How is the ACT composite score calculated?

The ACT composite score is the average of your four section scores (English, Mathematics, Reading, and Science), rounded to the nearest whole number. Each section is scored on a scale of 1–36. The Writing test, if taken, is scored separately on a scale of 2–12 and does not affect the composite score.

What is a good ACT score?

The national average ACT composite score is around 20–21. A score of 24 or above places you in the top 25% of test-takers, which is considered competitive at most colleges. For highly selective schools like Ivy League universities, MIT, or Stanford, a score of 34 or higher is typically in the middle 50% range of admitted students.

What does the ACT percentile mean?

Your percentile tells you what percentage of ACT test-takers scored lower than you. A 75th percentile score means you scored higher than 75% of students who took the test. Percentiles are based on recent graduating class data published annually by ACT, Inc.

How many times can I take the ACT?

You can take the ACT as many times as you want. Most students take it 2–3 times. Many colleges practice "superscoring" — taking your highest section score from each test date — which means retaking the ACT can only help your composite if you improve on any section.

Does the ACT Writing score affect my composite?

No. The ACT Writing (Essay) test is optional and its score (2–12) is reported separately. It has no effect on your composite score or on your English, Reading, or any other section score. Some colleges require or recommend the Writing test — check individual college requirements before your test date.

What is the difference between the ACT and SAT?

Both are standardised college admissions tests accepted at all US colleges. The ACT has four sections (English, Math, Reading, Science) plus an optional Writing test, scored 1–36. The SAT has two main sections (Evidence-Based Reading & Writing, Math) scored 400–1600. The ACT includes a dedicated Science section which the SAT does not. Neither test is universally preferred — choose based on which plays to your strengths.

What ACT score do I need for merit scholarships?

Merit scholarship thresholds vary widely by school. Many public universities offer automatic merit scholarships starting around 25–27. National Merit-linked scholarships (via PSAT/NMSQT) are SAT-based, but ACT scores in the 29–32 range often qualify for institutional scholarships at many private and public colleges. Check each school's financial aid page for exact thresholds.
