ACT Score Calculator

The ACT composite score is the average of your four section scores (English, Math, Reading, Science), rounded to the nearest whole number. Each section is scored 1-36. For example, if you score English 28, Math 26, Reading 30, Science 24, your composite = (28+26+30+24)/4 = 27. The composite also ranges from 1-36.

The national average ACT score is around 20. A score of 24+ puts you in the top 25% of test takers. Scores of 30+ are in the top 5% and competitive for selective colleges. For highly selective universities (Ivy League, MIT, Stanford), aim for 33+. However, 'good' depends on your target schools—check each college's middle 50% ACT range.

ACT benchmarks predict a 50% chance of earning a B or higher in corresponding college courses. The benchmarks are: English 18, Math 22, Reading 22, Science 23. Meeting these suggests college-level readiness in that subject. Many students exceed some benchmarks but not others—that's normal and helps identify areas for improvement.

Most colleges accept both equally. Try practice tests for each to see which feels better. The ACT has a Science section and is more straightforward; the SAT has no Science but includes more reading analysis. ACT is entirely multiple choice (except optional essay); SAT has some grid-in math questions. Choose based on your strengths.

Most students take the ACT 2-3 times. Scores typically improve with practice—the average improvement is 1-3 points. Many colleges superscore (take your best section scores across multiple tests), so retaking can help. Diminishing returns usually occur after 3 attempts. Check if your target schools superscore before planning multiple tests.
