • Confirm receipt (check school portals)
  • Submit any additional materials requested
  • Send official test scores if required

November - February

  • Complete FAFSA (opens October 1)
  • Submit CSS Profile if required
  • Apply for outside scholarships
  • Track school-specific financial aid deadlines

March - May

  • Review admission decisions
  • Compare financial aid packages
  • Visit accepted schools
  • Make final decision by May 1

May - August

  • Submit enrollment deposit
  • Housing deposit and preferences
  • Register for orientation
  • Health forms and immunizations
  • Course selection
That's 15+ deadlines per school that Common App doesn't track. This is exactly what Appffeine was built for.

Frequently Asked Questions

Can I edit my Common App after submitting to one school?

Yes, you can edit most sections before submitting to additional schools. Once submitted to a specific school, that version is final for that school.

Should I apply Early Decision or Regular Decision?

Early Decision is binding — only apply ED to your absolute top choice. Early Action is non-binding and gives you an earlier decision. Regular Decision gives you the most time. Consider your financial situation: ED commits you before seeing financial aid offers from other schools.

How long does it take to fill out Common App?

Most students spend 2-4 weeks completing their Common App, including essays. Start early (August-September) for the best experience.

What if a school isn't on Common App?

Check if they accept the Coalition Application or have their own portal. You can still track these schools alongside your Common App schools in Appffeine.
