About this tool

Your ACT composite is the average of your four section scores, rounded to the nearest whole number — but doing it by hand while planning retakes gets old. Enter English, Math, Reading and Science (each validated to a whole number from 1 to 36) and the tool returns the composite instantly, plus the unrounded mean so you can see how close you were to the next point. The explanation table spells out the arithmetic: each section listed with its score, the sum, the average, and the rounding rule applied (a .5 fraction rounds up). Use it to test scenarios — what a two-point Reading gain does to the composite — before deciding where to spend study time. Everything computes on this page; your scores go nowhere.
