Is AdmitGPT really free?

Yes. AdmitGPT is 100% free and open-source. There are no hidden fees, no paywalls, and no account required. The entire admissions model runs in your browser.

How does AdmitGPT calculate my admission chances?

AdmitGPT uses a transparent additive-logistic model that combines your academic strength (SAT/ACT/GPA z-scores), extracurricular spike, intended major fit, and international context into a single probability for each college. Every formula and weight is published openly.

Can AdmitGPT predict Ivy League acceptance chances?

Yes. AdmitGPT estimates admission probability for top-tier US universities including the Ivy League, MIT, and Stanford. It reports results as an honest, exploratory ordinal signal rather than a guaranteed probability, and openly documents its calibration limits.

Does AdmitGPT store or sell my data?

No. AdmitGPT performs all calculations client-side in your browser. Your profile is never uploaded, stored, or sold.

What GPA do I need for Harvard or Ivy League schools?

The median admitted GPA at Harvard and most Ivy League schools is approximately 3.95 unweighted. A GPA below 3.7 places you below the 25th percentile. Weighted GPAs above 4.0 are common among admitted students taking 8+ AP or IB courses. AdmitGPT normalizes your GPA against each school's own distribution for an accurate comparison.

What is a good SAT score for Ivy League admission?

The middle 50% SAT range across Ivy League schools is approximately 1460–1570. Harvard's range is 1490–1580. Scoring above 1550 places you at or above the 75th percentile at most Ivies. All Ivy League schools require test scores as of the 2025–26 cycle.

Does Early Decision really increase your chances?

Yes. Early Decision acceptance rates are typically 2–4x higher than Regular Decision at selective schools. For example, Dartmouth admits approximately 19% of ED applicants vs 4.5% for RD. However, ED is binding — you must enroll if admitted, so run net price estimates first. Non-binding Early Action offers a smaller boost (1.2–1.8x) with full flexibility.

Should I apply test-optional if my SAT score is low?

If your SAT is below a school's 25th percentile and the school offers test-optional admission, applying without scores is generally better. At test-required schools (all Ivies, MIT, Georgetown, etc.), you must submit regardless. At test-optional schools, a strong score (above the school's median) still helps admission and merit scholarships.

Can international students get financial aid at US colleges?

Only a handful of US schools are need-blind for international students: Harvard, Yale, Princeton, MIT, Dartmouth, Brown, Amherst, Bowdoin, and a few others. At these schools, financial need does not affect admission. At all other US universities, international students are evaluated on a need-aware basis — requesting aid can reduce your chances.

How many colleges should I apply to?

A balanced college list typically includes 8–12 schools: 2–4 safety schools (admission rate over 50% for your profile), 3–5 target schools (20–50% chance), and 2–3 reach schools (under 20% chance). Applying to more than 15 schools rarely improves outcomes and adds significant essay workload.

How accurate are college admission chances calculators?

No calculator can predict individual outcomes with certainty. AdmitGPT provides directional estimates based on historical data and is transparent about its limits. At schools below 10% admission rate, the model under-predicts systematically (predicted ~1.3% vs observed ~24.6% in the hardest decile). The ordinal ranking is reliable (AUC ~0.74).

What extracurriculars impress admissions officers most?

Admissions officers value depth over breadth. A single national-level achievement matters more than ten school-club memberships. AdmitGPT scores extracurriculars across six dimensions: tier (local to international), level, rarity, institutional strength, cognitive load, and validation. The spike contribution is capped at ±2.0 logit so no single activity can overpower academics.

Knowledge Base / Checklist

College Application Checklist

Applying to college involves dozens of components — and missing one can delay or derail your application. Here is everything you need, organized in priority order so you know what to do when.

1. Common App account and profile

Create your Common App account at commonapp.org. The 2026–27 application opens August 1. Fill in your personal information, family background, education history (courses, GPA, class rank), and test scores. This section is straightforward but time-consuming — do it early to avoid errors under deadline pressure.

2. Teacher recommendations

Most selective schools require two teacher recommendations and a counselor recommendation. Ask teachers who know you well in core academic subjects from junior year. Ask early — the first week of senior year — and give them a packet with your resume, a list of colleges and deadlines, and anything you want them to mention. Great letters include specific anecdotes; generic praise helps nobody.

3. Personal essay (Common App)

The Common App personal statement is 650 words, submitted to every school. The prompt matters less than the story. Write about a specific moment or experience that reveals who you are. Avoid cliché openers, thesaurus vocabulary, and resume rehashing. Draft in June, revise in July, finalize in August — do not still be writing this in October. See our essay tips guide for a deeper breakdown.

4. Extracurricular activities list

The Common App has 10 activity slots with 150 characters each. List your most meaningful activities first. Write like a micro-resume: strong verb, quantifiable impact, what you actually did. Include leadership roles, awards, and time commitment. For help prioritizing your activities, see our extracurricular scoring guide.

5. Test scores and transcripts

Request official SAT or ACT scores from the testing agency 2–3 weeks before each deadline. Request your high school transcript from your guidance counselor at least two weeks in advance. If you are applying test-optional at some schools, confirm each school's policy on the Common App (you choose per school).

6. Supplemental essays

Supplemental essays — especially "Why This School?" — are where decisions are made at selective schools. Each supplement should reference specific programs, professors, or opportunities at that school. Generic answers are immediately obvious. Start these in August or September, not October.

7. Financial aid forms

File the FAFSA as soon as it opens. File the CSS Profile if any of your schools require it. Check each school for institutional aid deadlines — many are earlier than you think. Missing a financial aid deadline is the most expensive mistake in the entire process.

8. Final submission

Review every application for typos, incomplete sections, and incorrect school names (one of the most common errors). Submit 48–72 hours before the deadline — Common App servers are notoriously unreliable on deadline day. After submitting, confirm that your recommendations, transcripts, and test scores have been received.

Check your admission odds early

Before you submit everything, use the AdmitGPT calculator to see your estimated probability at each school. Knowing which schools are reach, target, or safety helps you prioritize your essay writing and application energy.
