Raw per section to reach the target with equal section scores. Source: ACT enhanced-test practice forms (2025); the classic 75/60/40/40 form differs; tables vary by form.

The ACT changed in 2025: shorter sections and optional Science. Write your raws for English, Math and Reading (and Science if you took it); the sheet scales each to 1–36, averages them into the composite and circles it.

Worked examples

40/50, 32/45, 28/36: English 27, Math 27, Reading 27: composite 27, about the 87th percentile.
With Science: Add Science 34/40 = 30: the composite is the mean of four, 27.75, rounded to 28.
What you need for a 30: About 44 right in English, 36 in Math and 31 in Reading on the practice tables.

How it is calculated

Each section raw is mapped to a 1–36 scale score with the conversion table for that form. The composite is the average of English, Math and Reading (plus Science if taken), rounded to the nearest whole number with halves rounded up. Tables are from the enhanced-ACT practice forms; real forms vary by a point or two.
