Formula
Each section: Scaled Score = 1 + (Raw / Max Raw) × 35, rounded
Composite = Average of 4 section scores, rounded to nearest whole number
Example
English 60/75, Math 48/60, Reading 32/40, Science 30/40 → scores ~29, 29, 29, 27 → composite = 29 (~95th percentile)
Frequently Asked Questions
- The ACT has four sections: English (75 questions), Math (60), Reading (40), Science (40). Each section is scaled 1–36, and the composite is the average of all four, rounded to the nearest whole number.
- The national average composite is around 20. Scoring 25+ places you in the top 20%. For selective colleges, aim for 29+. For T20/Ivy-range schools, 33+ is competitive.
- Yes. You can take the ACT up to 12 times. Most students take it 2–3 times. Since 2020, ACT allows section-specific retesting, so you can retake only the sections you want to improve.
- The optional Writing section (40 minutes) produces a separate 2–12 score. It does not affect the composite. Some colleges require it — check individual school requirements.
